为了研究切花衰老过程中的呼吸代谢和水分平衡，建立了一套完整的切花呼吸、蒸腾和吸水速率的测定系统。该系统保证了恒定的温度和恒定的相对湿度。利用该系统对两个不同衰老进程的香石竹切花品种的呼吸代谢和水分平衡进行了测定。综合考虑呼吸代谢与水分平衡的相互关系，对各品种的生理变化有了较全面的认识。特别是对于表现出跃变型的品种，本研究从宏观上充分估计了与萎蔫有关的细胞生理变化。【关键词】香石竹花，切花，呼吸速率，蒸腾速率，吸水速率，测定系统
A measuring system was constructed to measure respiration rate, transpiration rate and wateruptake rate of intact cut flowers in order to explain respiratory metabolism and water balanceduring senescence. The system assured both constant temperature and constant relative humidity. Respiratory metabolism and water balance of two cultivars of cut carnation flowers, each of which shows different senescence process, were measured with the system. From the results, a full understanding was gained for the change in physiological state if each cultivar after consideration ofmutual relationship between respiratory metabolism and water balance. Especially for the cultivar exhibiting climacteric behavior, physiological change in cells relating to wilting was sufficiently estimated from the macroscopic investigation in this study.
