复合型植物生长调节剂对骏枣果实糖积累及蔗糖转化酶活性的影响

Effect of Composite Plant Growth Regulator on Sugar Accumulation and Sucrase Activity of Zizyphus jujube cv. Junzao

研究复合型植物生长调节剂对骏枣果实糖积累及转化酶活性的影响。以3年生骏枣为试材,测定果实中总糖、葡萄糖、果糖、蔗糖的含量及酸性转化酶和中性转化酶活性。结果表明,骏枣果实生长曲线呈双"S"型。骏枣果实早期以积累葡萄糖和果糖为主,果实膨大期迅速积累蔗糖,到果实成熟时主要积累蔗糖。5 mg/L 5-ALA、10 mg/L GA3与15 mg/L CPPU的混合处理,与对照相比显著提高果实的糖含量,增强了转化酶活性。

To study the effect of composite plant growth regulator sugar on accumulation and transformation of the activity of jujube fruit agent for Chun.,3-year-old Junzao was taken as test materials,and the total fruit sugar,glucose,fructose,sucrose content and acid invertase and neutral invertase activity were investigated. The results showed that the growth curve of Jun jujube fruit was double‘S＇type. Jujube fruit in its early period was primarily in the accumulation of glucose and fructose-based,in the period of fruit enlargement was the rapid accumulation of sucrose,and in the mature period was primarily accumulation of sucrose. 5 mg / L5-ALA,10 mg / LGA3 compared with 15 mg / LCPPU mixing processing,and control significantly increased the sugar content of fruit and enhanced invertase activity.
