The radiosensitivity of the greening system of Pinus nigra Arn. cotyledons has been studied in this paper. An exponential relation exists between the effect and dose for chlorophyll synthesis in the dark. Chlorophyll synthesis in the light roughly parallels that of chlorophyll synthesis in the dark. The restoration of chlorophyll was observed both in the light and in the dark. A stimulative effect of low doses of gamma radiation on chlorophyll synthesis was noticed. The radiosensitivity of chlorophyll a and chlorophyll b synthesis varied with the experimental conditions, suggesting that chlorophyll b synthesis might occur independently of chlorophyll a synthesis.
本文研究了黑松（Pinus nigra Arn.）子叶绿化系统的辐射敏感性。黑暗中叶绿素合成的效应与剂量之间存在指数关系。光照下的叶绿素合成大致与黑暗中的叶绿素合成平行。在光照和黑暗条件下均观察到叶绿素的恢复。注意到低剂量伽马辐射对叶绿素合成有刺激作用。叶绿素a和叶绿素b合成的辐射敏感性随实验条件而变化，这表明叶绿素b的合成可能独立于叶绿素a的合成而发生。
