Abstract:
The effect of ultraviolet B (UVB) irradiation on the drought resistance of luffa was studied with the ‘Tianwei No.1’ luffa as material,in order to provide an economical and effective method for improving the drought resistance of luffa plants.The results showed that under drought stress,the luffa plants irradiated by UVB maintained a high net photosynthetic rate，a high electron transfer activity,and a lower content of reactive oxygen species.UVB irradiation could reduce the transpiration rate without affecting photosynthetic carbon assimilation,thereby maintaining a higher soil water content under drought treatment.In the case of the same soil water content,UVB irradiation could also maintain high net photosynthetic rate,prevent the blocking of electrons transfer,thereby reduced the generation rate of reactive oxygen species,consequencely prevented the cells from suffering severe oxidative damage.
