Malformin and ethylene stimulate abscission of the primary leaves of Phaseolus aureus Roxb. in the dark, and abscission stimulation by both compounds is inhibited by indeleacetic acid and CO(2). Ethylene production by malformin-treated buds is stimulated within 4 hours. and up to 8 days, after treatment. Malformin-induced growth disturbances in P. vulgaris L. and abscission in P. aureus are considered mediated by ethylene. Although root curvatures of Zea mays L. are induced by both malformin and ethylene, and malformin is inhibited by CO(2), ethylene production is not stimulated by malformin. A role of ethylene in root curvatures induced by malformin is neither proposed nor disproved.
二甲弗林和乙烯在黑暗中刺激金雀花 Primary leaves 的脱落,而这两种化合物的脱落刺激都被吲哚乙酸和二氧化碳所抑制。二甲弗林处理的芽在处理后 4 小时内产生乙烯,并持续 8 天。金雀花中二甲弗林引起的生长紊乱和金雀花 Primary leaves 的脱落被认为是由乙烯介导的。虽然玉米和金雀花的根曲率都被二甲弗林和乙烯诱导,而二氧化碳抑制二甲弗林,但乙烯的产生不受二甲弗林的刺激。因此,不能提出也不能否定乙烯在二甲弗林诱导的根曲率中的作用。
