黑龙江省水稻品种芽期抗旱性及形态指标筛选研究
A Study on Drought Resistance and Screening of Morphological Indicators at Germinating Stage of Rice in Heilongjiang Province
摘要
Abstract
150 g/L PEG -6000 was used to induce water stress, and the effect of water stress on morphological indicators at germinating stage of rice in HeiLongJiang Province was studied. The results showed that the germination power, germination rate, seedling length, root length, root number, dry seedling weight of rice decreased under water stress, the dry root weight and coleoptile length showed inconsistent performance in different varieties, Dongnong425 ,HaO4 -29,Longjing21 had strong drought resistance. The seedling length,root lengt, dry seedling weight, germination rate, coleoptile length could be used as the main indicators of access of drougth resistance at the germinating stage of rice.关键词
