tent of ca. 5% of fully hydrated plants for a period of three weeks. During desiccation experiments the plants continued net emerd photosynthesis at a maximal rate until their relative water content (RWC) dropped to 60%. Net photosynthetic gas exchange of plants with only 10% RWC was still positive. Photosynthetic rates, however, decread during the drying process more rapidly than did the respiration rates. During rehydration, plants previously kept dry (5% RWC) for short periods (up to 24 h) regained net photosynthetic capability only when their RWC reached about 35%.
