乙烯是一种释放乙烯利的作用剂,根据环境的变异,它影响葡萄内的酶的活力及矿质营养状态。提出了有关与内源激素相互作用的各种假设。乙烯利在不同程度上影响葡萄颜色的产生、浆果的成熟期及化学组成、浆果松离程度、营养生长、芽、繁殖、种子以及葡萄和葡萄酒的感官特性。许多因子,如品种、乙烯利喷布的浓度、时期和方法、PH、辅助剂、温度以及葡萄植株的水分状态等,都影响着葡萄对乙烯利的反应。 Ethylene is a release agent of ethephon, which, depending on the environment, affects the vitality and mineral nutrition of the grapes. Various assumptions about the interaction with endogenous hormones have been proposed. Ethephon affects the production of grape color to varying degrees, the ripening and chemical composition of berries, the degree of detached berry, vegetative growth, buds, reproduction, seeds and the organoleptic properties of grapes and wine. Many factors, such as variety, concentration of ethephon, timing and method, pH, auxiliaries, temperature, and water status of the grape plants, affect the response of the grape to ethephon.
