Abstract
After pretreatment the young grape plants with 50μmol/L JA and 100μmol/L SA solution,content of soluble protein,Glutathione(GSH) and activities of ascorbic peroxidase(APX)and Glutathione reductase(GR) in young grape plants went up at beginning and the lowered during 42℃ temperature stress,Ascorbic acid(ASA) content decreased during all stress period.Content of soluble protein,GSH,ASA and activities of APX and GR in young grape plants induced by JA and SA during heat stress were all higher than the control.The result showed that JA and SA could extenuate the changes of under heat stress.It was suggested that JA or SA enhances thermoprotection by similar mechanisms.
