in order to assess the effect of salinity constraint on some agro-physiological and biochemical traits in medicago sativa l., four alfalfa populations (tafilalet 1, tafilalet 2, demnate and tata), originated from mountains and oasis of morocco, were tested. the plants were grown under greenhouse conditions in pots filled with sand and peat under three salt treatments (0, 100 and 200 mm nacl). t...

Boron (B) is essential to growth at low concentrations and limits growth and yield when in excess. Little is known regarding plant response to excess B and salinity occurring simultaneously. In this study, two models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB), originally proposed to explain plant response to nutrients only, were modified to evaluate canola yield response to combined le...

to investigate effects of temperature and salinity different levels on germination parameters of german chamomile (matricaria chamomilla), an experiment carried out in complete randomized design as factorial with three replication in department of agronomy, college of agriculture on the university of guilan, in 2014. treatments were including temperature levels (5, 10, 15, 20, 25, 30 and 35 oc)...

water salinity and drought are the major abiotic stresses limiting turf grass growth. on the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as iran, are the restricting factors in developinglawn turf grasses. an experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (festuca aru...

the effects of drought and salinity stress on the growth and chemical compositions pennyroyal(mentha pulegium l.) plant were investigated. this experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (fc)) and five salt treatments with 0, 25, 50, 75 ...
