| 摘 要： | 以不同剂量的60Co γ射线对‘铁骨素’建兰、‘十八学士’建兰、‘长汀’墨兰3种国兰成熟植株进行辐照,对各处理植株的新长幼芽、假鳞茎、花期、植株形态等进行观测。结果显示：在10～50 Gy辐照剂量范围内,受照植株成活率随剂量的加大下降,而辐照效应却增强。不同品种的国兰耐辐射能力有所差异,‘长汀’墨兰＞‘铁骨素’建兰＞‘十八学士’建兰;同一植株不同器官组织,不同发育阶段的耐辐射能力也有所不同,成熟假鳞茎＞幼芽＞花芽;植株形态变异一般只在VM1代的幼芽上有所发生。3种国兰成熟植株辐射诱变适宜的处理剂量为16～18Gy。 |

| Abstract: | The mature plants of three varieties of Chinese Cymbidium, including Cymbidium ensifolium 'Tiegusu', Cymbidium ensifolium 'Shiba Xueshi' and Cymbidium sinense 'Changting', were irradiated by 60Co γ-rays at different doses, and the irradiation effects of treated plumules, pseudo-bulbs, florescence and plant morphology were observed . The results showed that the survival rate of irradiated plants decreased as the doses increased within the range 10Gy to 50Gy. In addition, irradiation endurance of 3 varieties was Cymbidium sinense ‘Changting’＞Cymbidium ensifolium ‘Tiegusu’＞Cymbidium ensifolium ‘Shiba Xueshi’. Analogously, the irradiation endurance of tissues and plant at different developmental stages was mature pseudo-bulbs＞plumules＞blossom buds. Plant morphological variation was found only in the plumules of the VM1 generation. The results showed that the suitable irradiation dose for the mature plants inducement of 3 varieties of Chinese Cymbidium was determined within the range 16 Gy to 18Gy. |
