高温贮藏对生态休眠期中国水仙的影响

目的]探究高温贮藏能否抑制中国水仙种球的物质消耗,延后中国水仙的花期。方法]以室温贮藏的种球和高温(30℃)贮藏处于生态休眠期的中国水仙3年生种球为试验材料,对比分析其重量、贮藏形态及定植后分蘖数、叶长、叶宽、花朵数、花朵开放时间等相关生长指标。结果]高温贮藏可缩小中国水仙种球贮藏前后表观形态差异,延长其生态休眠的进程;与室温贮藏相比,高温贮藏使中国水仙种球的观赏期延后近2个月。结论]该研究为中国水仙的抑制栽培提供了借鉴。

Effects of High-temperature Storage on Narcissus tazetta L.var.chinensis Roem.in Ecological Dormant

Objective]To explore whether the high temperature storage could inhibit material consumption during the ecological dormant time of Narcissus tazetta L.var.chinensis Roem.,and to postphone the flowering phase of N.tazetta.Method]With bulb stored at room tempera-ture and the three-year-old bulb at Ecological Dormant stored at high temperature(30 ℃)as the test materials,comparative analysis was car-ried out on bulb weight,storage form,tiller number,leaf length and width,flower number,flowering time and other correlated growth index. Result]High-temperature storage could make N.tazetta keep the same modality, and delay the progress of its ecological dormancy.Com-pared with room-temperature storage, high-temperature storage delayed the ornamental period of N.tazetta bulb for near 2 months.Conclu-sion]This research provided references for the inhibiting cultivation of N.tazetta.
