摘要: 本文研究了氮素添加(50 gN∙m−2∙a−1)对荒漠区濒危植物蒙古扁桃及其近缘种长柄扁桃和榆叶梅光合色素含量的影响。实验结果表明，氮素添加第3天开始蒙古扁桃叶绿素b含量显著增加(p < 0.01)，处理第6天，叶绿素a含量也显著增加(p < 0.01)，而且这种显著性差异一直维持在整个测定时间。添加氮素并没有引起长柄扁桃和榆叶梅叶绿素a含量显著增加(p > 0.05)，而其叶绿素b含量在长柄扁桃第一次喷施处理的第12天和第二次喷施处理的第10天才出现显著性差异(p < 0.01)；在榆叶梅叶绿素b含量在第二次处理的第10天才出现显著差异(p < 0.01)。氮素添加均引起3种植物类胡萝卜素含量的增加，这说明，氮素添加不仅影响植物氮代谢，而且也影响着其他物质代谢。
Abstract: The effect of nitrogen addition on photosynthetic pigments content of desert area endangered plant Prunus mongolica and its related species of P. pedunculata and P. triloba was studied. The experiment results showed that the content of chlorophyll b in P. mongolica increased significantly (p < 0.01) on the third day after nitrogen addition, on the 6th day of treatment, the content of chlorophyll a also increased significantly (p < 0.01), and the significant difference had been maintained throughout the measurement time. Nitrogen addition did not cause a significant increase in chlorophyll a content in P. pedunculata and P. triloba (p > 0.05), however, the content of chlorophyll b showed significant difference on the twelfth day after the first spraying treatment and the tenth day after the second spraying treatment (p < 0.01). There was a significant difference in the chlorophyll b content of P. triloba on the 10th day of the second treatment (p < 0.01). Nitrogen application caused the increase of carotenoid content of the three plants, which means that nitrogen application not only affects plant nitrogen metabolism, but also affects other material metabolism.
