Abstract
The growing speeds of trunk diameter,stem height and shooting length in two year pear trees and pear seedlings,infected by Stem Grooving Virus(SGV),and three endogenous hormones of pear seedlings infected were assayed in this paper The results showed that the growth of inoculated plants with SGV decreased significantly,compared with the free virus ones Tthe growing speeds of trunk diameter,stem height and shooting length of two year pear trees with SGV decreased by 65%,58% and 51%,respectively,and stem diameter and height of the inoculated seedlings decreased by 11 7% and 13 5%,respectively Three endogenous hormone contents in the infected plants,including indole 3 acetic acid (IAA),gibberellic acid(GA 3) and cytokinins(CTK),were all obviously lower than those in the healthy ones during growing period The contents of IAA,GA 3 and CTK in pear seedlings with SGV reduced by 15%,19% and 59%,respectively These results also suggested that the poor growth might be closely related to the sharp decrease of three endogenous hormones after being infected by Stem Grooving Virus

Claim · model-written summary
The authors suggest the poor growth of infected pear plants may be closely related to the sharp decrease of three endogenous hormones after stem grooving virus infection.
