摘要
以银杏叶为材料,采用叶圆片法,探讨了外源糖类、植物生长调节物质对叶绿素降解和叶绿素酶活性的影响,结果表明0.02 mol/L蔗糖或葡萄糖在叶绿素降解初期能够显著提高叶绿素酶活性,10-7mol/L的6-苄基腺嘌呤能够延缓叶绿素降解的速率,并使叶绿素酶的活性维持在较高水平。
The discs of Ginkgo biloba leaves are incubated with sugar and plant growth regulator solutions in order to investigate the effects of those substances on chlorophyll degradation and chlorophyllase activities. The results showed that 0.02 mol/L sucrose or glucose could stimulate the chlorophyll activity at the initial stage of chlorophyll degradation, whereas 10^-7 mol/L 6- benzylaminopurine could retard chlorophyll degradation and maintain the chlorophyll activity at higher level.
