To investigate the effects of saline stress on seed germination, ion distribution, and organic solutes changes of sunflower (Helianthus annuus L.), in the present study, seeds and 3-week-old seedlings were subjected to a series of external NaCl concentrations (5–200 mmol). The results showed that high salinity (200 mmol) remarkably inhibited the germination of seed and delayed germination time ...

Soil salinity and drought are the two most common and frequently co-occurring abiotic stresses constraining crop growth and productivity. Greenhouse pot experiments were conducted to investigate the tolerance potential and mechanisms of Tibetan wild barley genotypes (XZ5, drought-tolerant; XZ16, salinity/aluminum tolerant) during anthesis compared with salinity-tolerant cv CM72 in response to s...

phenotypic coefficient correlation is a relation criteria for traits. this coefficient can be used to differentiate insignificant traits of  varieties in selection programs. this survey was carried out with 10 breeding populations and susceptible controls in normal and stress conditions. the drought field was irrigated when plants reached wilting point. traits such as leaf length and width, pet...

in order to evaluation of morphological selection criteria for salt tolerance screening in wheat (t. aestivum l.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. salinity treatments involved 4 levels: s=1.3dsm-1 (control), 5, 10, 15 dsm-1 from calcium chloride and sodium chloride with 10:1 (na: ca ratio) and another facto...

salt stress is one of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. a greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (bamiand hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mm nacl) at the college of agriculture,shiraz university, shiraz, iran in 2008. plant dry weig...

Five cultivars of leaf lettuce (Lactuca sativa L. var. crispa) – Bergamo, Dubáček, Frisby, Lollo Rossa and Redin – were evaluated in two-year experiments carried out at the Faculty of Horticulture in Lednice (Mendel University of Agriculture and Forestry in Brno). Experiments were conducted in two trial years, 1998 and 1999; the lettuce was cultivated in three seasons: spring, summer and autumn...

in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...
