为研究柠条不同组织对黑豆幼苗光合特性的影响，采用2．5×10-2 g/mL、1．25×10-2 g/mL、6．25×10-3 g/mL和对照（CK）4种浓度柠条各组织水浸提液，培养发芽的黑豆种子。测定各处理植株的第3～4片真叶完全展开后的光合生理指标。结果表明：1）一定光强范围内，随着光强的增加，同一浓度处理下，叶片净光合速率、蒸腾速率均呈上升趋势；2）在一定光强下，对于同一处理，随着浸提液浓度的增加，叶片净光合速率、蒸腾速率均明显低于对照。3）柠条不同组织释放化感物质并作用于受体植物，抑制其光合作用。

In order to study effects of aqueous extracts of different Caragana tissues on soybean seedling photosynthetic characteristics,four aqueous extracts concentrations of Caragana,2.5 × 10 -2 g/mL,1.25× 10-2 g/mL,6.25 × 10-3 g/mL and CK(control treatment)were set to culture the germinative soybean seedlings.The photosynthetic characteristics of soybean were measured after the third or fourth leaf of soybean seedlings fully expanded in every treatment.Results:1)with increasing light intensities, the net photosynthetic rate and transpiration rate showed an obvious upward trend under the same treatment.2 )Soybean seedling leaf was affected on aqueous extracts from root,stem,leaf,soil of Caragana.And the net photosynthetic rate and transpiration rate were significantly lower than those of the control by the concentrations of aqueous extracts addition.3)It was suggested that the allelopathic substances from different tissues released and acted on receptor plants,inhibiting the photosynthesis.
