In many plants, glycine betaine acts as an osmotic protectant and osmolyte. But some plants, such as the tomato, are not able to synthesize and accumulate this osmolyte. This study was designed to investigate the effect of exogenous application of glycine betaine in reducing drought stress in tomato plants. Water stress in three levels (0, 3 days and 5 days without irrigation) and glycine betai...

We conducted a glasshouse experiment as a  factorial in randomized study with six replications on pasture species of Schoenoplectus triqueter in Gonbad Kavoos University from 2012-2013. Treatments included height waterlogging in four levels (control, equal to the water surface, 10 cm below the water surface, 20 cm below the water surface) and waterlogging period over three levels (10, 20 and 30...

Considering the effect of salinity stress on the quantitative and qualitative traits of sugar beet genotypes, it seems necessary to study the response of genotypes obtained from breeding programs to salinity stress. For this purpose, 17 full-sib genotypes (derived from sibling crossing) with 7 different tolerant control under two salinity stress (electrical conductivity 17.36 dsm) and without s...

     Salinity is a major environmental factor limiting plant growth in natural ecosystems. Glycyrrhiza glabra is an important Fabaceae (perennial plant) that its root and rhizome extracts are used in food, health, medical and pharmaceutical industries. To assess the effect of methyl  jasmonate (MeJA) and salinity on licorice, an experiment was conducted as factorial based on completely randomiz...

The aim of this study was to evaluate the effect of different levels of soil moisture at irrigation time on root growth, yield and water use efficiency of greenhouse cucumber (Cucumis sativus L.), Yalda cultivar. The experiment was conducted in a randomized complete block design with six treatments and three replications in Isfahan Greenhouse Research Center in 2016. These experimental treatmen...
