Effect of osmopriming on germination characteristic of Valeriana officinalis L. seed under drought stress
Journal Title: International Journal of Farming and Allied Sciences - Year 2017, Vol 6, Issue 3
Abstract
In order to study on effect of osmopriming on seed germination characteristic of Valeriana officinalis L. under drought stress, a factorial experiment in completely randomized design carried out with four replications and 2 treatments at the Research Laboratory of Shahrekord University, 2013. Four levels of drought stress (0, -2, -4, -6 bar) as main factor and four levels of priming (0, -4, -8, -12 bar) as secondary factor were considered. The results indicated that osmopriming, drought stress and their interaction had significant effect on germination percent, germination rate, mean germination time, rootlet length, and shootlet length. The osmopriming had an effect on increased germination percent, germination rate, and mean germination time. Meanwhile, the highest levels for the mentioned traits were obtained with treatment of -8 bar. Also, the drought stress made all germination traits to be decreased. And the highest levels were obtained with control treatment. Overall, regarding our research results, to achieve the highest levels for germination components in similar condition, treatment level of osmopriming as -8 bar is recommended with control level of drought.

Effect of gibberellic acid on growth and development plants and its relationship with abiotic stress
Gibberellic acid (GA3) is a plant hormone belongs to gibberellins. Plants produce low amount of GA3, therefore this hormone is produced by microorganisms. Exogenous GA3 on culture medium was used to increase height of...
Effect of 2,4-D and 2ip hormones on embryogenesis callus production and the effect of sucrose and concentrations of MS salts on somatic embryogenesis of date palm (cv. Medjool)
Somatic embryogenesis is one of the most common and effectual method for in vitro regeneration of date palms. In this study, production of embryogenesis callus in Medjool cultivar on high concentrations of 2,4-D (10, 3...
