In order to determine the impact of thermo priming on germination of soybean seeds, an experiment was conducted as a completely randomized design with three replications. The factors of studied included different time thermo priming (control, 5 and 10 minutes) through the placing seeds were exposed to oven. The results showed that the effect of thermo priming was significant on germination perc...

Vegetable plug seedling has become the most important way to produce vegetable seedlings in China. This seedling method can significantly improve the quality and yield of vegetables compared to conventional methods. In the process of plug seedling, chemical fertilizers or pesticides are often used to improve the yield of the seedlings albeit with increasing concerns. Meanwhile, little is known ...

Vigour was measured using computer-aided analysis of digital images in six seed lots of Impatiens that differed in vigour but retained greater than 86% standard germination. Seed lots that differed in initial seed vigour were selected based on the commercially used Ball Vigour Index and vigour independently assessed using saturated salts accelerated aging tests. Digital images were captured fro...

the main objective of this study was using of canonical correlation analysis (cca) to find relations between 15 different variables of seed emergence and seedling growth related characteristics of seven important crop that were classified in three groups. the studied groups of variables were included physical characteristics (seed weight, seed length, seed density, water absorption and water co...

Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial design with eight blocks in May 2003. Each block consisted of a competition treatment (four gap sizes including zero) and a mowing treatment (mown...

Poor seed germination and early seedling growth associated with urea-induced soil ammonia volatilization are major constraints in the adoption of dry direct-seeded rice. To directly examine soil ammonia volatilization and its damage to seed germination and early seedling growth of dry direct-seeded rice when urea is applied at seeding, two Petri-dish incubation experiments and a field experimen...

Some biochemical activities in embryo or seedling of germinating rice (Oryza Sativa L.) seed were studied to explain the effects of suboptimum (20 C), optimum (30 C), and supraoptimum (40 C) temperatures on seed germination and seedling growth. It was observed that 40 C slightly speeded up seed germination but severely inhibited the growth of young seedlings, 30 C delayed germination compared t...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

Rhazya stricta. an evergreen poisonous shrub is rapidly invading large areas of rangelands in Saudi Arabia. A laboratory study was conducted to investigate the effect of its dry foliage leachate on seedling growth and survival of some range plants including R. stricta its self at different stages of seedling growth. Results indicated that seedlings were more susceptible to allelopathic effects ...
