【Objective】The study confirmed the chorophyll content,relative membrane permeability and resistance to stripe rust of the different temperature typical wheats including Shaan 229,Xiaoyan 6 and NR9405.【Method】The resistant index to stripe rust,chorophyll content and relative membrane permeability were tested by the method of potted experiment,spectrophotometry and electric conductivity instrument in seedling stage.【Result】The results indicated that all of the tested varieties showed susceptibility to stripe rust.But the cooler typical wheat variety Shaan 229 showed longer latent period,less spos,shorter confinement,more leaf chorophyll content,less relative membrane permeability compared with the warmer one NR9405 after inoculation with CY29.This indicated that there is close relation between the resistance of wheat varieties to stripe rust and physiological characteristics.【Conclusion】These results show that the resistance to striperust of different femperahure typical wheat is closely related to its physiological characteristics.
