| 摘 要： | 对搭乘神舟四号飞船的4个玉米自交系和相同来源对照的主要农艺性状进行了研究。结果表明:空间条件对不同自交系的出苗、成株和成穗情况,植株生长和出叶速率以及各农艺性状的影响不同;各自交系所有性状均出现双向变异,而且变幅和变异系数较大;各农艺性状间的相关性也有所变化。

| Abstract: | The main agronomic characters of 4 maize inbred lines,which were carried by ''Shenzhou IV'' spaceship were studied. The results showed that space condition had different effects on seedling emergence, survived and eared plants, the growth rate of plant height and the emergence rate of leaves in various stage, and almost all agronomic characters of various inbreds. All characters varied toward two directions, and their variation range and variation coefficient were all great. The correlations among all characters changed with no regularity. |
