Dans les études comparées « droit et littérature » ou « économie et littérature », on cherche souvent en priorité ce que la littérature peut nous apprendre sur le droit ou l’économie. C’est prendre un risque : celui d’oublier la
dimension littéraire des textes étudiés. À plus forte raison, c’est prendre le risque de passer à côté d’un fait précieux, à savoir que la littérature est autre chose qu’un instrument talentueux assigné à la valorisation des thèmes qu’on lui livre : la littérature est plus que cela ! Elle sait elle-même user des autres – en l’occurrence, user du droit et de l’économie comme d’instruments, les mettre à son service. Il n’est pas rare que, ne cherchant pas à représenter ces deux univers, elle les détourne de leurs fins, les vide de leurs fonctions manifestes, mais en conserve mécanismes, raisonnements et vocabulaire : la littérature tire du droit et de l’économie des éléments de poétique qu’elle s’agrège et qui la renforcent, sans qu’elle se soucie de nous apprendre nécessairement quelque chose sur ces deux disciplines, objet de son pillage.

In the most comprehensive study to date we explored the phylogeny and evolution of the genus Asparagus, with emphasis on the southern African species. We included 211 accessions, representing 77 (92%) of the southern African, 6 (17%) of the tropical African, 10 (56%) of the strictly European and 6 (9%) of the Eurasian species. We analysed DNA sequences from three plastid regions (trnH-psbA, trnD-T, ndhF) and from the nuclear region phytochrome C (PHYC) with parsimony and maximum likelihood methods, and recovered a monophyletic Asparagus. The phylogeny conflicts with all previous infra-generic classifications. It has many strongly supported clades, corroborated by morphological characters, which may provide a basis for a revised taxonomy. Additionally, the phylogeny indicates that many of the current species delimitations are problematic. Using biogeographic analyses that account for phylogenetic uncertainty (S-DIVA) and take into account relative branch lengths (Lagrange) we confirm...

Milk production is a complex physiologic process involving physical and emotional factors and the interaction of multiple hormones. Galactogogues are medications or other substances believed to assist initiation, maintenance, or augmentation of milk production in animals. Most galactagogues (e.g., medications, foods, herbal therapies etc.) exert their pharmacologic effects through interactions with dopamine receptors, resulting in increased prolactin levels and thereby augmenting milk supply. Numerous botanicals have been used as galactagogue in folk medicine. The most commonly used are:

A variety of methodologies, such as the Foreign Trade Competitiveness Index, the Foreign Trade Policy Index and the Tradecan competitiveness matrix, reveal a process of adaptation to changes in world trade in the period from 2002 to 2012, within the context of the so-called "complex adaptive system" as a transition from the fourth to the fifth technological revolution in fresh asparagus exports from Peru. The country's competitiveness map shows that it is not competing globally at the international level but rather partially or regionally. Mexico is its main competitor, with comparative advantages over Peru because of its currency's real exchange rate against the United States dollar, but there are challenges that need to be dealt with in the medium term in this process of adaptation to change.

Asparagus officinalis L. is a dioecious plant. A region called the M-locus located on a pair of homomorphic sex chromosomes controls the sexual dimorphism in asparagus. The aim of this work was to clone the region determining sex in asparagus from its position in the genome. The structure of the region encompassing M should be investigated and compared to the sex-determining regions in other dioecious model species. To establish an improved basis for physical mapping, a high-resolution genetic map was enriched with AFLP markers closely linked to the target locus by carrying out a bulked segregant analysis. By screening a BAC library with AFLP-and STS-markers followed by chromosome walking, a physical map with eight contigs could be established. However, the gaps between the contigs could not be closed due to a plethora of repetitive elements. Surprisingly, two of the contigs on one side of the M-locus did not overlap although they have been established with two markers, which mapped in a distance as low as 0.25 cM Xanking the sex locus. Thus, the clustering of the markers indicates a reduced recombination frequency within the M-region. On the opposite side of the M-locus, a contig was mapped in a distance of 0.38 cM. Four closely linked BAC clones were partially sequenced and 64 putative ORFs were identiWed. Interestingly, only 25% of the ORFs showed sequence similarity to known proteins and ESTs. In addition, an accumulation of repetitive sequences and a low gene density was revealed in the sex-determining region of asparagus. Molecular cytoge-netic and sequence analysis of BACs Xanking the M-locus indicate that the BACs contain highly repetitive sequences that localize to centromeric and pericentromeric locations on all asparagus chromosomes, which hindered the locali-zation of the M-locus to the single pair of sex chromosomes. We speculate that dioecious Silene, papaya and Asparagus species may represent three stages in the evolution of XX, XY sex determination systems. Given that asparagus still rarely produces hermaphroditic Xowers and has homomorphic sex chromosomes, this species may be an ideal system to further investigates early sex chromosome evolution and the origins of dioecy.

In order to study the in vitro callus induction and plant regeneration in the asparagus plant (Asparagus officinalis ) and indirect organogenesis in explants, an experiment in a completely randomized design was performed in tissue culture laboratory of faculty of agriculture, Islamic Azad University of Dezfool. In this study, the nodal explants treated with different concentrations of NAA and BAP, and it was found that the presence of two plant growth regulators NAA And BAP Is necessary for seedlings regeneration and callus induction in asparagus,. Treatment that leads to achieving the maximum amount of callus buds was MS medium supplied with 0.5 mg/lit of NAA and 1 mg/lit BAP which leads to the production of 22 buds per explants. Two different levels of 2, 4-D were used for induce roots in regenerated seedlings. The best treatment was 1.25 mg/ lit 2, 4-D with an average of 52% rooting in regenerated plants.

Additionally, the phylogeny indicates that many of the current species delimitations are problematic. Using biogeographic analyses that account for phylogenetic uncertainty (S-DIVA) and take into account relative branch lengths (Lagrange) we confirm the origin of Asparagus in southern Africa, and find no evidence that the dispersal of Asparagus follow the Rand flora pattern. We find that all truly dioecious species of Asparagus share a common origin, but that sexual dimorphism has arisen independently several times.

Ethno botanical studies were carried out to collect information on the use of Medicinal tree species by the tribal people of Munchangiputtu Mandalam, who live in forests of interial hills in Visakha patnam district, Andhra Pradesh, India. Ethnomedicinal uses of 69 tree species along with local name, botanical name, family, part used, ailments for which the drug is administrated, mode of administration are presented. They belong to 57 genera and 33 angiosperms families. These plants use to cure different type of ailments. Most remedies were taken orally, accounting for 60 % of medicinal use. The most widely sought after plant parts in the preparation of remedies in the areas are the stem bark and leaves. Tribal people have high number of medicinal plant species for the treatment of different type of diseases.

Disease suppression of Fusarium crown rot and the changes in free amino acid contents in mycorrhizal asparagus (Asparagus officinalis L., cv. “Welcome”) plants were investigated. Sixteen weeks after arbuscular mycorrhizal fungus (AMF; Glomus intraradices) inoculation, mycorrhizal plants showed higher dry weight of shoots than non-mycorrhizal plants, and AMF colonization level in a root system reached up to 73.3%. Ten weeks after Fusarium proliferatum (Fp; N1-31, SUF1207) inoculation, control plants showed 100% incidence and high severity in the 2 Fp isolates. However, AMF plants showed lower severity than non-AMF plants in the 2 Fp isolates. Ten weeks after Fp (N1-31) inoculation, the increase in 7 constituents of amino acids (glutamine, arginine, aspartic acid, alanine, citrulline, GABA, glycine) in shoots, and 9 in roots (asparagine, arginine, threonine, serine, glutamine, citrulline, valine, GABA, histidine) occurred in AMF plants. From these findings, plant growth promotion and suppression of Fusarium crown rot occurred in mycorrhizal asparagus plants, and the disease tolerance was supposed to be associated with the symbiosis-specific increase in free amino acids.

Since ancient times, plants and herbal preparations have been used as medicine. Research carried out in last few decades has certified several such claims of use of several plants of traditional medicine. Popularity of Momordica charantia (MC) in various systems of traditional medicine for several ailments (antidiabetic, abortifacient, anthelmintic, contraceptive, dysmenorrhea, eczema, emmenagogue, antimalarial, galactagogue, gout, jaundice, abdominal pain, kidney (stone), laxative, leprosy, leucorrhea, piles, pneumonia, psoriasis, purgative, rheumatism, fever and scabies) focused the investigator's attention on this plant. Over 100 studies using modern techniques have authenticated its use in diabetes and its complications (nephropathy, cataract, insulin resistance), as antibacterial as well as antiviral agent (including HIV infection), as anthelmintic and abortifacient. Traditionally it has also been used in treating peptic ulcers, interestingly in a recent experimental studies have exhibited its potential against Helicobacter pylori. Most importantly, the studies have shown its efficacy in various cancers (lymphoid leukemia, lymphoma, choriocarcinoma, melanoma, breast cancer, skin tumor, prostatic cancer, squamous carcinoma of tongue and larynx, human bladder carcinomas and Hodgkin's disease). There are few reports available on clinical use of MC in diabetes and cancer patients that have shown promising results.

BACKGROUND: The asparagus miner is a putative vector of Fusarium spp., which have been implicated in globally declining asparagus production. Growers currently apply broad-spectrum insecticides for the asparagus miner, but lack management guidelines for adequately controlling the pest. Our aims were (1) to determine the lower developmental threshold of the asparagus miner, (2) develop and validate a degree-day model describing its phenology, and (3) create a developmental time budget for the asparagus miner to help guide growers' management decisions. RESULTS: We found that the lower developmental threshold for the asparagus miner was 12.1 • C, and that the phenology of the asparagus miner could be reliably predicted over the course of a two-year study. Predictions from the model match well with previously published information on the bionomics of the asparagus miner, but fit better for sampling data collected from the midwestern and eastern United States than for the United Kingdom. The life cycle of the asparagus miner likely requires between 1500 and 2000 degree-days to complete; the longest developmental time requirement was for the pupal stagen CONCLUSION: This study provides tools for the targeted management of the asparagus miner by offering a degree-day model that may be used to predict its life stages in the north-eastern United States.

Wild asparagus, Asparagus acutifolius L., produces edible spears used in local diets of Mediterranean countries for millenia. Recently, interest has risen for its cultivation as frugal crop for niche markets, but only limited information exists on the nutritional values of this vegetable. In this paper, the nutritional values and metabolic profile (i.e. moisture content, total proteins, lipids and phenols, folic

Nanoparticles recently play remarkable roles in modern agriculture and biotechnology due to specific exclusively physicochemical and biological characteristics of the particles. In recent years, nanoparticles are been using as fertilizers and elicitors to improve crops. Nutritionists are constantly seeking natural antioxidants without side effects to using for healthcare and treatment. Asparagus officinalis L. as medicinal plant treated by iron (0, 10, 50 and 100 mg/L) and selenium (0, 0.5, and 1 mg/L) nanoparticles as nano elicitors. Then the antioxidant capacity of A. officinalis L. was detected and measured by α, α-diphenyl-β-picrylhydrazyl (DPPH) assay, for assessment of the antioxidant activity. The iron nanoparticles concentration significantly increases the antioxidant activity of both male and female asparagus stem, as well as selenium nanoparticles. When combined iron and selenium used as nano elicitors then cause the antioxidant activity significantly decreases. But the integration of two nano elicitors (iron and selenium) decreased antioxidant capacity while the use of nano-selenium could enhance antioxidant capacity. The application of nano elicitor increased antioxidant capacity in the female stem than male.

The main aim of this paper is to present the classification and identification of the plant known in Classical Greek as ἀσφάραγος and in Latin asparagus. The interest in plants in ancient times was rather big and in consequence led to splitting the Botany as a separate scientific category, which finally materialised in the works of Theophrastus of Eresos. He was the first amongst the Greek Philosophers to treat the Plant Science independently, excluded from Medicine or Pharmacy, performed for itself.
Theophrastus in his Enquiry into Plants mentions four times the Greek name ἀσφάραγος. In this paper I will focus on what pieces of information about the plant the Greek Author gives and how these can be related to modern botany. To present the history of asparagus in Antiquity in full perspective I will also get some pieces of information from Pliny the Elder’s Natural History. This action of identifying the plant will allow me to perform the second part of the paper, which includes reconstruction of recipes preserved in Apicius’ De re coquinaria.
The usage of asparagus in Culinary Art is well now as per nowadays, but this is not the invention of the modern times that the asparagus found its place in the culinary tradition. Over the centuries the Greek and Latin authors like Discurides, Galen and others appreciated the plant, but as the Apicius’ cookbook is the only Ancient culinary book preserved to our times, I will focus mainly on the recipes placed there. All in all this shall give the image, how the plant could have been used and the reconstructions of the recipes will allow to the Ancient Rome a bit

A research work was conducted to find out the chemical composition of Asparagus densiflorus sprengeri under the influence of different agro-climatic conditions of Punjab province, Pakistan. Experiment conducted with Complete Randomized Design (CRD). Triplicate samples of shoots and roots collected from various localities were analyzed for each treatment. Fresh plants of A. densiflorus sprengeri were collected from seven different sites of Punjab. Time of sampling is from March to April. After air drying, samples were analyzed for their Malondialdehyde (MDA), Ascorbic Acid (AsA) and Total Phenolic (TPhe). MDA, AsA and TPhe concentrations differed significantly (p<0.05) from locality to locality. As the contents of MDA concerned the maximum concentrations were recorded from the shoot (4.54 ± 0.027 mg g-1) and root (3.03 ± 0.307 mg g-1) of plants selected from University of Agriculture, Faisalabad (UAF) and TT Singh respectively while the lowest from shoot (1.13 ± 0.165 mg g-1) and root (0.94 ± 0.120 mg g-1) collected from Multan and UAF respectively. The highest AsA concentrations of shoot (0.436 ± 0.0023 mg g-1) and root (0.424 ± 0.0035 mg g-1) were recorded from UAF and Govt. College University, Faisalabad (GCUF) respectively whereas minimum of AsA of shoot (0.206 ± 0.0008 mg g-1) and root (0.224 ± 0.0093 mg g-1) from TT Singh. The highest TPhe were present in the shoot (0.451 ± 0.019 mg g-1) and root (0.529 ± 0.019 mg g-1) of plants collected from UAF and Nursery (Faisalabad) respectively while minimum of shoot (0.165 ± 0.0065 mg g-1) and root (0.265 ± 0.012 mg g-1) from Multan and TT Singh respectively. On the basis of results obtained it can be concluded that environmental conditions significantly (p<0.05) influenced the chemical composition of A. densiflorus.

The performance of asparagus (Asparagus offi cinalis L.) under the desert conditions of the Arabian Peninsula was evaluated. Ten cultivars introduced from six countries were studied. Two months old seedlings were transplanted into fi eld plots in February 2007 and spears produced in the second year were harvested over a period of four weeks. Signifi cant differences were found among cultivars for the number and quality of spears. The average number of spears harvested per plant varied between 5.0 and 26.4 and the spear yield between 36.3 and 159.2 g plant-1. The spear number and yield were highest in cultivar PI 277824. Seed yields from the fi rst year of harvest varied from 29.7 to 136.2 g plant-1 among cultivars. In many cultivars, spear yields obtained in the second year were comparable to the yields reported from the productive environments in the tropics. The results show that asparagus has considerable potential for cultivation under the desert conditions of the Arabian Penins...

The common and spotted asparagus beetles (Crioceris asparagi (L.) and Crioceris duodecimpunctata (L.), respectively) are host-specific pests of asparagus, and frequently occur wherever asparagus is grown. The common asparagus beetle is the more serious of the two pests. It emerges earlier in the season, and both adults and larvae can cause damage to the asparagus crop by chewing spears and removing fern. This article describes morphological features of both asparagus beetles, discusses aspects of their life cycle and ecology, and addresses management strategies such as pesticides, biological, and cultural controls.
