Abstract
alicylic acid,a plant induced-resistance activator,is able to alleviate the injury of pathogen to plant.In this study,0.3 mmol L-1 salicylic acid(SA) was applied on the leaves of pear,after 3 d Physalosproa piricola Nose was inoculated,and 4 d after inoculation all indexes were measured.The measurement was made every 3 days for 5 times.The results showed that compared with CK1,the 0.3 mmol L-1 SA could increase the activities of SOD,POD,CAT,APX,GPX and GR proline in leaves by 30.65%,25.36%,28.55%,21.11%,35.67% and 26.45%,respectively.The observation with TEM showed that in the pear leaves infected by P.piricola,Ca2+ was distributed on the inside of cell film,and on cytoplasm and some cell organs(such as chloroplast).The SA treatment indicated that inside the vascular bundle,secretion of germina could be seen,Ca2+ was mostly dotted on the outside of cell wall and between cells,which was similar to that in normal pear leaves,indicating that lower concentration of SA could reduce the damage of pear leaves by P.piricola.
