Cereal Seed Germination under Anoxia
The great majority of seeds from higher plants fail to germinate under anoxic conditions. While the metabolic pathways operating during the aerobic process of seed germination are well described, there is only limited evidence concerning metabolic pathways operating under conditions of limited oxygen availability. This is despite the importance of carbohydrate availability for plant tolerance t...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
In Vitro Seed Germination and Seedling Growth for Salt Tolerance in Rice Cultivars
Six selected cultivars of rice namely BPT-5204, MTU-7029, CSR-30, Narendra Usar Dhan-3, Rajendra Bhagwati and Pusa Basmati-1 were screened for salinity tolerance on the basis of in vitro seed germination and seedling growth under different salt stress (02.5%) created by a salt mixture of NaCl, CaCl2, and Na2SO4 in 7:2:1 ratio. At 2% salt stress, germination was only observed in cultivars CSR-30...
متن کاملThe effect of exogenous silicon on seed germination and seedling growth of wheat cultivars under salt stress conditions
ABSTRACT- Seed germination and early seedling growth are critical stages for plants establishment and production, particularly under salinity conditions. Exogenous application of silicon (Si) can enhance germination as well as seedling growth. In this experiment, the effect of priming with Si (0, 0.75, 1.5 and 2.25 mM sodium silicate) on seed germination and seedling growth under NaCl (0, 100 a...
متن کاملEFFECTS OF NaCl TREATMENTS ON SEED GERMINATION AND ANTIOXIDANT ACTIVITY OF CANOLA (BRASSICA NAPUS L.) CULTIVARS
Effects of salt stress on germination, seedling growth and activity of antioxidant enzymes in leaves of six cultivars of canola (Brassica napus L.) were investigated on two F1 hybrids (Hyola401, Hyola330) and four open pollinated cultivars (Zarfam, Okapi, RGs003 and Sarigol). Seeds were germinated under various levels of salinity (0, 50, 100, 150 and 200 mM NaCl solutions). An increase in NaCl ...
