摘要
甘蔗伸长期叶面喷施乙烯利表明,蔗茎伸长速度和酸性、中性转化酶活性上升都降低,20天后,蔗茎伸长速度和酶活性上升,并逐步超过对照。但新叶叶面积降低。乙烯利还能增加甘蔗茎粗和茎重,提高糖分含量。
Foliar spray of ethephon at the elongation stage of sugarcane decreased the rate of elongation of the stem and the activity of both the acid and the neutral invertasc after the application, but they began to rise twenty days after the treatment and surpassed the control. Leaf emergence, rate was raised and leaf area reduced by the application. Ethcphon was also found to increase the stem thickness and stem weight of sugarcane and to raise sucrose content of the stem.
