Abstract
To study the toleration of different peanut cultivars to high temperature stress,Yuhua9719(sensitive to high temperature)and Jihua4(tolerant to high temperature)were used as trial material.After the treatment of 45℃ for 16 days in seedling stage,the metabolism related indicators such as biomass,photosynthesis and reactive oxygen species(ROS)were measured.The results showed that:(1)By comparing with control group,high temperature treatment made the plant height and dry weight of both cultivars decreased,the plant height of Yuhua9719 and Jihua4 reduced by 37.95% and 37.04%,the dry weight of Jihua4 reduced 21.17% while Yuhua9719 unchanged.(2)By comparing with the control,Fv/Fmof Jihua4 reduced 1.71%and Yuhua9719 unaffected.The high temperature made the water content and chlorophyll of Yuhua9719 increased 0.78% and 33.89% respectively.The carotenoids content of the two varieties decreased by 11.14% and 13.06% respectively,and the soluble protein content of the two varieties increased by 54.04% and 70.25% respectively.(3)After the high temperature treatment,MDA content of Yuhua9719 and Jihua4 increased by 39.30% and 36.30% respectively,SOD activities increased by 28.82% and 30.84% respectively,but the CAT activities unchanged.Free proline content of Yuhua9719 increased 811.23%.It showed that,the increase of free proline content in Yuhua9719 effectively maintained the water content in leaf tissues and reduced the damage to PSII.This might be the Yuhua9719's beneficial physiological responses to the high temperature.
