60Coγ射线辐照对野牛草坪用性状的诱变效应
Mutagenic Effect of 60Co γ-rays Irradiation on Turf Characteristics of Buchloe dactyloides (Nutt.) Engelm
摘要
Abstract
[Objective] This study aimed to investigate the mutagenic effect of 60Co 7-rays irradiation on turf characteristics of Buchloe dac-tyioules (Nutt.) Engelm. [Method] Buffalo grass was irradiated by 60Co -γ-rays with five different radiation intensities (1200, 1400, 1600, 1 800, 2 000 Gy ) to determine the related turf characteristics and analyze the mutagenic effect of 60Co -γ-rays with different radiation intensities on buffalo grass. [ Result] Germination rates of buffalo grass irradiated by different radiation intensities of 60Cu γ-rays varied inconsistently, and the root length and bud length were shorter than the control; compared with the control, the height of irradiated seedlings was significantly smaller, and the number of tillers, plant height, leaf length and leaf width were shorter than the control; however, the stolon length, stolon width and number of stolon nods had no significant difference compared with the control. [ Conclusion] This study laid the foundation for determining the appropriate radiation intensity of 60Co -γ-rays and selecting useful mutants of buffalo grass.compared with the control. [ Conclusion] This study laid the foundation for determining the appropriate radiation intensity of 60Co -?-rays and selecting useful mutants of buffalo grass.关键词
