摘要
研究了叶面喷施不同浓度的5-氨基乙酰丙酸(ALA)对甜叶菊生长指标及叶绿素含量、总糖含量和产量的影响。结果表明:叶面喷施不同浓度的ALA均明显提高了甜叶菊的叶绿素含量、总糖含量和产量;与对照(清水)相比,0.10%的ALA叶面施用效果最佳,叶绿素含量、总糖含量和产量分别提高88.02%、0.40个百分点、33.62%。建议在实际生产中推广应用。
The field experiment was carried out to determine effect of foliar spraying 5-aminolevulinic-acid（ALA） on the growth, chlorophyll content index, total sugar content and yield of Stevia.The results showed that：spraying different concentrations of 5-aminolevulinic-acid significantly increased the chlorophyll content, total sugar content and yield of Stevia; in comparison with the control（water）, 0.1% of ALA had best effects, the chlorophyll content, total sugar content and yield of Stevia increased by 88.02%, 0.40%, 33.62%, respectively.0.1% of ALA was recommended to applicate in the actual production.
