salinity is one of the important factors that reduce the growth and yield of crops in iran; however, determining appropriate methods for reducing its negative effects is important. in order to study the effects of nutritional condition of mother plant and bacterial biofertilizers seed priming on germination indices of wheat (triticum aestivum l.), in salinity condition, an experiment was conduc...

The physiological process of germination depends on several environmental factors such as temperature, water potential, light, nutrients and smoke. Water and temperature are determinant factors for seed germination. Both factors can, separately or jointly, affect the germination percentage and germination rate. The effect of temperature on germination and water potential on germination canoften...

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...

Unfavorable storage conditions, especially relatively high environment humidity and high storage temperature greatly affect the quality of corn seeds. The effects of temperature, environment moisture and length of storage on six maize hybrids were examined. For the purpose of investigating germination traits, total soluble proteins, leakage electrolytes and the activity of antioxidant enzymes i...

environmental stresses, such as salinity can play an important role in disturbing different stages of plant growth, development, and especially seed germination in arid and semiarid regions in iran. turf grasses are highly dissipation in areas associated with saline soils and/or saline irrigation water. in order to study the effects of salinity on turf grasses germination, an experiment was con...

In animal farming, anthelmintics are regularly applied to control gastrointestinal nematodes. There is plenty of evidence that also non-target organisms, such as dung beetles, are negatively affected by residues of anthelmintics in faeces of domestic ungulates. By contrast, knowledge about possible effects on wild plants is scarce. To bridge this gap of knowledge, we tested for effects of the c...

background and objectives: germination and seedling establishment are two critical and important stages during plants growing season. from seed technology viewpoint, germination refers to emergence and development from seed embryo, so that could produce normal seedling. many studies  have been done to determine germination cardinal temperatures and required thermal time for emergence occurrence...

Seed priming is one of the most important techniques used to improve seed germination under biotic and abiotic stresses. For this purpose, germination and seedling growth characteristics of primed seeds of Tall wheatgrass (Agropyron elongatum (Host.) P. Beauv) were evaluated under drought and low-temperature condition. A factorial experiment was conducted on the basis of randomized completely b...

The present study sought to evaluate the effect of different temperatures on germination and to determine cardinal temperatures (i.e., base, optimum and maximum) of Secale mountanum at temperatures of 3, 5, 10, 15, 20, 25, 30 and 35oC. Three nonlinear regression models (i.e., segmented, dent-like and beta) were used for quantifying the response of germination rate to temperature. The results sh...
