in order to evaluate the effects of foliar application of methanol on some physiological characteristics of chickpea under drought stress, an experiment was conducted as a factorial based on completely randomized design with three replications in 2011 at the recearch center of plant for sciences in ferdowsi university of mashhad. the first factor was different levels of methanol including, 0 (c...

This study was conducted to determine effect of water stress on chlorophyll content and chlorophyll fluorescence parameter in young `Dezful’ olive trees. Three irrigation regimes (40% ETcrop, 65% ETcrop and 100% ETcrop) were used. After irrigation treatments were applied, some of biochemical parameters including chlorophyll a, b, total chlorophyll, chlorophyll fluorescence and also chlorophyll ...

The objective of this study was to evaluate the stenting (grafted cutting) propagation of commercial pomegranate cultivars as scions on drought tolerant genotypes as rootstocks. The effect of drought stress on nine pomegranate rootstocks was analyzed. Cultivars including ‘Daneshgah 13’, ‘Daneshgah 32’ and ‘Daneshgah 8’ that were used as rootstocks showed the maximum drought tolerance among the ...

in order to evaluate the effect of zeolite application and selenium spraying on some physiological traits and grain yield in medicinal pumpkin (cucurbita pepo l.) under different moisture regimes, a study was conducted in a factorial experiment based on randomized complete block design with three replications during 2010 in takestan at gazvin province, iran. the three levels of irrigation facto...

determination of chlorophyll content and chlorophyll fluorescence has the potential needed to analyze the efficiency of photosynthesis in plants against environmental stresses, especially salinity, and its simplicity facilitates stress evaluation. in order to study the response of different photosynthetic characters to salinity stress at different sugar beet growth stages, two separate experime...

to comparison the photosynthetic parameters and leaf chlorophyll content and fluorescence of safflower (carthamus tinctorios l.) cultivars under salinity stress, a pot experiment was carried out as factorial based on completely randomized design with three replications in summer 2011 in university of yasouj. first factor included four salinity levels (zero, 75, 150 and 225 mm (formed as 20 to 1...

nickel and cadmium are heavy metals with some hazards for plant metabolism. the impacts of nickel chloride (0, 400 and 800 μm) in the presence of vitamin b complex (0, 30 and 60 ml from pharmacy commercial stock) and the impacts of cadmium chloride (0, 100, 200, 300, 400, 500 and 600 μl from 100 µm stock) in pot and cadmium nitrate (0, 100, 200, 400, 800, 1600 and 3200 μl from 100 µm stock) in ...
