| 摘要: |
| 在自然低温（1～4℃）侵袭后进行南洋楹抗寒生理指标测定，结果表明：南洋楹抗寒生理指标在参试家系间的变化不尽相同，各指标间的相关关系较复杂；进行抗寒性评价时，单一指标很难反映其实质；用主成分分析法进行抗寒性综合评价结果表明，综合抗寒力较强的家系有P16、Y6、P12、P14，较弱的家系有Y4、S3、N4和N5。 |

| Abstract: |
| The Index of physiological resistance to the cold of Paraserianthes falcataria were mensurated after being affected by naturally low temperature (1~4℃), the results showed that the change of the Index of physiological resistance to the cold were not complete homology among the families, the correlativity among index was quite complex, single index could not completely reflected substance. The result of synthesis evaluation by Principle component analytical method showed that four families including P16, Y6, P12 and P14 were appraised with highly strong resistance to the cold, and Y4, S3, N4 and N5 with relatively faintish resistance to the cold. |
