Abstract

Abstract: In order to improve seed yield and quality of wheat （Triticum aestivum L.） from the Qinghai-Tibet plateau, the suitable conditions for seed germination of wheat were explored. The seeds of wheat were separately treated with different concentrations （0.1,0.2,0.4 mol/L） of NaCl, Na₂CO₃ and HCl under constant temperature, in order to study the effects of different reagents on the seed germination rate. The results showed that, the seed germination of wheat was differently inhibited through different concentration of NaCl after soaking for 12 h. With the increasing of the concentration of NaCl, the seed germination rate of wheat increased firstly and then decreased. The effect of different concentration of Na₂CO₃ after soaking for 12 h on the seed germination of wheat was similar with NaCl. With the increasing of the concentration of Na₂CO₃, the seed germination rate of wheat increased firstly and then decreased. After soaking for 12 h, the different concentration of HCl had the different effect on the seed germination rate of wheat. When the concentration of HCl was 0.1 mol/L, the highest seed germination rate of wheat was 23.1% within 10 days. The germination of seed was inhibited when the concentration of HCl was 0.2 mol/L, and was obviously inhibited when the concentration of HCl was 0.4 mol/L.

Key words: wheat （Triticum aestivum L.）, NaCl, Na₂CO₃, HCl, germination characteristics, Qinghai-Tibet plateau
