Separation and Purification of Abscisic Acid and Its Catabolites by High Performance Liquid Chromatography

摘要: Numerous theories on the role of ABA as a plant growth regulator have been proposed, including, but not limited to, root gravitropism (Wilkins 1978, 1984; see Moore and Evans 1986), embryo bud dormancy (Addicott Lyon 1969; Walton 1980; Wareing 1978), stomatal closure (Raschke 1975). However, (1978) (1980) concluded that too little is known about events occurring during any physiological process to state unequivocally involved in its control. The best evidence, although still correlative, for involvement has obtained with experiments water stress. Detached or attached leaves will accumulate (usually 10 40 times found turgid leaf) upon imposition When given epidermal strips fed intact through transpiration stream, stomata close rapidly 1975; Davies Mansfield 1983). effect rather rapid compared protein synthesis, control α-amylase production barley aleurone layers. In this tissue inhibits gibberellin-induced synthesis α-amylase, which needed hydrolysis endosperm starch germination (Ho 1983, Jacobsen
