Abstract

The effect of seed priming on six WHEAT cultivars was investigated using Urea, NaCl and PEG 6000 as OSMOPRIMING agents and tap water and distilled water as HYDROPRIMING agents on emergence rate, germination percentage and base temperature of germination. Each OSMOPRIMING agent was included of five osmotic potential levels (-4, -8, -12, -16 and -20 bar) , three temperature levels (10, 15 and 20°C) and two time levels (12 and 24 hours) but HYDROPRIMING treatments were included of above mentioned temperature and time levels. In each solution and each cultivar the best combination of applied levels on the base of seedling emergence rate was selected and compared with other solutions and check (unprimed) treatment. In four cultivars Alvand, Sardari, Mahdavi and Chenab, urea OSMOPRIMING had the most significant increase on seedling emergence speed, final germination percent and seedling vigour index. In Chamran cultivar OSMOPRIMING with NaCl had the best results and in Pishtaz PEG solution was the best priming alternative. In cultivars Alvand and Mahdavi HYDROPRIMING treatments not only had no increase on measured factors but also significantly reduced final germination percent and seedling vigour index. In other cultivars except Sardari HYDROPRIMING has become apparent similar check treatment. Correlation among speed of emergence and germination percentage of the best priming treatment in all cultivars was significant. Also in another experiment the best OSMOPRIMING treatments in all cultivars caused higher germination speed at lower temperatures (ranging from 1°c to. 12°C) and generally reduced base temperature of germination by almost 1.3°C compared to control. It is concluded that seed priming treatments with urea solutions may serve as an appropriate treatment for advancing seedling emergence speed and germination uniformity of the cultivars studied.
