以4年生柚木的当年生半木质化嫩枝为插穗，5-9月的每月下旬扦插1次，同期测定插穗可溶性糖、全氮、可溶性蛋白质含量和过氧化物酶活性等生理生化指标，研究插穗生理生化指标对扦插生根的影响。结果表明：柚木嫩枝不同生长期的过氧化物酶活性、可溶性糖含量、全氮含量、碳氮比、生根率均有极显著差异（P＜0.01），可溶性蛋白质含量差异不显著（ P＞0.05）；碳氮比和生根率之间的正相关性较高。柚木嫩枝扦插的最适时期是7-8月。

The softwood cuttings propagation experiment using the half-lignified twigs of 4-year-old Tectona grandis L.f.was per-formed in the last ten-days of May,June,July,August and September.The variation of the soluble sugar ,total nitrogen,ratio of C/N, soluble protein,activity of peroxidase,etc,were studied in the same time,in order to discuss the impact of physiological and biochem-ical indices on rooting of cuttings propagation.The results showed that ,in different sprouting period ,differences of peroxidase ,soluble sugar,total nitrogen,ratio of C/N,rootage ratio are significant at 1%,differences of soluble protein are not significant;Positive rela-tivity between ratio of C/N and rootage ratio is quite high.The best time of softwood cuttings propagation for Tectona grandis L.f.in 4 years old is in July to August.
