In this study, seven walnut populations (Rabor, Hanza, Sardoueih, Dalfard, Bidkhan, Dehbakri, and Baft) were selected from Kerman province and compared for drought stress tolerance. Water potential between 0 and -1.5 MPa was obtained by polyethylene glycol 6000 solutions. Germination percentage, leaf relative water content (LRWC), and growth parameter of seedlings diminished with increasing dro...

Drought cause yield loss of soybean production is the major reason to yield losing of soybean. To improve the germination and growth of soybean seeds under drought stress; We studied the effect of the single walled carbon nanotubes (SwCNTs) material in seed germination and the physiological changes occurred under drought condition, performed SwCNTs treatments in soybean (Zhonghuang 35) seeds at...

salvia genus has 58 annual and perennial herbaceous species in iran that 17 species are endemic and salvia sahendica boiss & buhse is one of them. in order to investigate the effects of drought stress caused by peg 6000 and salinity stress induced by nacl on germination factors of salvia sahendica, two experiments were carried out based on a completely randomized design with 3 replications. in ...

The adverse effects of salinity and PEG-induced water stress on growth of Matricaria chamomilla were assessed at the germination stage using osmotic solution of NaCl (0, -0.175, 0.358, -0.541, -0.716 MPa), and polyethylene glycol (PEG 6000) (0, -0.05, -0.1, -0.2, -0.3 MPa), respectively. Effect of NaCl salinity stress (0, 40, 80, 120 and 190 mM NaCl) at early growth stage of chamomile was also ...

salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

introduction: b. campestris is an old plant that commonly grows in arid and semi-arid areas. it has mucilage in the epidermal cells of canola seeds, a considerable variation in growth form and characteristics across the many cultivars. these species have in general, a flat root without an elongated crown, with stems that typically grow 30 to 120 cm tall. the leaves are large, soft, smooth or so...
