【摘要】 本文测定了不同组合甘蔗叶片的主要荧光参数。结果表明:田间对不同组合甘蔗暗适应的测定5min即可,测定部位以+2叶中上部为好。不同甘蔗组合间光能利用方面存在一定的差异,CP84-1198作为母本的两个组合,组合CP84-1198×川蔗57-416的Fm和Fv/FO明显高于CP84-1195×崖城90-33。具有相同父本的两个组合的光合特性相比,CP84-1198×崖城90-33的Fm和Fv/F0都明显高于粤糖91-976×崖城90-33。更多还原

【Abstract】 The main chlorophyll fluorescence parameters in different combinations of sugarcane were measured in field condition. The results showed that the minimum time for dark adaptation was 5 minutes, and the best part for measuring was somewhat above the middle of the leaf +2. There was difference in light energy utilization between two sugarcane combinations. The Fm and Fv/F in CP84-1198×Chuanzhe 57-416 were higher than those of CP84-1198×Yacheng 90-33, and those in CP84-1198×Yacheng 90-33 higher than those of Yuetang 91-976×Yacheng 90-33.更多还原
