MUT, Z. and H. AKAY, 2010. Effect of seed size and drought stress on germination and seedling growth of naked oat (Avena sativa L.). Bulg. J. Agric. Sci., 16: 459-467 Effects of seed size and osmotic stress on germination and seedling growth of five naked oat genotypes were investigated in this study. Oat genotypes were Mozart, CROA 60, Detvan, Eva 1 and AC Belmont. Small, medium and large seed...

BACKGROUND AND AIMS Most current thermal-germination models are parameterized with subpopulation-specific rate data, interpolated from cumulative-germination-response curves. The purpose of this study was to evaluate the relative accuracy of three-dimensional models for predicting cumulative germination response to temperature. Three-dimensional models are relatively more efficient to implement...

The effects of magnetic treatments on germination and the initial growth stages of triticale seeds have been studied. Germination and growth tests were carried out under laboratory conditions by exposing triticale seeds to 125 mT for different times (1, 10 and 20 min, 1 and 24 hour). The rate of germination was assessed by determining the mean germination time (MGT) and time required to germina...

Intense selection for specific seed qualities in winter oilseed rape breeding has had an inadvertent negative influence on seed germination performance. In a panel of 215 diverse winter oilseed rape varieties spanning over 50 years of breeding progress in winter-type rapeseed, we found that low seed erucic acid content and reduced seed glucosinolate content were significantly related with prolo...

kochia (kochia scoparia l. schard) is an annual, halophyte and drought resistant plant that can be irrigated with saline water and a valuable source for forage under drought and saline ecosystem. in order to evaluate the germination characteristic of kochia under different temperatures and salinity stress levels, an experiment was conducted at physiology lab of ferdowsi university of mashhad, i...

it is very important to find the best model to quantify seed germination rate on the response of temperature which it can be used in determination of cardinal temperatures. this study was conducted to evaluation nonlinear regressions models for description wheat (cv. morvarid) germination rate response to temperatures and water potentials. therefore, seeds germination rate were evaluated in tem...

ABSTRACT- This experiment was carried out during the growing seasons of 2010 and 2011 at the Agricultural Research Farm of Bu-Ali Sina University, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. Experiments consisted of two sets of treatment...
