摘　　要：对甘蔗不同芽位腋芽进行液体培养及内源激素的测定表明 :不同芽位间培养结果有差异 ,处于上部的芽位萌发生长快 ,处于下部的芽位萌发生长差 ,甚至萌发出根。腋芽内源激素呈有规律变化。IAA呈“U”型曲线变化 ,CTK ,GA1+ 3 随芽位下降含量降低 ,ABA则随芽位下降含量升高 ,芽位间各内源激素含量差异达极显著水平。Axillary buds of sugarcane were cultured in solution medium. Axillary buds at the upper nodes on the cane germinated quickly, while germination of the buds at the lower nodes was poor and even root germination occurred. Endogenous hormones exhibited regular changes. As the node location lowered along the sugarcane, the change in IAA content showed a U-shaped curve, the content of CTK and GA 1+3 decreased and ABA content increased.
