摘要
测定了四个甘蔗品种的茎伤流量、叶片游离脯氨酸、可溶性糖和叶绿素的含量四项生理指标。结果表明 :品种间伤流量差异显著 ;正常供水植株品种间游离脯氨酸含量、可溶性糖含量和叶绿素含量差异不显著 ,而受旱后品种间上述三项指标差异 (极 )显著。从四项指标来判断 ,粤糖 71 -2 1 0和粤糖 63- 2 37是较耐旱品种 ,而粤糖 57- 4 2 3是较不耐旱品种。甘蔗抗旱力与四项生理指标密切相关。
This experiment studied four physiological characteristics of four sugarcane varieties.The amount of bleeding is significantly different among varieties.The content of free proline,soluble sugar and chlorophyll is significantly different among varieties under soil drought stress conditions.The drought tolerance of Yue Tang 71 210 and Yue Tang 63 237 is stronger than that of Yue Tang 57 423.There is a close relationship between the drought resistance of sugarcane varieties and these characteristics.
