The influence of effective soybean seed treatment on root biomass formation and seed production

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...

Seed production in corn and soybean

Seed production is one of the least visible yet most important aspects of food and feed production. This part of the system is often taken for granted, even by the farmers who plant the seed. One of the reasons is that much of the seed in the United States is provided by the private sector, particularly for corn and soybean. Also, seed production is a technical process that requires in-depth kn...

Influence of Seed Ageing on Growth and Yield of Soybean

Effect of seed ageing on stand establishment, growth and yield of three soybean varieties was studied. Treatments consisted of three varieties viz. Shohag, Bangladesh soybean 4 and BARIsoybean-5 with four levels of seed ageing viz. 20, 12, 8 and 2 months aged seed. Seed germination and field emergence percentage decreased but electrical conductivity of seed leachate increased with increasing se...

Temperature, Moisture, and Seed Treatment Effects on Rhizoctonia solani Root Rot of Soybean

A STUDY ON SEED GERMINATION OF AVENA LUDOVICIANA AND THE EFFECTIVE FACTORS IN SEED DORMANCY BREAKING

Wild oat has two seeds in a spikelet that they have different physiological behavior in regard of  seed germiantion. The upper seed of spikelet is smaller and has deeper dormancy than the lower seed. The range of temperature for germination is  5˚C  to  25 ˚C  and optimal temperature is 15˚C. Both kinds of seeds showed the more  germination rate in low temperatures so that 5 and 10˚C are better...
