弯颈月季切花水剪试验

目的]探讨水剪对弯颈月季切花的保鲜效果,为长途运输后的弯颈月季切花提供有效的保鲜复苏方法.方法]分别从失水胁迫后的弯颈月季切花花枝基部水剪掉5、10和15 cm茎杆,以不水剪为对照,对比不同处理下月季切花的花头弯曲程度、鲜重、花朵直径、花朵寿命及水分平衡值.结果]在水中剪切掉弯颈月季切花大于或等于5 em花枝基部,瓶插1d内吸水量明显增加,弯颈处挺直,萎蔫柔软的花苞恢复坚实状态,花梗表皮由皱缩变光滑、饱满,花朵鲜重明显增加,花朵直径变化明显且呈正常的桔红色,花朵能正常开放至寿命结束,花朵平均寿命约7 d.结论]水剪大于或等于5 cm花枝基部,可确保弯颈月季切花茎杆基部的输导系统畅通,促使月季切花瓶插后能恢复正常状态,是弯颈月季切花有效的保鲜复苏方法.

Effect of cutting off neck-bending roses shoot in water on flower fresh-keeping

【Objective】The experiment was conducted to investigate the fresh-keeping effect by cutting off shoots of neck-bending roses in water to find an effective way to keep the normal quality of fresh flowers after long-distance transportation. 【Method】Neck-bending degree， fresh weight， flower diameter， flower life of neck-bending cut rose and water balance value were observed after cutting off 5， 10 and 15 cm shoot from flower shoot base. 【Result】After cutting off 5 cm or longer shoot from flower shoot base and placed in vase water for 1 d， water absorption obviously increased and bending neck became straight， withered and soft flower bud became solid and peduncle skin became smooth and plump， fresh flower weight evidently increased， flower became normal tangerine color with diameter changed greatly， and the average flower life was 7 days. 【conclusion】It was concluded that cutting off 5 cm or longer shoot from flower shoot base can make cut rose in vase keep well the normal quality of fresh flowers， and is an effective method to keep fresh of cut neck-bending rose.
