| 摘 要： | 百合辐射后鳞片扦插获得不定芽植株 ,在其生长发育过程中发现 :不定芽植株的花瓣、雄蕊、雌蕊及叶等器官都有变异。其中雄性器官变异率最高、类型最多 ,包括无花粉、花粉败育、雄蕊萎缩、雄蕊部分败育等类型。不同基因型的百合产生雄性不育变异类型有差异。从不定芽植株的突变率考虑 ,pollyana辐射诱发变异的适合剂量是 1～ 2Gy,王百合 (LiliumregaleWilson)及Romano的合适剂量是 1～ 3Gy。 |
| 关 键 词： | 百合 辐射育种 不定芽植株变异 雄性不育 |

VARIATIONS OF ADVENTITIOUS BUD PLANTS INITIATED FROM CUTTING SCALES OF IRRADIATED LILY |
|
| Abstract: | Adventitious bud plants were initiated from cutting scales of irradiated lilies.During adventitious bud plants growth and development,variation was observed on their petals,stamens,pistils and leaves.Stamens gave birth to the highest mutation rate and the most diverse variation,such as no pollen male sterility type,pollen abortion male sterility type,stamen collapse male sterility type and partial male sterility type, etc.Different male sterility types were found among the three lilies.Considering mutation rate of adventitious bud plants,1～2 Gy was suitable dose for `Pollyana'and 1～3Gy was proper to Lilium regale and `Romano'. |
| Keywords: | lily irradiation breeding variation of adventitious bud plants male sterility |
