摘  要:
研究了不同浓度的氨气处理对绿萝叶片光合速率、蒸腾速率、气孔导度和气孔长宽比的影响。结果表明,在低浓度氨气处理下,绿萝叶片净光合速率、蒸腾速率和气孔导度整体提高,但气孔长宽比降低;在高浓度氨气胁迫下,绿萝叶片净光合速率、蒸腾速率和气孔导度整体降低但气孔长宽比升高,氨气的胁迫浓度为5.33 mg·m-3。

摘  要:
Under the different concentrations of ammonia,the changes of the photosynthetic rate,transpiration rate,stomata conductance and the ratio of length and breadth of stomata in ivy-arum's leaves were studied.The results showed that under low concentration of ammonia,the photosynthetic rate,transpiration rate and stomata conductance of ivy-arum's leaves were all increased,but the ratio of stomata's length and breadth decreased;under the high concentration of ammonia,the photo-synthetic rate,transpiration rate and stomata conductance were decreased as a whole,but the ratio of stomata's length and breadth increased.The stress concentration of ammonia was 5.33mg.m-3.
