Effects of drought stresses induced by polyethylene glycol (PEG) on germination of Mongolian pine (Pinus sylvestris
Environmental stress, especially drought stress, can play an important role in the reduction of the plant growth stage, specifically duringgermination in arid and semi arid regions in Iran.. In order to study the effects of drought stress on germination indices in wheat cultivars, an experiment was conducted in factorial form, using a completely randomized design of four replications. In this e...
متن کاملEffect of drought-induced stress by PEG6000 on physiological and morphological traits of chickpea (Cicer arietinum L.) seed germination in order to assortment of drought tolerant cultivars
In this study, the reaction of germination and plantlet growth different chickpea cultivars (Arman, Azad, Binalood and Hashem) in relation to osmotic stress due to polyethylene glycol solution (-2, -4, -6 and -8bar) and control (distilled water) using factorial design in completely randomized with four replications was evaluated. In this study, there was a significant difference between the dif...
متن کاملشناسایی ارقام کلزا برای تحمل به خشکی از طریق شاخص‌های مرحله جوانه‌زنی و رشد گیاهچه براساس روش تجزیه به مؤلفه های اصلی
Drought stress can play an important role in limiting crop productivity and disturbing different stages of plant growth especially at seed germination in arid and semiarid regions. Breeding for drought tolerance at germination stage can enhance the number of seedlings, resulting in a higher yield of grain in rapeseed. In this research 32 cultivars of rapeseed were evaluated for drought toleranc...
متن کاملEffect of Seed Coating Methods on Germination Speed of Onobrychis sativa at Different Drought Stress Levels and Sowing Depths
Seed enhancement methods are applied to eliminate or decrease adverse environmental stresses effects and increase seed germination rate and vigor of rangeland plants. The aim of this study was to assess different methods of seed coating effects on germination speed of Onobrychis sativa at different sowing depths and soil moisture levels. The experiment was conducted at growth chamber to apply a...
متن کاملPositive effects of karrikin on seed germination of three medicinal herbs under drought stress
ABSTRACT- Improper seed germination is a serious challenge for medicinal herbs under drought stress conditions in semi-arid and arid regions. A new group of plant growth regulators known as karrikins have been proved useful to improve seed germination in some plants. In this regard, the effects of karrikin on seed germination and vigor of three medicinals under drought stress were examined. See...
