A major problem of arid and semi-arid regions is environmental stresses like salinity and drought. To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The experimental treatments included different salinity levels of NaCl (0, 50, 100, 150 mM) and five drought levels by PEG (0, 10%, 15%, 20% and 25%) with three rep...

Selection indices provide useful information to breeders who usually base selection on means and ranks. Knowledge on selection criteria for improving tef grain yield is very limited. Accordingly, the objective of this study was to develop selection criteria for improving tef grain yield through indirect yield component selection via a selection index. Different trait combinations along with thr...

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...

selenium is a metalloid that it is antioxidant characteristics is proved for humans, animals and plants. however, some plants are known as hyper accumulators for selenium and sometimes seems to be useful for growth of some plants. in this paper, we have studied the effect of different selenium concentrations on growth and morpho-physiological characteristics of spinach. seeds of spinach were ge...

Shoot tips from actively growing, greenhouse maintained plants of Kalanchoe blossfeldiana were cultured in vitro for shoot proliferation and root initiation on Murashige and Skoog (MS) basal medium supplemented with NAA and BA, both in concentrations of 0.00, 0.50, 1.00 and 2.00 mg l-1. Results showed that the maximum plantlets height (7.012 cm), node number (4.516), root number (8.860) and roo...

in order to study the response of coriander medicinal plant to salt stress, two experiments were conducted for germination and vegetative stages. this study was carried out as a factorial experiment based on completely randomized design with three replications. the treatments were salinity at five concentrations including 0, 25, 50, 75 and 100 mm nacl. response of coriander seeds germination in...

abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...
