A two-year field study was carried out at the Southeastern Anatolia Agricultural Research Institute (SAARI), in 2009 and 2010, with the aim of evaluating 12 cotton genotypes for yield and fiber quality properties under irrigated and water stress conditions. The experiment was laid out as a randomized split block design (RSBD) with four replications. Significant differences were observed among genotypes and water treatments for seed cotton yield, fiber yield, ginning percentage and all fiber quality properties except fiber uniformity. Yield differences among genotypes under water stress and non-stress conditions were higher during the first season. In both years, SER-18 and Stoneville 468 cotton genotypes produced higher yield under water stress conditions, while Stoneville 468 produced higher yield under well-irrigated conditions. The results during the two years indicated that seed cotton yield decreased (48.04%) and fiber yield decreased (49.41%), due to water stress. Ginning percentage and fiber quality properties were also negatively affected by water stress treatment. Fiber length, fiber strength, fiber fineness and fiber elongation were decreased, while fiber uniformity was not affected by water stress treatment.

The endocannabinoid system (ECS) acts as a modulator in the activation of the microcirculation, immune system, and autonomic nervous system, along with controlling pharmacological functions such as emotional responses, homeostasis, motor functions, cognition, and motivation. The ECS contains endogenous cannabinoids, cannabinoid receptor (CBRs), and enzymes that regulate their biosynthesis, transport, and degradation. Moreover, phytocannabinoids and synthetic cannabinoids that mimic the action of endocannabinoids also play an essential role in the modulation of the ECS. Cannabinoids, the main constituents of cannabis (Cannabis sativa L.), are therapeutic compounds that have received international attention in the health field due to their therapeutic properties. Recently, they have been tested for the treatment of COVID-19 due to their antiviral properties. Indeed, cannabinoid-type compounds, and in particular cannabidiol (CBD), isolated from glandular trichomes found in the calyx of cannabis flowers with reported antiviral properties is hypothesized to be a therapeutic option in the ministration of SARS-CoV-2 consorted with COVID-19 disease. The relevant articles were determined from the database search published mainly in Web of Science, Google scholar, PubMed, Crossref, and ClinicalTrials.gov database during the pandemic period. The articles were evaluated for the therapeutic potentials, mechanisms of action of cannabinoids, the roles of the ECS in the immune system, impact of cannabinoids in SARS-CoV-2 septic, especially if they address the application of cannabinoids as drugs for the curability and management of SARS-CoV-2 and its novel variants. Although the evidence needed to be considered using cannabinoids in the control and treatment of viral diseases is currently in its infancy, they already offer an opportunity for clinicians due to their effects in relieving pain, improving appetite, and improving childhood epilepsy, especially in cancer and human immunodeficiency virus (HIV/AIDS) patients. In addition to these, the most recent scientific evidence emphasizes their use in the treatment of the coronavirus infected patients. In brief, all preclinic and clinic studies that have been reported show that, through the cannabinoid system, cannabinoids, particularly CBD, have many mechanisms that are effective in the treatment of patients infected by SARS-CoV-2. Thus, more extensive studies are necessary in this area to fully identify the effects of cannabinoids on SARS-CoV-2.

In contrast to standard soil moisture measurements, good results might be acquired in a shorter time over large areas by remote sensing tools. In order to estimate the soil moisture over vegetated agricultural areas, a relationship between Radarsat-2 data and measured ground soil moistures was established by polarimetric decomposition models and a generalized regression neural network (GRNN). The experiments were executed over two agricultural sites on the Tigris Basin, Turkey. The study consists of four phases. In the first stage, Radarsat-2 data were acquired on different dates and in situ measurements were implemented simultaneously. In the second phase, the Radarsat-2 data were pre-processed and the GPS coordinates of the soil sample points were imported to this data. Then the standard sigma backscattering coefficients with the Freeman-Durden and H/A/α polarimetric decomposition models were employed for feature extraction and a feature vector with four sigma backscattering coefficients (σhh, σhv, σvh, and σvv) and six polarimetric decomposition parameters (entropy, anisotropy, alpha angle, volume scattering, odd bounce, and double bounce) were generated for each pattern. In the last stage, GRNN was used to estimate the regional soil moisture with the aid of feature vectors. The results indicated that radar is a strong remote sensing tool for soil moisture estimation, with mean absolute errors around 2.

For this purpose, 350 soil samples representing the research area were taken and some properties were determined. The research results showed that soil samples were mostly loamy-clay textured, had slightly or middle alkaline pH, contained varying amounts of lime and showed no signs of salinity problem. Moreover 92.91 % of the soils had insufficient organic matter content. As the soils in the research area are generally loamy-clay textured and their organic matter content is insufficient, soil cultivations should be applied at appropriate soil moisture contents and organic matter should be supplied to the soils to enhance growth of plants cultured in the soils in question.

The selected cotton varieties were harvested both in-season and out of season where they were exposed to weathering conditions including rain. The experiment was conducted on the farmer's field at Cagıl village in Kızıltepe/Mardin, a major cotton production area, during the 2009 cotton growing season. The experimental design was arranged as Split Plots in Randomized Complete Blocks with four replications. Three different cotton varieties namely Stoneville 468, GW- Teks and DP 388 were used as plant materials. The results showed that there were significant differences between the different harvesting times in terms of fiber length, fiber strength, fiber fineness and fiber elongation. On the other hand, short fiber index, fiber uniformity, fiber maturity and fiber moisture were not affected by the different harvesting times. In addition, there were si...

The study was carried out at the Southeastern Anatolia Agricultural Research Institute during 2006 and 2007 cotton growing season. Seven cotton lines (which are known as high quality) and three testers (which are known as well adapted and high yielding) were crossed in a line x tester mating design in 2006. Ten genotypes and 21 F 1 hybrids were planted in the randomized complete block design with three replications at the same experimental area in 2007. The variance due to GCA and SCA were highly significant for all the traits studied. This indicated that both additive and non-additive gene effects were responsible for the investigated characters. From the trial it was found that in the population, fiber length, fiber fineness and fiber elongation were influenced by additive gene effects while seed cotton yield, fiber yield, ginning percentage, fiber strength and fiber uniformity were influenced by non-additive gene effects. Among the parents FiberMax 832, Teks, Stoneville 453 and Maraş 92 for seed cotton yield and fiber yield; Aşkabat 71 and Giza 45 for fiber length and fiber strength; Aşkabat 71 for fiber fineness and fiber uniformity were detected with higher general combining ability. Most of the parents except Aşkabat 71, Giza 45 and Maraş 92 exhibited GCA for ginning percentage. SCA was significant for FiberMax 832 x Stoneville 453, Tam 94 L 25 x Maraş 92 and Teks x Stoneville 453 hybrid combinations for yield with acceptable fiber quality.

Inheritance and interrelationships of earliness characters were evaluated in a line)tester design. Three intermediate-early-maturing female (lines) which are grown regionally and four early-maturing males (testers) cotton varieties were crossed in 2003. The twelve F 1 and seven parents were planted randomized block design with three replications in 2004. For each earliness trait, general combining ability (GCA) and specific combining ability and gene effects were estimated using the line)tester method of analysis and also were determined heterosis and narrow sense heritability. Parents and their hybrids (except the monopodial branch) were significant for all the earliness traits studied. Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for date of first square, date of first flowers and harvested rate of first picking. Among the lines, Ersan 92 and Maras 92 and among the testers Acala Royal was found to be the best general combiners for most of the earliness characters. Four out of twelve crosses namely Ersan 92)Chirpan 603, Ersan 92)Acala Maxa, Maras 92)Acala Royal and Nazilli 87)Acala Royal were found to be the best crosses for investigated earliness characters.

Genotypes showed statistically significant differences for stomatal conductance, photosynthetic yield, fluorescence, photosynthetically active radiation (PAR), seed cotton yield, plant height, boll weight, seed cotton weight, number of seeds per boll and 100 seed weight. In the study, relative cell injury level (RCIL), ranged from 54.56 to 79.44% and stomatal conductance ranged from 264.86 to 570.50 mol m-2 s-1. Associations between investigated traits indicated that there were some positive correlations. These data indicated that photosynthetic yield, fluorescence, chlorophyll content (SPAD value), cell membrane thermostability (CMT), plant height and number of bolls per plant can be used for improving seed cotton yield. However, among these measurements CMT, SPAD value and fluorescence were more practical in large breeding trials. The results showed that AGC 375 and AGC 208 cotton varieties had lower relative cell injury level (higher cell membrane thermostability) and higher seed cotton yield and photosynthetic yield than other investigated varieties.
