摘要
以多年生紫花苜蓿阿尔冈金(Medicago sativaL.Algonquin)为试验对象,以赤霉素(GA)、矮壮素(CCC)、多效唑(PP333)为试材,探讨了赤霉素、矮壮素和多效唑对紫花苜蓿生长的影响。试验结果表明:施用赤霉素提高了紫花苜蓿的生长速度,尤其是200mg/L浓度下喷施赤霉素能有效促进紫花苜蓿株高的生长。矮壮素则延缓生长速度,但提高了干物质积累量。
The experiment employed quadrennial Medicago sativa L. Algonquin as suDject, and gibberellin（GA）, chlormeqtiat chloride （CCC）, paclobutrazol （PP333）as the test material. In the application of the three types of plant hormone, the growth rate of alfalfa was totally different. The impact of GA, CCC and paclobutrazol on the growth of alfalfa was disscussed in this paper. The conclusions as follows： Application of gibberellic acid improved alfalfa growth rate. Especially 200 mg/L concentrations spraying gibberellic acid can promote effectively the alfalfa plant height growth. CCC can slow growth rate, but improve the dry matter accumulation.
