in order to study the interaction allelopathic effects of wheat, barley and wild mustard on seed germination and seedling growth, this investigation was conducted in 2009 in two separate experiments. allelopathic effect of four aqueous extracts (0, 2.5, 5 and 10%) of wild mustard on wheat and barley germination was evaluated in the first experiment, based on two randomized completely designs (r...
About 10 percen of lands around the world under crops planting are affected by salinity. Therefore, comprehensive researches have been conducted to minimize the harmful effects of salinity in agriculture. The purpose of this study is examination of the Mmethyl jasmonate effect on reducing the effects of salinity in germination and vegetative stages of the basil plant.For the methyl jasmonate t...
In order to investigate the effect of pretreatment of chitosan biological compounds on seeds of soybean (Glycine max L. cv. Williams) under salt stress conditions, a factorial experiment was conducted, adopting a completely randomized design with three replications at Shahed University in 2015. Factors examined included the combination of chitosan at three levels (0, 0.25 and 0.5 the weight-vol...
seed germination is the most sensitive growth stages of the plant to salinity stress. seeds of many species produce a jelly-like layer called mucilage upon exposure to water. the purpose of this study was to determine the role of mucilage in increasing salinity tolerance of lallemantia ibrica. seeds of this plantcontain mucilage that can be used to treat some diseases such as neurological, live...

تاثیر هیدروپرایمینگ بر ویژگیهای جوانهزنی و رشد گیاهچه گلرنگ (Carthamus tinctorius L.) تحت تنش خشکی
Priming is an effective method to improve seed viability that might be resulted to increase of seed germination percent and germination rate under stress conditions, such as drought stress. So, in this research the effect of seed priming on seed germination characteristics of safflower were evaluated under drought stress. A factorial experiment based on completely randomized design (CRD) with t...
regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
Cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. In present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°C on 12 rice cultivars (including Champa Yasouj, Gerde, Lenjan Askari, Kaamfirouz, Kohsar, Shafagh, Domsiya Mamassani, Dular, Gharib, Hasan saraei, Mosa Tarom and 304)...
to study the effect of salinity stress on seed germination and seedling growth of four medicinal plants, nigella sativa l., cannabis sativa l., trigonella foenum graecum and cynara scolymus l. an experiment was conducted in the botany laboratory of islamic azad university, birjand branch. a completely randomized design (crd) with 3 replications was used as separately for each species. treatment...
Double direct-seeding for double rice cropping is a simplified, labor saving, and efficient cropping system to improve multiple-crop index and total rice production in central China. However, poor crop establishment of direct-seeded early rice due to chilling stress is the main obstacle to wide spread of this system. A series of experiments were conducted to unravel the effects of pre-sowing se...
