| 英文摘要 | Na+ distribution is one of the most important strategies for plant resistance to salt stress. The way of Na+ compartmentation in different aged leaves has been controversial, especially at the cell and sub-cellular level. The roles that Na+ and K+/Na+ play the key role in photosynthesis need to be further verified. In this study, using two cucumber cultivars Cucwnis sativus L. cv. zhongnong 8 (ZN8, relatively salt tolerant) and Cucwnis sativus L.cv. Jinchun 4 (JC4, salt sensitive) as experiment material, we analyzed the mode of ion compartmentation of Na+ in organelles in different aged leaves and determined which factors (the organelles' Na+ or K+/Na+) affect leaf photosynthesis, using high-pressure freezing and freeze-substitution, Ultrathin sectioning technique and X-ray. The main results: 1. The sub-cellular trends of Na+ accumulation was cell wall > vacuole > cytoplasm > chloroplasts; 2. The Na+ accumulation in cytoplasm and chloroplasts was similar in different aged leaves and in seedlings of different salt tolerance cultivars; 3. The K+/Na+ ratio is the main factor that affects the photosynthesis of the same aged leaves in our experiment. A weak capacity for ion compartmentation may be an important reason leading to salt sensitivity. |
