Abstract
Asarin Scandens Rose ('F499') is a perennial vine that is visually appealing, yet the salinization of the soil due to urban activity may reduce its potential as a landscaping plant. Our research utilized exogenous calcium to diminish the negative effects of salt stress on the growth of F499. Under salt stress, the application of 5 and 10 mM CaCl2 resulted in a considerable expansion of the leaf area, in addition to a heightened deposition of chlorophyll, thus improving the color of the leaves. Additionally, it was shown that F499's net photosynthetic rate (Pn), stomatal conductance (Gs), intercellular CO2 concentration (Ci), transpiration rate (Tr), proline and soluble protein levels all increased under the beneficial effects of CaCl2. Consequently, supplementation with appropriate amounts of exogenous calcium in urban saline soils is an effective way for plants to adapt to salt stress and maintain their ornamental value.
Asarin Scandens Rose （'F499'）是一种具有视觉吸引力的多年生藤蔓植物，但由于城市活动导致的土壤盐碱化可能会降低其作为景观植物的潜力。本研究利用外源钙来降低盐胁迫对F499生长的负面影响。在盐胁迫下，施用5和10 mM的CaCl2导致叶片面积的显著扩大，叶绿素沉积增加，从而改善了叶片的颜色。此外，在CaCl2的有利作用下，F499的净光合速率（Pn）、气孔导度（Gs）、胞间CO2浓度（Ci）、蒸腾速率（Tr）、脯氨酸和可溶性蛋白水平均有所提高。因此，在城市盐渍土中添加适量的外源钙是植物适应盐胁迫和保持观赏价值的有效途径。
