Exposure of mung bean (Vigna radiata [L.] Wilczek cv Jumbo) cuttings to low level red light inhibits dark-induced leaf abscission. A 12-hour daily light requirement for maximum inhibition of abscission was equally effective as a continuous red light treatment or shorter light-dark cycles. Transfer of cuttings from dark to light stopped the abscission process at the time of transfer. The available evidence suggests a light receptor located in the leaves with an abscission inhibitor translocated from lighted leaf to the abscission zone.
绿豆（Vigna radiata [L.] Wilczek cv Jumbo）插条暴露在低水平红光下会抑制暗诱导的叶片脱落。每天 12 小时的光照需求是最大限度抑制脱落的有效条件，与连续红光处理或更短的光暗循环效果相同。将插条从黑暗转移到光照下，在转移时停止了脱落过程。现有证据表明，叶片中存在一种光受体，具有脱落抑制剂从光照叶片转移到脱落区。
