B型烟粉虱对番茄不同品种光合特征和防御酶活性的影响
Effect of Bemisia tabaci (Gennadius) B-Biotype on Photosynthetic Characteristics and Activity of Defense Enzyme in Different Varieties of Tomato
摘要
Abstract
[Objective] The objective of this study is to evaluate the selection of Bemisia tabaci B-biotype to different tomato varieties in the sight of physiological metabolism. [Method] An experiment was carried out at the artificial climate condition. The changes of the number of B. tabaci B-biotype, the value of photosynthetic parameter (I.e., Fv/Fm, Fv/Fo, Gs, Pn, Ci) and the defense enzyme (POD, CAT, PPO, LOX) activity on 9 species of tomato plant were comparatively studied by selection testing, respectively. [ Result] After sorting the 9 species of tomato plant by the number of the B. tabaci B-biotype, the descending order was arranged to be Huangshengguo (HSG)>Zheza 205 (ZA 205)>Zheza 203 (ZA 203)>Zheza 206 (ZA 206) = Zheza 809 (ZA 809) = Hezuo 903 (HZ 903) = Fenniang (FN)>Zhefen 202 (ZF 202) = Hongshengnv (HSN). Significant changes of the value of the photosynthetic parameter and the activity of the defense enzyme were observed in the plants HSG and ZA 205, but not in the plants ZF 202 and HSN, respectively. It indicated that the plants HSG and ZA 205 were stressed by the B. tabaci B-biotype feeding but not the plants HSN and ZF 202. As a result, two kinds of positive and significant correlations, I.e., the value change of the photosynthetic parameter and the number of the B. tabaci B-biotype, and the value change of light inhibition parameter (I.e., Fv/Fm) and the activity change of defense enzyme, were observed after 9 hours of selection testing. [Conclusion] Selection diversity of B. labaci B-biotype to different tomato varieties could be reflected by the value changes of photosynthetic parameter and the activity change of defense enzyme. The B. tabaci B-biotype exhibited the highest selection to the plants HSG and ZA 205 and lowest selection to the plants HSN and ZF 202. The number of B. tabaci B-biotype showed a positive significant correlation with the degree of stress of B. tabaci on tomato plant.关键词
