Seeds of alfalfa (Medicago sativa) and white clover (Trifolium repens) were primed in 3 priming solutions [2% NaCl, 2% KNO3 and 300 g/L polyethylene glycol (PEG)] for 2 days at 20°C and their subsequent germination compared with that of untreated seed. Four replications of 50 seeds for germination and 25 seeds for emergence were arranged in a 2-factor factorial completely randomised design. All...

Water deficit is a common and major constrain for agricultural production in arid and semi-arid parts of the world like Iran, to the extent that it might threaten the nation’s food security in years to come. Seed germination is a crucial growth stage that is often affected by environmental stresses, including drought. This study investigated the effects of four levels of water potential (i.e. 0...

In order to study the effect of seaweed extract and nano-ZnO on germination characteristics of tomato seed, a factorial experiment was conducted based on a randomized complete block design. Preliminary germination and seedling growth tests were performed to determine the best concentration of seaweed extract and nano-ZnO. Experimental treatments included three levels of drought stress (0, 2- an...

To study the effects of halopriming and hydropriming in overcoming salt and drought stress in corn (Zea mays L.),two experiments were separately conducted at Shahrood University of Technology. Seed treatments consisted ofcontrol (untreated seeds), soaking in distilled water for 32 h (hydropriming), and soaking in 50 mmol solution ofCaCl2 for 16 h (halopriming). Germination and early seedling gr...

Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under salinity stress. The effect of different treatments (Gibberellins 50 mgl-1, 2% CaCl2 and hydroprimig in 24 hours) was evaluated on total germinat...
