background and objectives: pomegranate, belonging to punicaceae family, is native of subtropical regions of iran and its neighborhood countries. iran has the richest germplasm resource of pomegranate and the first grade in cultivation area and production worldwide. physical and chemical properties of pomegranate cultivars vary in different developmental stages and have a large impact on the nut...

the use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (solanum tuberosum l.) micropropagation and adventitious shoot formation. three potato cultivars (agria, marfona and savalan cultivars) were examined for their growth response with medium containing four different levels of kno3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...

In this research, the response of shoot and root of two cultivars of soybean (Glycine max L. cvs Gorgan 3 & Williams) to mild and severe drought was evaluated in pot. Two weeks after of planting, three irrigation treatments including every day (as control), once in three (as mild stress) and five days (as severe stress) were used. The results showed that, stem dry weight, stem and root length, ...

Salinity is an environmental stress that limits growth and development in plants. Due to high salinity in Khuzestan soils it is necessary to identify cultivars with appropriate yield that are compatible with Khuzestan conditions. This experiment was done to evaluate three rice cultivars for salinity tolerance at seedling stage by measuring the absorption of sodium and potassium ions and the rat...

almond is one of the most important prunus species. most almond cultivars and genotypes are self-incompatible and some others are cross-incompatible. however, recently self-incompatible cultivars developed by breeding are available. therefore self-incompatible cultivars for pollination, fertilization and production require compatible pollen of other cultivars. in this regard the study of pollen...
