摘    要
   本文通过应用不同的冷藏时间、水培界限、光照强度以及消毒与否等处理方法，初步探索冷藏处理对广西莪术种球开花的影响。结果表明，冷处理时间越长，种植后植株生长时间越短，开花越早。因此通过延长广西莪术种球的冷处理时间，可以缩短温室生长时间，根据具体需要达到调节花期。此外,较高温度下培养的植株的始花期、盛花期、凋花期均比处于常温短，而且开花率、开花质量均较为理想。可见温度在广西莪术的花期调控中具有决定性的作用。未发现光照强度对广西莪术的开花率有影响。

Effects of Rhizome Cold-Storage on Flowering of
Curcuma kwangsiensis

Abstract:  Flowering of Curcuma kwangsiensis rhizome were studied when hey were treated by cool –storing, culturing in Water and others. The results showed that: Curcuma kwangsiensis plant growed faster and blossomed more early with longer cool –storing time,so flowering period of Curcuma kwangsiensi could be regulated by controlling cool–storing time of Curcuma kwangsiensis rhizome.The different flowering period of the treated rhizome that were cultured at higher Temperature were shorter than that of the control ,and it had higher flower percentage and flowering quality Compared with the control . temperature  was Obviously the key to flowering period regulation of Curcuma kwangsiensis. Light intensity could not affect flowering rate of Curcuma kwangsiensis independently.
key words: Curcuma kwangsiensis ; Refrigeration; flower percentage ; Flowering period ;Wilting period
