The effect of kinetin on bud induction in the protonema of Funaria hygrometrica Sibth. has been studied. 1. Investigations on uptake and distribution of phenylalanine show that the availability of protein-building material is not the limiting factor during kinetin-induced differentiation. 2. Kinetin-induced bud formation in the protonemata is accompanied by decreased chlorophyll content. Changes in chlorophyll metabolism appear only after the simultaneous formation of numerous buds, indicating that this is a secondary effect of kinetin. 3. Under suitable conditions, a promotion of RNA metabolism by kinetin can be demonstrated. Analysis of moss protonemata at various times after germination shows a correlation between RNA content and kinetin-induced differentiation. 4. Under optimal growth conditions, no differences in RNA content could be found even after 48 hours of kinetin treatment.
已经研究了激动素对大灰藓原丝体中芽诱导的影响。1. 对苯丙氨酸吸收和分布的研究表明，在激动素诱导的分化过程中，蛋白质构建材料的可用性不是限制因素。2. 激动素诱导原丝体中芽的形成伴随着叶绿素含量的降低。叶绿素代谢的变化仅在大量芽同时形成后才出现，这表明这是激动素的次生效应。3. 在合适的条件下，可以证明激动素对RNA代谢有促进作用。对萌发后不同时间的苔藓原丝体进行分析，结果显示RNA含量与激动素诱导的分化之间存在相关性。4. 在最佳生长条件下，即使经过48小时的激动素处理，RNA含量也没有差异。
