Abstract
0.3 mmol L-1 salicylic acid (SA) was used to pretreat the leaves of pear, which were then inoculated with Physalosproa piricola Nose 3 days later and 3 days after inoculation all indexes were measured. The measurement was made every 3 days for 5 times. The result showed that the UFA, IUFA, chlorophyll content, photochemical efficiency (Fv/Fm), potential activity of PSⅡ (Fv/Fo), quantum yield of PSⅡ (ΦPSⅡ) and photochemical quenching (qP) of the pear leaves treated by SA and infected with P. piricola were increased, but their non-photochemical quenching (qN) decreased compared to those without treatment by SA. TEM observations showed that part of chloroplasts swelled and distorted, membrane fret bended and dispersed, starch grains decreased and symptoms greatly reduced after the treatment by SA.
