effect of free and symbiotic nitrogen fixing bacteria on seed and seedling produced seeds under deficit irrigation was conducted in laboratory and field experiments in 2006. in laboratory of karaj’s seed and plant research and certificate institute an experiment was conducted based on factorial in form of completely randomized design with four replications and in field’s of islamic azad univers...

Extended abstract Introduction: Seed germination is one of the first important and complex stages in the plant life cycle and is affected by many hereditary and environmental factors. Various factors affect germination and seedling establishment. Among these factors are the characteristics of the maternal plant (nutrition, genetics), seed treatment stage at harvest time, as well as environment...

In recent years the use of allopathic effects on weed management seems to have attracted many professionals. In order to investigate the effect of aqueous extracts of Yarrow (Achilla wilhelmsii L.) and Habek mint (Mentha longifolia (L.) Huds) medicinal plant on germination indices of plantain, two experiments were conducted in completely randomized design with three replications in 2014 in the ...

Gaining insights into the germination and emergence patterns of weeds as well as the factors which have an impact on these patterns is beneficial for weeds management programs. In order to investigate the effect of temperature, waterlogging and salinity on germination and emergence of common lambsquarters, three separate experiments were conducted, adopting a completely randomized design with f...

background and purpose: according to fao's report, lentil yield in iran is much lower than average yield in the world. this is due to low quality seedling production, low germination and emergence capacity, biotic and abiotic stresses and poor seedling establishment which was forced to looking for a way to enhance these components. seed priming is one of the strategy for increasing the rat...

This experiment was conducted as a factorial experiment based on a completely randomized design with three replications at two locations: Agricultural and natural resource center of Ardebil province (Moghan) and seed and plant certification and registration institute of Karaj in 2013. The treatments included: planting date in three levels (10-May, 25-May and 9-Jun), seed moisture content at har...

One of the important strategies for increasing germination speed and germination percentage, to produce high-quality seedling and plant optimal establishment is seed priming. In order to evaluate reactions of a lentil seed to priming duration and concentrations of the applied material as priming, a factorial experiment based on a completely randomized design with three replications was done in ...
