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...
Effect of Ultrasonic Extraction Regimes on Phenolics and Antioxidant Attributes of Rice (oryza sativa L.) Cultivars
Teh ultrasound-assisted magnetic stirrer was used as an effective extraction technique for teh evaluation of total phenolic contents (TPC) and antioxidant potential of ten Pakistani brown rice cultivars. For this purpose, ultrasonic (240W frequency 50/60 Hertz) assisted magnetic stirrer coupled with three solvents methanol, ethanol, and isopropanol in pure and aqueous fractions (80:20) were...
متن کاملSeed Germination Ecology of Echinochloa glabrescens and Its Implication for Management in Rice (Oryza sativa L.)
Echinochloa glabrescens is a C4 grass weed that is very competitive with rice when left uncontrolled. The competitive ability of weeds is intensified in direct-seeded rice production systems. A better understanding is needed of factors affecting weed seed germination, which can be used as a component of integrated weed management in direct-seeded rice. This study was conducted to determine the ...
متن کاملResponse of Germination and Seedling Growth of Pepper cultivars to Seed Priming by Plant Growth Regulators
In order to study the germination and growth of pepper seeds, a factorial experiment based on a completely randomized design with three replications was conducted. The first factor was consisting of five cultivars of pepper (Marquiza, Cadia, California Wonder, California Wonder 310 and California Wonder 300) and the second factor was gibberellic acid with three levels (0 as control, 250 and 500...
متن کاملEffects of different priming treatments and priming durations on germination percentage of parsley (Petroselinum crispum L.) seeds
The effects of different priming treatments and priming durations on germination percentage at different temperatures in parsley seeds were studied. The seeds were treated for 2, 4, 6 and 8 days with the PEG 6000 (–0.5 MPa, –1.0 MPa and –1.5 MPa), KNO3 (0.30 mol/L and 0.35 mol/L), Mannitol (0.50 mol/L and 0.60 mol/L) and hydropriming (12h, 24h, 36h and 48h) and unprimed (control). Germination s...
