摘要
在苏南气候条件下,以欧洲水仙＂小矮人＂与＂塔希提＂2个品种的自繁种球为试材,探讨了不同时间低温（5~9℃）处理对欧洲水仙生长发育的影响与低温处理间鳞片与花芽的可溶性蛋白质与糖类的变化规律。结果表明：欧洲水仙种球在完成花芽分化后,早花品种＂小矮人＂在9月1日之前进行鳞茎冷藏处理,晚花品种＂塔希提＂在8月18日之前进行鳞茎冷藏处理,10月20日冷藏结束,可以实现元旦之前开花观赏;低温处理时间越长,开花越早,花葶越高。低温处理阶段,鳞片和花芽中的可溶性蛋白质含量随着低温处理时间的增加逐渐增加,且花芽中的可溶性蛋白质含量明显高于鳞片;鳞片和花芽中的可溶性糖含量均明显高于对照,且随着低温处理时间的增加,鳞片和花芽中的可溶性糖含量不断变化。该研究对欧洲水仙种球花期调控提供了理论和技术参考。
Taking the self-reproducing bulbs of Narcissus spp.varieties‘Young dawrf＇and ‘Tahiti＇as test materials,through different durations of cold treatment at 5-9 ℃,the changes of soluble protein and sugar indexes,the chilling effects for the growth and development of Narcissus spp.in South Jiangsu were analyzed.The results showed that early flowering‘Young dawrf＇and late flowering‘Tahiti＇bloomed normally before New Year＇s Day,with chilling‘Young dawrf＇bulbs before September 1st and chilling‘Tahiti＇bulbs before August 18 th after the completion of the flower bud differentiation,and the chilling end on October 20 th.The earlier the narcissus plant bloom and the higher the flower stem growth,the longer the cooling time was needed.As the increase of cooling time,the soluble proteins content both in flower bud and scale gradually raised.The soluble protein content was higher in flower bud than in the scale.The soluble sugar content was higher both in flower bud and scale than in the CK,and the content of soluble sugar in the scales and flower buds was also changing.It provided theoretical and technical reference for flowering regulation of Narcissus spp..
