Temperature fluctuation and plant water status affect root pressure (xylem sap exudation “bleeding”) during budding or grafting. An experiment was conducted to find the optimum irrigation regime for patch budding (in July) and tongue grafting (in March) of Persian walnut on Juglans regia rootstock under three environmental conditions (greenhouse, shade-house and outdoor). The grafted/budded plants were subjected to three irrigation regimes including 1-day, 3-day and 7-day for 4 weeks after grafting/budding. Callus formation and quality, and graft/bud-take were recorded after four weeks. The survival rate and growth of the scions were measured after three months. Based on the results, grafting success under greenhouse, shade-house and outdoor conditions were 66.7%, 42.6% and 17.6%, respectively. The highest graft/bud take (94.4%) was obtained under greenhouse...

Although this technique improves the grafting success and propagation efficiency, it is technically more demanding than the conventional walnut grafting procedures and is yet to be optimized. This study was aimed to investigate the influence of rootstock type (dwarf and standard genotypes), graft union covering materials (perlite, sawdust, coco-peat and perlite at 1:1 ratio, and without cover - control) and different epicotyl grafting procedures (Gandev-Arnaudov and Frutos) on grafting success and performance of the grafted plants in order to optimize the walnut epicotyl grafting. Walnut seedlings were grown in a greenhouse. After four weeks, dormant shoots of walnut ‘Chandler’ were grafted to the epicotyl of young walnut seedlings. Grafting success and callusing quality were recorded 30 days after grafting. Growth parameters of the grafted plants, including number of nod...

In the experiment, half-sib seedlings of the varieties were subjected to high (100 mM) and severe (200 mM) levels of NaCl-induced salinity for 90 days. Growth, physiological, biochemical and ionic parameters in the roots and shoots of plants were measured in the experiment. Salinity markedly declined plant growth, and increased the number of necrotic leaves (NL) and leaf abscission. In terms of physiological responses, salinity reduced the relative water content (RWC), membrane stability index (MSI) and the concentrations of photosynthetic pigments, but increased carbohydrates and proline content in the leaves. MSI of the leaves was positively correlated with the concentrations of anthocyanins and carotenoid...

One of the fields was located at Neka town with 5 meter s above sea level and other one was at sari city with 905 meters above sea level. Weeds treatment (control and without control) was chosen as main factor and nitrogen treatment (0, 23, 46, 69, 92 kg h) as sub-factor. Results showed that bending moment 3 and 4 inter-nodes at Neka town area (15.56 and 8.74 %) was more than sari city area respectively. With weeds control increased grain yield (40.73 %) because of less inter-specific competition and increase panicle length. Maximum grain yield was obtained for nitrogen treatment (69 and 92 kg h) because of increase in panicle length. Bending moment 3rd and 4 inter-nodes (28.32 and 22.61 %) increased in nitrogen treatment (92 kg h) over control because of increase in plant height, stem length, 3 and 4 inter-nodes length and 3 and 4 inter-nodes diameter. Minimum and maximum height, number and weeds dry weight were fo...

To evaluating effects of deficit irrigation (DI) on growth, yield, yield components and water-use efficiency (WUE) in cantaloupe crop (Cucumis melo L.) under semi-arid conditions, a field experiment based randomized completely block design (RCBD) with three replications was conducted. In this experiment, three irrigation treatments consisted of 60 (I60), 80 (I80), and 100% ETc (I100, Control) were applied during the growing season. Based on the results, the highest total crop yield (30.3 t ha-1), mean number of fruits per plant (4.9), mean fruit weight (1.508 g), plant main stem length (194.6 cm) and total leaf area (24.375 cm2) were obtained in I100, while highest chlorophyll (Chl) a, total Chl content and Chl stability index obtained at I80 treatment. Moderate water stress (I80) did not reduce cantaloupe yield but led to increase WUE and total soluble solids (TSS). Under I60 treatment, the yield...

This experiment was conducted during winter to spring 2014 to optimize the seed germination of walnut ‘Chandler’ via changing growing media and removing seed mechanical dormancy. Fourteen treatments were tested. None of the seeds germinated without any treatment on shell or while they stored in manure. Germination percent of cracked seeds (CS) and cracked with toothpicks inserted seeds (CTS) without any stratification period reached up to 66.1% and 83.7% with mean germination time (MGT) of 0.73 and 0.98 day, respectively. Considering a 45-day cold storage period improved germination percentage of CS and CTS up to 88.3% and 94.1% with MGT of 1.02 and 1.12, respectively. Seedling growth parameters significantly increased after the cold storage period. Based on the results, mechanical dormancy was suggested as the main limiting factor ...

Fertilizer treatments were including: 100% nitrogen and phosphate as chemical fertilizers (T1), 50% nitrogen and 100% phosphate and root inoculation and irrigation with Nitroxin in transplanting stage (T2), 100% nitrogen and 50% phosphate and root inoculation and irrigation with Bio-phosphate in transplanting stage (T3), 50% nitrogen and 50% phosphate and root inoculation and irrigation with Nitroxin and Bio- phosphate in transplanting stage (T4), 50% nitrogen and 50% phosphate, and root inoculation in transplanting stage and irrigation with Nitroxin and Bio-phosphate in transplanting and flowering stages (T5), Nitroxin and Bio-phosphate alone (T6).

The experimental design was a completely randomized factorial experiment with two factors, namely: (i) Two nitrogen forms (Ca(NO3)2 and (NH4)2SO4) and (ii) Three O2 levels of the nutrient solutions (1±0.3, 2±0.3, 3±0.3, and 4±0.3 mg L O2). The results showed that ammonium application reduced all measured parameters of vegetative growth, whereas high oxygen levels increased the vegetative growth. Comparing with nitrate-N, ammonium application increased the concentrations of NPK and Zn in leaves and Zn and Cu in roots, while it decreased the concentration of Mg, Ca, Cu, Mn, and Na in leaves and Ca, Mg, Mn, and Na in roots. High levels of O2 increased N, Mg, Ca, Cu, and Mn content of leaves, as well as Mn and Na content in roots, while it decreased the concentration of K in leaves and P and Zn in roots. According to the results,...

In this experiment, three deficit-irrigation (DI) treatments based on 60, 80 and 100% crop evapotranspiration (ETc) were applied in a randomized completely block design (RCBD) under field conditions. Based on the results, DI levels had a significant effect on height, number leaves per plant, leaf area, shoots wet and dry weight, sugar content and yield. Increasing irrigation levels increased height, number of leaves per plant, leaf area, shoots wet and dry weight, chlorophyll index and yield. Fruit yield of treatments were 19.6, 28.3 and 30.3 t ha -1 at 60%, 80% and 100% ETc, respectively. There was no significant difference between 80 and 100% ETc in terms of yield. The highest height (194.7 cm), number of leaves per plant (243.3), leaf area (24375 cm 2 ) and shoots wet and dry weight (1135.9 and 111.6 g, respectively) obtained at 100% ETc. While, sugar ...

With the increasing role and importance given to nuts (i.e., walnuts, hazelnut, pistachio, pecan, almond) in a balanced and healthy diet and their benefits to human health, breeding of the nuts species has also been stepped up. Most recent fruit breeding programs have focused on scion genetic improvement. However, the use of locally adapted grafted rootstocks also enhanced the productivity and quality of tree fruit crops. Grafting is an ancient horticultural practice used in nut crops to manipulate scion phenotype and productivity and overcome biotic and abiotic stresses. There are complex rootstock breeding objectives and physiological and molecular aspects of rootstock–scion interactions in nut crops. In this review, we provide an overview of these, considering the mechanisms involved in nutrient and water uptake, regulation of phytohormone...
