Abstract

The abscission zone in tomato (Lycopersicon esculentum (L.) Mill. flower pedicels is morphologically distinguishable prior to separation and is delineated by an indentation of the epidermis. Exposure of excised pedicels with the flower attached to ethylene results in abscission within 12 h and this can be accelerated by flower removal. Abscission of excised pedicels with the flower removed takes place in the absence of exogenous ethylene but this is delayed by pretreatment with aminoethoxyvinyl glycine, an inhibitor of ethylene biosynthesis. The data presented support the hypothesis that flower tissue is the source of an abscission inhibitor.

摘要

番茄（Lycopersicon esculentum (L.) Mill.）的离区在分离之前在形态上可区分，由表皮的凹陷界定。将带有花的花梗切除并暴露于乙烯中会导致在 12 小时内脱落，而去除花可以加速脱落。去除花的花梗切除后，即使没有外源乙烯也会脱落，但用乙烯生物合成抑制剂氨基乙氧基乙烯甘氨酸预处理会延迟脱落。所提出的数据支持花组织是脱落抑制剂来源的假说。
