Comparative Stem Photosynthesis between Desert and Mediterranean Legumes

虽然茎是第二重要的光合作用 器官，对茎光合作用知之甚少。 之甚少 已知茎光合作用适应或驯化 不同的气候条件。 比较叶的研究 不同气候下植物的光合作用 对于理解植物生存的机制至关重要 在不同的栖息地。 股骨柄的类似研究 光合作用，特别是在地中海和沙漠类群， 都需要理解茎的重要性 光合作用 本提案的目的是衡量 地中海和沙漠类群的茎光合作用 冬夏 这些结果的比较将测试 茎光合适应这些不同的生境。 此外，还建立了冠层茎光合作用的数学模型 将被开发。 该模型将能够预测 植物茎光合作用对植物多样性的重要性 不同的栖息地。 这项研究将大大扩展我们对 茎光合作用对植物的意义 这些信息 可以应用于各种植物成功的分析 环境. 此外，本研究收集的数据是 对于理解茎光合作用的重要性至关重要 对农业生态系统中豆类作物的生长有重要影响。

Although stems are the second most important photosynthetic organ, very little is known about stem photosynthesis. Little is known about adaptation or acclimation of stem photosynthesis to different climatic conditions. Studies of comparative leaf photosynthesis on plants from different climates have been pivotal to understanding the mechanisms by which plants survive in a diversity of habitats. Similar studies on stem photosynthesis, particularly in mediterranean and desert taxa, are required to understand the significance of stem photosynthesis. The objective of this proposal is to measure stem photosynthesis for mediterranean and desert taxa during the winter and summer. Comparisons of these results will test for stem photosynthetic adaptation to these different habitats. Furthermore, a mathematical model of canopy stem photosynthesis will be developed. The model will be able to predict the importance of stem photosynthesis to a diversity of species in a series of different habitats. This research will greatly expand our knowledge about the significance of stem photosynthesis to plants. This information can be applied to analyses of plant success in various environments. Furthermore, the data collected in this study are crucial for understanding the importance of stem photosynthesis to growth of legume crops in agroecosystems.
