乙烯利和脱落酸对北五味子木脂素及苯丙氨酸解氨酶活性的影响

Effect of Ethephon and Abscisic Acid on the Lignans and PAL Enzyme Activity of Schisandra chinensis(Turcz)Baill

以北五味子为试材,在转色期分别用400mg/L乙烯利和1 000mg/L脱落酸(ABA)处理果实,研究乙烯利和ABA对北五味子木脂素及苯丙氨酸解氨酶(PAL)活性的影响。结果表明:转色期至成熟处理,对照果实总木脂素和PAL活性均呈增加的变化趋势,成熟期果实总木脂素乙烯利和ABA处理比对照分别提高11.08%和15.11%,处理间无显著差异,与对照差异显著;CK成熟期果实PAL活性为20.21U·h-1·g-1,乙烯利和脱落酸对提高北五味子果实总木脂素含量和增加PAL活性具有促进作用,乙烯利和ABA处理的果实PAL活性分别为22.09、22.36U·h-1·g-1,处理间差异不显著。

Taking Schisandra chinensis（Turcz）Baill as test material,the treatment of 400mg/L ethephon and 1 000mg/L ABA were done at veraison in order to study the effect of ethephon and abscisic acid on the lignans and PAL enzyme activity of Schisandra chinensis（Turcz）Baill.The results showed that control fruit total lignans and PAL activity showed a trend of increasing from verasion to mature processing,mature fruit total lignans of ethephon and ABA treatments were higher than that of controls by 11.08%and 15.11%.There were no significant differences between treatments and significant difference with control;Fruit PAL activity of CK in mature period was 20.21U·h-1·g-1,ethephon and ABA were 22.09U·h-1·g-1 and 22.36U·h-1·g-1.There were no significant difference between treatment.Ethylene and abscisic acid could promote to increase total lignanoids and the activity of PAL of Schisandra chinensis（Turcz）Baill.
