| 摘 要： | 稻株受白背飞虱为害后 ,感虫品种 (TN1和汕优 63)光合作用速率和叶绿素含量下降率比抗虫品种 (N2 2 )明显 ;汕优 63和N2 2品种的二磷酸核酮糖 (RuBP)羧化酶的含量和活力均增加 ,TN1品种在为害 5d时RuBP羧化酶的含量和活力明显增加 ,而在为害 1 0d时显著下降 ;感虫品种受害后叶片光合产物滞留比抗虫品种多 ,即感虫品种光合产物向叶鞘、茎、分蘖和根等部位的转移量少于抗虫品种。 |

RELATIONSHIP BETWEEN PHOTOSYNTHESIS CHANGES IN LEAVES OF RICE PLANTS INFESTED BY WHITEBACKED PLANTHOPPER,Sogatella furcifera HORVATH AND ITS RESISTANCE |
|
| Abstract: | The results showed that after rice plants were infested by whitebacked plant hopper(WBPH),photosynthesis rate and chlorophyll contents in leaves of susceptible rice varieties(TN1 and Shanyou 63) declined obviously compared to those of resistant rice variety(N22).The contents and activities of ribulose-1,5-biphosphate(RuBP) carboxylaze increased in Shanyou 63 and N22,but in TN1 it increased after WBPH feeding for 5 days,and then,declined significantly after feeding for 10 days.Translocation of assimilates in leaves of susceptible variety TN1 was less than that of resistant variety N22 after WBPH feeding for 24 hours. |
