Abstract
Change of CO2 concentration has significant influence on plant physiological development. In the present study,the effect of two CO2 concentration conditions( 400 μL/L and 800 μL/L) on the seed germination and seedling growth among five main host plants( Trifolium repens,Capsicum annuum,Chrysanthemum coronarium,Zea mays,Dianthus caryophyllus) of western flower thrip( Frankliniella occidentalis Pergande) were tested. The results revealed that the germination percentage,germination energy,germinationindex of these five host plants seeds all reduced along with atmospheric CO2 concentration elevated. The most reduction rate was found in T. repens,and the lowest reduction rate was D. caryophyllus. The seed vigor index of four plants degraded with atmospheric CO2 concentration rising except D. caryophyllus,and the peak reduction rate of seed vigor index was found in T. repens,which was up to 56. 1%. The root length of D. caryophyllus,C. annuum,T. repens increased along with elevated atmospheric CO2 concentration,and the increasing rate of D. caryophyllus' s root length was maximum( 66. 5%). The seedling root biomass /shoot biomass of the D. caryophyllus was significantly increased because of high CO2 concentration,but the root biomass /shoot biomass of other four plants seedling changed not significantly. The results would used to discuss the effect of CO2 concentration elevated on,and to research the feeding behavior of F. occidentalis under the rising atmospheric CO2 concentration.
