- 摘要:
- 以拟南芥为试材，以0、50、150 Gy剂量60Co-γ辐照拟南芥种子，研究其对拟南芥植株生长发育的影响。结果表明：与对照相比，50 Gy辐照处理显著增加了拟南芥植株高度、莲座叶长度、角果长度、种子数量以及叶片光合色素含量；150 Gy辐照拟南芥的各项生长和生理指标显著降低，表明高剂量辐照处理抑制了拟南芥植株的生长。说明低剂量的60Co-γ辐照显著促进拟南芥植株的营养生长和生殖生长。
- Abstract:
- Arabidopsis seeds were irradiated with gamma irradiation at the doses of 0，50 and 150 Gy,respectively and the biological effects of gamma irradiation on plant growth and development were investigated.The results showed that 50 Gy gamma irradiation significantly increased Arabidopsis plant height，rosette leaf length，pod length，number of seeds，and content of photosynthetic pigments.While，gamma irradiation at the dose of 150 Gy obviously decreased the growth and physiological parameters，indicating that gamma irradiation at high doses inhibited Arabidopsis plant growth.Taken together，these results indicated that low-dose gamma irradiation significantly promoted the vegetative and reproductive growth in Arabidopsis plants.
