描述

产品介绍 天然脱落酸((+)-Abscisic acid, S-ABA〕是一种具有倍半萜羧酸结构的植物天然生长调节物质,是植物体的“抗逆免疫因子”。1963年美国艾迪科特等从棉铃中提纯了一种物质能显著促进棉苗外植体叶柄脱落,称为脱落素II。英国韦尔林等也从短日照条件下的槭树叶片提纯一种物质,能控制落叶树木的休眠,称为休眠素。1965年证实,脱落素II和休眠素为同一种物质,统一命名为脱落酸。   脱落酸在衰老的叶片组织、成熟的果实、种子及茎、根部等许多部位形成。水分亏缺可以促进脱落酸形成。脱落酸在植物体内才再
别名 2-顺式,4-反式-5-(1-羟基-4-氧代-2,6,6-三甲基-2-环己烯-1-基)-3-甲基-2,4-戌二烯酸;(S)-(+)-脱落酸;休眠素;S-ABA;ABA;Dormin;;(S)-5-(1-Hydroxy-2,6,6-trimethyl-4-oxo-2-cyclohexen-1-yl)-3-methyl-(2Z,4E)-pentadienoic acid; ABA; Dormin; (S)-(+)-Abscisic Acid; S-ABA
生化机理 植物激素及生长调节剂,涉及几个生理机制,包括种子休眠,叶片脱落,气孔运动和植物应激反应。通过与多个细胞内信号系统复杂的相互作用,调控数百个植物基因的表达。
备注 脱落酸促进植物激素的天然异构体。
应用 脱落酸可以刺激乙烯的产生,催促果实成熟,它抑制脱氧核糖核酸和蛋白质的合成。脱落酸的生理功能有以下几种:
1. 抑制与促进生长。外施脱落酸浓度大时抑制茎、下胚轴、根、胚芽鞘或叶片的生长。浓度低时却促进离体黄瓜子叶生根与下胚轴伸长,加速浮萍的繁殖,刺激单性结实种子发育。
2. 维持芽与种子休眠。休眠与体内赤霉素与脱落酸的平衡有关。
3. 促进果实与叶的脱落。
4. 促进气孔关闭。脱落酸可使气孔快速关闭,对植物又无毒害,是一种很好的抗蒸腾剂。检验脱落酸浓度的一种生物试法即是将离体叶片表皮漂浮于各种浓度脱落酸溶液表面,在一定范围内,其气孔开闭程度与脱落酸浓度呈反比。
5. 影响开花。在长日照条件下,脱落酸可使草莓和黑莓顶芽休眠,促进开花。
6. 影响性分化。赤霉素能使大麻的雌株形成雄花,此效应可被脱落酸逆转,但脱落酸不能使雄株形成雌花。
