title: [Chlorophyll synthesis in cotyledons after gamma ray irradiation of black pine seeds].
abstract: 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.
