| 1 | 植物光合作用叶肉导度及主要限制因素研究进展显示文摘叶肉导度(g_m)被用来衡量CO_2从植物叶片气孔下腔到叶绿体羧化位点的传输效率,其主要受解剖结构和生化因素的调控。近年来,g_m的研究在光合作用领域受到普遍关注;光合速率的限制因素已不再简单地划分为气孔限制和非气孔限制,而需要从气孔限制、叶肉限制和羧化限制3个限制因素开展研究工作。该文分析了植物细胞壁、细胞膜、细胞质、叶绿体膜和叶绿体基质对g_m的调控机制,指出细胞壁厚度以及面向细胞间隙的叶绿体面积(S_c)是影响g_m的重要结构因素。阐述了水孔蛋白和碳酸酐酶参与的生化过程对g_m的调控机制。同时,对外界环境因素,如温度、光强、干旱、氮等对g_m的调控机制进行了总结。在此基础上,探讨了g_m与水力导度的耦合关系。最后对g_m研究中的科学问题进行了展望。 | 韩吉梅 张旺锋 熊栋梁 Jaume FLEXAS 张亚黎 | 2017 | 植物生态学报2017，41，8： | 26 |
| 2 | From leaf to whole-plant water use efficiency(WUE)in complex canopies:Limitations of leaf WUE as a selection target显示文摘Plant water use efficiency(WUE) is becoming a key issue in semiarid areas, where crop production relies on the use of large volumes of water. Improving WUE is necessary for securing environmental sustainability of food production in these areas. Given that climate change predictions include increases in temperature and drought in semiarid regions,improving crop WUE is mandatory for global food production. WUE is commonly measured at the leaf level, because portable equipment for measuring leaf gas exchange rates facilitates the simultaneous measurement of photosynthesis and transpiration. However,when those measurements are compared with daily integrals or whole-plant estimates of WUE, the two sometimes do not agree. Scaling up from single-leaf to whole-plant WUE was tested in grapevines in different experiments by comparison of daily integrals of instantaneous water use efficiency [ratio between CO2assimilation(AN) and transpiration(E); AN/E] with midday AN/E measurements, showing a low correlation, being worse with increasing water stress. We sought to evaluate the importance of spatial and temporal variation in carbon and water balances at the leaf and plant levels. The leaf position(governing average light interception) in the canopy showed a marked effect on instantaneous and daily integrals of leaf WUE. Night transpiration and respiration rates were also evaluated, as well as respiration contributions to total carbon balance. Two main components were identified as filling the gap between leaf and whole plant WUE: the large effect of leaf position on daily carbon gain and water loss and the large flux of carbon losses by dark respiration. These results show that WUE evaluation among genotypes or treatments needs to be revised. | Hipólito Medrano Magdalena Tomás Sebastià Martorell aume Flexas Esther Hernández Joan Rosselló Alicia Pou José-Mariano Escalona Josefina Bota | 2015 | The Crop Journal2015，3，3： | 9 |
