分析了乙烯利施用后3个甘蔗品种,新台糖16号(早熟)、桂糖11号(早中熟)和桂糖15号(中熟)节间4(未成熟节间)和节间8(成熟节间)蔗糖分累积的动态变化,对乙烯利催熟效应及增糖机制进行了探讨。乙烯利对甘蔗蔗糖分的影响因品种和节间而异,乙烯利显著提高未成熟节间的甘蔗蔗糖分,但对成熟甘蔗和(或)成熟节间的甘蔗蔗糖分影响不大。乙烯利能显著降低蔗汁还原糖分,而且对3个品种的成熟和未成熟节间都有影响,但以对未成熟节间的影响效应较大。乙烯利能显著提高纯度较低的未成熟品种或节间的蔗汁重力纯度。乙烯利的这些催熟效应在整个试验期都持续表现,而且是在不抑制甘蔗继续生长的条件下实现的。
The effects of ethephon application on three sugar cane varieties, including Xintai 16 (early maturity), Guitang 11 (early maturing) and Gui sugar 15 (maturing) internode 4 (immature internode) and internode 8 (Mature internode) sucrose content of the dynamic changes of ethephon ripening effect and sugar mechanism were discussed. The effects of ethephon on the sugar content of sugarcane varied with different varieties and internodes. Ethephon significantly increased the sucrose content of immature internode, but had little effect on the sugar content of sugarcane in mature sugarcane and / or mature internodes. Ethephon significantly reduced the sugar content of sugarcane juice, but also had an impact on the maturity and immature internodes of the three cultivars, but the influence on immature internode was significant. Ethephon significantly increased the purity and purity of the less pure immature or internode cane juice. These ripening effects of ethephon continued throughout the test period and were achieved without inhibiting the continued growth of sugarcane.
