effect 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...
Priming Effect of on the Enhancement of Germination Traits in Aged Seeds of Chamomile (Matricaria chamomilla L.) Seeds Preserved in Medium and Long-term Storage
Chamomile (Matricaria chamomilla L.) is a widely used medicinal plant possessing several pharmacological effects due to presence of active compounds. In order to study of seed priming effects on seedling growth of chamomile, an experimental design, based on randomized complete design with three replications was conducted under greenhouse conditions in Research Institute of Forests and Rangeland...
متن کاملRapid and enhanced germination at low temperature of alfalfa and white clover seeds following osmotic priming
Seeds of alfalfa (Medicago sativa) and white clover (Trifolium repens) were primed in 3 priming solutions [2% NaCl, 2% KNO3 and 300 g/L polyethylene glycol (PEG)] for 2 days at 20°C and their subsequent germination compared with that of untreated seed. Four replications of 50 seeds for germination and 25 seeds for emergence were arranged in a 2-factor factorial completely randomised design. All...
متن کاملChemical constituents of Coreopsis lanceolata L. and their physiological activities.
Petals from Coreopsis lanceolata L. were extracted in methanol and subjected to solvent-solvent partitioning to yield four fractions: hexane, diethyl ether, ethyl acetate, and aqueous. These fractions were screened using a 1,1-diphenyl-2-picrylhydrazyl radical scavenging assay and an active oxygen inhibition assay. The ethyl acetate extract contained the highest level of active components. Four...
متن کاملSeed Priming Increases Germination and Seedling Quality in Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia Seeds
This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...
