外源激动素和油菜素内酯对元宝枫结实产量和品质的影响研究

Effects of Exogenous Kinetin and Epibrassinolide on Seed Yield and Quality of Acer truncatum

  • 摘要: 以17年生元宝枫为研究对象,通过对其叶面喷施50 mg/L激动素和0.5 mg/L 2, 4−表油菜素内酯处理,分析外源激素对元宝枫翅果性状特征及种子性状、产量及品质的影响。结果表明:元宝枫叶面喷施2, 4−表油菜素内酯后,种子宽度和厚度显著增加,可溶性糖、蛋白质、油脂、神经酸含量均显著高于CK;激动素处理后种子可溶性糖、蛋白质、油脂、神经酸含量显著提高,百粒质量和单枝产量均显著高于CK。综合比较各项指标,2, 4−表油菜素内酯对元宝枫的促进作用略优于激动素。

     

    Abstract: Taking 17-year-old Acer truncatum stand as reserch object, effects of exogenous kinetin 50 mg/L and 0.5 mg/L 2, 4−epibrassinolide on phenotypic traits, seed yield and quality of A. truncatum were analyzed. The results indicated that the seed width and thickness increased significantly after foliar application of 2, 4−epibrassinolide, concentrations of soluble sugar, protein, oil and nervonic acid were significantly higher than CK; spraying kinetin induced significant increase in contents of soluble sugar, protein, oil and nervonic acid and hundred-grain weight and single branch yield were significantly higher than CK. According to analysis of various indicators, promoting effect of 2, 4−epibrassinolide on A. truncatum was slightly better than kinetin.
