Abstract:
Taking native species of local soybean as materials,by using medium culture method,the allelopathy of different aqueous extracts(0.05000,0.02500,0.01250,0.00625 g/mL) from soil of artificial caragana forest on soybean seedling were studied.The results showed that with the increasing light intensities,the net photosynthetic rate and transpiration rate except the intercellular CO2 concentration showed an obvious upward trend under the same treatment.The intercellular CO2 concentration increased by the concentrations of aqueous extracts addition,while the net photosynthetic rate and transpiration rate were significantly lower than those of the control.It was suggested that the allelopathic substances from soil of artificial caragana stands released and acted on receptor plants.
