摘要: 1989年我们对抗倒性不同的12个杂交玉米进行了解剖观察,发现地面上第三节间的茎外围维管束的长宽、维管束下部厚壁细胞的厚度。皮层厚度与田间倒伏率呈现显著的负相关,同一视野内维管束数目与倒伏率呈显著正相关。

Abstract: In 1989, we observed third internode of twelve corn hybrids with different anti-lodging property in microscope. The results indicated that the length and width of vascular bundle, the thiokness of thick wall cell of vascular bundle and cortex had significant negative correlation with the rate of lodging in the field. There was a significant positive correlation between the rate of lodging and the numbers of vascular bundle in a same field of microscope.
