【摘要】 柚木(Tectona grandis)为马鞭草科柚木属落叶或半落叶高大乔木。试验以4 a生柚木采穗圃的当年生半木质化嫩枝为材料,采用不同浓度IBA粉剂处理插穗后进行扦插,并对生根过程中插穗的过氧化物酶活性和可溶性蛋白质含量的变化进行研究,探讨柚木插穗生根与其生化指标的关系。更多还原

【Abstract】 Tectona grandis is a kind of defoliated or half-defoliated tall arbor,belonging to Verbenaceae Tectona.In this softwood cuttings propagation experiment,the half-lignified twigs of 4-year-old T.grandis were treated with exogenesis hormones of IBA powder in different concentrations in the last ten-day of July.The variation of activity of peroxidase and soluble protein in the cutting woods rooting process was studied,and the relationship between cutting woods rooting and biochemical indices was discussed.更多还原
