Environmental stresses specially drought, play an important role in decreasing plant growth, particularly during germination in dry and semi dry area. To considering the effect of drought stress caused by polyethylene glycol on germination and characteristics of 2 spices of Sesamum indicum, we had done factorial and complete accidental plot with 4 treatments and 3 times repetition. Experimental...

in order to evaluate the allelopathic effects of white top (cardaria draba (l.) desv.) water extracts on corn and canola germination characteristics, an experiment was carried out based on crd design with three replications in agronomy research lab of yasouj university. treatments were included of 25%, 50%, 75% and 100% water extract (50 gr dm/l) of root, leaf and stem, inflorescence and whole ...

ecosystem pollution and weed resistance to herbicides have led researchers to pay more attention to natural herbicides. to examine allelopathic effects of liquorice, rosemary, chamomile and eucalypt on germination characteristics and early growth of wheat (triticum aestivum l.) and wild oat (avena fatua l.), a factorial experiment based on completely randomized design with 20 treatments and fou...

poor establishment of seedling due to both drought and lack of water is one of the most important problems in arid and semiarid regions such as iran. so, in order to evaluate the effect of lentil seed size on germination and seedling growth properties affected by drought stress, a completely randomized design with factorial arrangement and 3 replications conducted using two lentils genotypes (r...

this experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (triticum aestivum l.) and durum (triticum turgidum l.) wheats in seedling stage. a greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. different agronomic and physiol...

Lawns achieve environmental, functional, and aesthetical roles in urban environments. The objectives of this research were to assess the effect different salinity levels on Trichoderma isolates study spp. perennial ryegrass under salinity. T. harzianum (ThLem2017-01) atroviride (TaDP2019-01) had a higher mycelium growth rate than (TaDP2019-02) when low. In contrast, isolate at high superior res...

background: since most clinical treatments of persian children’s language impairments are based on either the therapist, clinicians’ experiences (mostly), or english language norms (sometimes), comparing two minor indices of speech quality, namely “mean length of utterance” (mlu) and “mean length of five phrasal utterances” (mlfpu) between different age groups of children, would be unequivocall...

chamomile (matricaria recutita) is a highly valuable medicinal and aromatic plant of asteraceae family and its anthodia used frequently in pharmaceutical and cosmetic industries. the aim of this study was the evaluation the effect of drought stress induced by polyethylene glycol 6000 (peg) on germination percentage, germination rate, plumule and radicle length of four improved cultivars of germ...

the inheritance of cold resistance was evaluated at the germination stage in crosses between seven rice genotypes as half diallel. analysis of variance indicated that there were highly significant differences among the genotypes, general combining ability (gca) and specific combining ability (sca) for percentage of reduction in radicle length (rl), percentage of reduction in plumule length (pl)...
