Abstract
Using the method of laboratory bioassay,the interference of the extracts from Azolla imbricata on the growth of rice was primarily studied.The results showed that the extracts with different concentrations had influences of different degree on the seed germination and seedling growth of rice.Extracts at concentrations of 250~4 000 μg/mL had no significant effects on rice seed germination;ethanol and aqueous extracts at concentration of 1 000 μg/mL could enhance the seedling root length and plant height significantlyby 27.32% and 9.15%,respectively;ethanol extracts at concentrations of 250~4 000 μg/mL and aqueous extracts at concentration of 4 000 μg/mL showed significant inhibition on rice seedling height,the same as aqueous extracts at concentration of 1 000~4 000 μg/mL on rice seedling root length;ethanol extracts at concentrations of 2 000~4 000 μg/mL and aqueous extracts at concentration of 4 000 μg/mL on seedling fresh weight per plant,the relative highest inhibition rates was 31.85%,14.28%,23.41%,16.49% and 10.94% respectively.Quadratic models were better for fitting the relationship between rice seedling root length,height,fresh weight per plant and ethahol extracts concentrations(root length: y=-0.215x2+1.541x+5.133,p=0.001;seedling height: y=-0.035x2-0.062x+5.574,p0.001;fresh weight per plant: y=-0.685x2+1.484x+100.0,p0.005),between seedling root length,height,fresh weight per plant and aqueous extracts concentrations(root length: y=-0.005x2-0.276x+7.012,p0.001;seedling height: y=-0.123x2+0.760x+4.490,p0.001;fresh weight per plant: y=-1.742x2+10.49x+89.27,p0.005).
