The Effect of Humic Acid on the Growth and Physiological Indices of Pistachio Seedling (Pistacia vera) under Drought Stress
This study was carried out to evaluate the effect of soil application of humic acid on growth and physiological indices of pistachio seedlings ("Badami Zarand" rootstock) under drought stress. This experiment was arranged as a completely randomized design with three replications in greenhouse conditions. The experimental treatments consisted of humic acid (0, 30 and 60 gr in 4 kg-1 soil in pot) and irrigation intervals (7, 20 and 30 days). The studied growth parameters included of stem height, leaf number, leaf area, stem diameter, biomass of root and shoot and physiological indices in leaves such as relative water content (RWC), relative water loss (RWL), leaf water content (LWC), excised leaf water retention (ELWR), excised leaf water loss (ELWL) and relative water protection (RWP). In this experiment, the results showed that relative water content reduced and relative water loss increased in leaf in irrigation interval of 30 days. The results indicated that the application of humic acid increased the vegetative growth of pistachio seedling in comparison with the control under high irrigation interval (p<0.05). The results also showed that relative water content and relative water protection significantly increased with the application of humic acid (p<0.05). These results indicated that the pistachio seedlings were sensitive to water stress and the application of humic acid under drought stress could be an appropriate management strategy to improve the growth of seedlings in pistachio orchards in arid and semi-arid areas of Iran.

The Effects of Humic Acid and Calcium on Morpho-Physiological Traits and Mineral Nutrient Uptake of Pistachio Seedling under Salinity Stress
The study was carried out to evaluate the effects of soil application of humic acid and calciumon morpho-physiological traits and Na+, Mg2+, Ca2+ uptake of Pistachio seedling (Akbari) grown under salt stress. A completely randomized design was used with four replications in greenhouse conditions. The experimental treatment consisted of four levels of humic acid (Bis humic) (0, 4, 8 and 12 gr k...متن کامل
The Effects of Foliar Application of Salicylic Acid and Ascorbic Acid on Morpho-Physiological Traits of Pistachio Seedlings under Drought Stress
This study was carried out to investigate the effects of foliar spray of salicylic acid and ascorbic acid on some morpho-physiological traits of Pistacia vera cv. Badami-zarand under drought stress. The experiment was conducted during 2017-2018 in the greenhouse condition, in a factorial randomized complete block design with three replications on pot plants. The soil texture of experim...متن کامل
the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The Effects of Spermine and Salicylic Acid on Pistachio (Pistacia vera L.) Cultivars (Badami and Qazvini) under Copper Stress
The aim of this study was to identify the effect of Spermine and Salicylic acid on several growth parameters, such as shoot length, shoot fresh and dry weights, amount of protein and carbohydrate, of Badami and Qazvini pistachio cultivated variety under copper stress. The experiment design was completely randomized with three replicates per treatment and four levels of copper (o.5, 30, 45, 60 µ...متن کامل
