摘　　要：This study was conducted to screen and breed Azolla varieties with strong resistance.Four Azolla samples( CD,XT,HY,YZ) were collected from Hunan Province,and the growth characteristics such as propagation coefficient,temperature,light intensity,pH value and humidity were analyzed using artificial culture method.The results showed the four Azolla varieties all had the largest reproduction coefficients after cultured for 21 d,and the optimum culture conditions were temperature at 24-28 ℃,illumination intensity of 15 000-20 000 lx,pH 6.0,and humidity of 60%-80%.Among the four Azolla varieties,YZ has strong reproductive performance and high temperature resistance,and XT has strong acid resistance.This study was conducted to screen and breed Azolla varieties with strong resistance.Four Azolla samples( CD,XT,HY,YZ) were collected from Hunan Province,and the growth characteristics such as propagation coefficient,temperature,light intensity,pH value and humidity were analyzed using artificial culture method.The results showed the four Azolla varieties all had the largest reproduction coefficients after cultured for 21 d,and the optimum culture conditions were temperature at 24-28 ℃,illumination intensity of 15 000-20 000 lx,pH 6.0,and humidity of 60%-80%.Among the four Azolla varieties,YZ has strong reproductive performance and high temperature resistance,and XT has strong acid resistance.
