【摘要】 以 5个牡丹切花品种为材料通过瓶插观察 ,测定失水量与吸水量的差异 ,研究了牡丹切花品种的采后衰老特征、瓶插寿命与水分平衡的关系。结果表明‘百花丛笑’、‘朱红绝伦’及‘雪莲’不仅开放进程快 ,而且可达到最大开放程度 ,瓶插寿命为 5～ 6d ;‘玉面桃花’与‘天香湛露’瓶插寿命长达 8d ,但由于开放进程慢 ,并没有表现最长的观赏期。水分平衡值品种间存在差异 ,但变化趋势仍表现为上述两组 ,前 3个品种的水分平衡值前期较高 ,之后下降 ;而后两者则前期较低。水分平衡值与瓶插寿命未见直接的关系 ,但其变化趋势与花朵的开放进程关系密切更多还原

【Abstract】 This paper was to study the relationship among the postharvest opening progress, the vase life and the water balance of the cut flowers of Tree_Peony(Paeonia suffruticosa) cultivars. Five cultivars were investigated with the indexes of opening stages, the vase life and water transpiration, etc. The results showed that cultivars ‘Bai Hua Cong Xiao’, ‘Zhu Hong Jue Lun’ and ‘Xue Lian’ all exhibited fast opening pace and could be in full blooming with 5～6 days’ vase life. ‘Yu Mian Tao Hua’ and ‘Tian Xiang Zhan Lu’ lasted 8 days’ vase life, however, they did not show longer ornamental period than the prior 3 cultivars since their slower opening process. The changing trends of water balance differed among cultivars could be also grouped to 2 as mentioned above. The water balance values in ‘Bai Hua Cong Xiao’, ‘Zhu Hong Jue Lun’ and ‘Xue Lian’ began at high level and decreased dramatically in 2 days, then went up gradually during the late period of vase life, whereas it began at lower level and then go up and down in ‘Yu Mian Tao Hua’ and ‘Tian Xiang Zhan Lu’. The direct relationship between the water balance value and the vase life of tree peony cut flower was not found, but three was the close relationship between the change trend of the water balance value and the opening process of Tree-Peony flowers.更多还原
