摘要
试验采用黑龙江省的10份光敏感杂交种及自交系作为试验材料,通过遮光处理的方法,对这些材料的发育进程、形态性状的光敏感性进行了研究。研究结果表明:玉米的9叶期-抽雄期及散粉期-抽丝期两个时期对光照比较敏感。同时遮光处理对玉米的株高、穗位高、叶片数和分枝数都有影响,但影响的程度不同。
The light-sensitivity of maize development and morphological characters was studied in this project using 10 inbred lines and hybrids selected from Heilongjiang province. The light was block 3 to 4 hours everyday from seeding stage to silking. The result showed that the two stages (from 9 leaf stage to head sprouting and from loose pollen to silking)of maize development were more sensitive to light than the other development stages. The result also showed the light -block played different roles on some major characters such as plant height、ear position、leaf number and bifurcation number.
