摘 要：
以宁夏地区黑豆本土种为试验对象,采用基质培养法,研究了不同浓度R1(0.05000g/mL)、R2(0.02500g/mL)、R3(0.01250g/mL)、R4(0.00625g/mL)人工柠条林土壤水浸提液对黑豆幼苗的化感作用的影响。结果表明:随着光强的增加,同一浓度处理下,除了叶片胞间CO2浓度降低外,净光合速率、蒸腾速率均呈上升趋势;随着浸提液浓度的增加,叶片胞间CO2浓度增加,而净光合速率、蒸腾速率均显著低于对照。

摘 要：
Taking native species of local soybean as materials,by using medium culture method,the allelopathy of different aqueous extracts(0.05000,0.02500,0.01250,0.00625g/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.
