Plant used different mechanisms to avoidance drought stress. This study was conducted to evaluate the role of exogenous application of glycine betaine in improving drought tolerance of Brassica napus. The study was performed on randomized complete block design with 3 replications. Different amounts of glycine betaine i.e. 0, 100 and 200 mM in combination with various irrigation periods i.e. 3, ...
Salinity stress is one of the main limiting factors for optimum agricultural productivity of safflower, Carthamus tinctorius L., in arid and semi-arid regions. It could leads to significant changes in plant biochemical, physiological, and growth traits. Salinity induced endogenous rise in jasmonic acid and its methyl esters (MeJA) has been reported. In the present study, effects of salinity str...
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...
Nitric oxide (NO) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. The research on the application of NO to postharvest preservation of flowers and fruits shows great promise in recent years. However, the physiological mechanism of exogenous NO to affect cut flowers is not very clear, and NO donor treatment protected plants from damage by increasing ...
Abstract The most important commercial use of gibberellin in horticulture is to improve the yield and marketability of table grapes. This experiment was conducted in order to evaluate the effect of different concentrations of gibberellic acid on yield components of five-year-old ʻAskariʼ seedless grapevines, based on a randomized complete block design. Gibberellic acid was sprayed on the folia...

• Bone mineral density (BMD) is used as an indicator of osteoporosis. BMD is measured and quantified by T-score, whose units are standard deviations relative to that of young, healthy adults (Young Adult Mean [YAM]). The International Osteoporosis Foundation (IOF) defines osteoporosis as a T-score of -2.5 or lower, i.e., worse. Severe osteoporosis is defined as a T-score of -2.5 or lower, and p...
