[目的]为了选择适合辽宁地区生长的速生、优良树种。[方法]用Li-6400便携式光合仪测定研究了3个引进树种苗期光合效率。[结果]小干松、黄松、班克松的净光合速率均表现出"单峰型"。3个树种的蒸腾速率有差异,其中小干松和黄松为单峰型,而班克松蒸腾速率为双峰型。10点时,3个树种净光合速率差异范围为43.57~58.74μmol/(m2·s),从大到小排序为黄松、小干松、班克松;蒸腾速率差异范围为15.68~21.92μmol/(m2·s),从大到小排序为小干松、黄松、班克松。在12点时,3个树种净光合速率差异范围为48.39~60.35μmol/(m2·s),从大到小排序为小干松、黄松、班克松;蒸腾速率差异范围为15.78~17.93μmol/(m2·s),从大到小排序为黄松、班克松、小干松。[结论]黄松、班克松、小干松这3个引进的树种均适应在辽宁地区生长。

摘  要:
[Objective]In order to select the suitable tree species for Liaoning area. [Method]We used the Li-6400 portable photosynthesis system to study the photosynthetic efficiency of 3 introduced species. [Result]The experimental results show that,Pinus contorta,Pinus ponderosa,Pnius banksiana photosynthetic rate showed single peak type. There are differences between the transpiration rates of 3 species,Pinus contorta and Pinus ponderosa are single peak,while Pnius banksiana transpiration rate for two-peak pattern. The 10 am.,3 species difference range of net photosynthetic rate is 43. 57- 58. 74 μmol /(m2·s). Transpiration rate difference range is 15.68-21.92 μmol/(m2·s). In the 12 am.,3 species differences range of net photosynthetic rate is 48. 39- 60. 35 μmol /( m2·s). Transpiration rate range is 15. 78-17. 93 μmol /(m2·s). [Conclusion]The results showed that 3 species are suitable for growing in Liaoning area.
