摘要
研究了绿竹链蚧不同危害程度对绿竹光合作用的影响。结果表明:与未受害比,轻度、中度、重度受害绿竹的SPDA值分别减少4.6%,12.4%,22.4%;净光合速率分别减少7.79%,16.39%,29.38%;暗呼吸速率分别提高了5.49%,26.67%,-7.39%;光呼吸速率分别提高了6.60%,30.08%,-11.56%;CO2补偿点分别提高1.15,1.48,2.04倍。不同受害程度对绿竹光合作用各项指标的影响均达极显著或显著水平。
The result of studies on the photosynthesis index of Dendrocalamopsis oldhami infested by Bambusaspis notabile to different degrees showed that compared with the uninfested ones, the SPDA value of D. oldhami with light, moderate and heavy damage were reduced by 4. 6%, 12. 4% and 22. 4% respectively;their net photosynthetic rates decreased by 7.79%, 16. 39% and 29. 38% respec- tively;their dark respiration rates increased by 5.49% ,26. 67% and -7.39% respectively;their photorespiration rates increased by 6. 60% ,30. 08% and -11.56% respectively; their CO2 compensation point increased by 1.15,1.48 and 2. 04 times respectively. There were significant or great significant differences in various photosynthesis indexes among D. oldhami infested to different degrees.
