Description
Milkvetch (Astragalus adsurgens) is sown on > 1 M ha in China as a forage legume and to control soil and water erosion. It is drought-tolerant and has high herbage yield, wide adaptability and medium forage quality. However, fungal disease is a major factor affecting its persistence and productivity. Embellisia astragali is a highly virulent seed-borne pathogen which commonly causes stunt and root rot. The objective of this study was to characterize the impact of Embellisia astragali on the physiological status of milkvetch by monitoring changes through time in net photosynthesis, stomatal conductance and other parameters of milkvetch inoculated with the pathogen and to compare the data between resistant and susceptible varieties to identify the disease resistance physiological mechanism.
