Abstract:

The paper studied the photosynthesis and chlorophyll fluorescence parameters of cassava seedling after Tetranychus cinnabarinus harm. The results showed that: compared with control，the Pn，Tr，Gs，Fm， Fv/Fm of cassava declined，Pn decreased to 2.57-7.62 umol/m2·s，Tr decreased to 0.13-1.28 mmol/m2·s ，Gs decreased to 0.020-0.176 umol.m2·s，Fm decreased to 0.031-0.241，Fv/Fm decreased to 0.037-0.11，while Ci and Fo increased，Ci increased to 3.51-158.5 μmol/mol，Fo increased to 0.023-0.09. There was no difference in the photosynthetic traits and parameters of chlorophyll fluorescence of four cassave varieties.
