摘要
在干旱条件下,对不同糜子品种进行了全生育期抗旱性研究。结果表明,在干旱胁迫下各品种的有效分蘖、茎基长和穗质量受影响较大;株高、茎基粗、主茎节数与抗旱指数间呈负相关,但不显著;茎基长与抗旱指数间呈正相关,但不显著;穗长与抗旱指数间呈显著正相关,相关系数为0.966;穗质量与抗旱指数间呈显著负相关,相关系数为-0.990;宁糜16号表现出良好的抗旱性。
The different millet cuhivars were studied during the whole growth period of drought resistance. Under the drought stress, effective tillering, stem length and panicle weight of all varieties were affected. The plant height, stem thinkness, stem node number and drought resistance index were negatively related, but no significant; stem length was positively associated with drought resistance index, but no significant; spike length showed significant positive correlation with drought resistant index, the ratio was 0.966; panicle weight had significantly negative correlation with drought resistant index, the ratio was -0.990. Ningmi 16 showed better drought resistance.
