| 摘 要： | 利用显微观察和DNA凝胶电泳等技术,研究在低温胁迫诱导下灰木相思组培苗细胞的凋亡和对低温环境的耐受性.显微结构观察表明,随着温度降低,细胞核出现明显的凋亡特征,证实低温胁迫可诱导灰木相思组培苗细胞凋亡,同时灰木相思组培苗对低温的耐受性是有限的,超过某一强度时,细胞会死亡. |
| 关 键 词： | 低温胁迫 灰木相思 组培苗 细胞凋亡 |

| Abstract: | Apoptosis and the tolerance of plantlets of Acacia implexa treated in vitro with cold stress were studied by microphotographics and total DNA agarose gel electrophoresis.It was found that the apoptosis characteristic of nucleus appeared while lowering the temperature.The results showed that cold stress caused apoptosis of the plantlets of A.implexa in vitro which had a limitation in the tolerance to cold stress. |
| Keywords: | cold stress Acacia implexa plantlet in tube apoptosis |
