不同环境因素对唐菖蒲发芽及叶绿素含量的影响

目的]找出最适合于唐菖蒲（Gladiotus huhridus Bort）生长发育的光照长度.方法]以唐菖蒲红颜佳人品种为试材,通过控制光照时间、温度、湿度来观察唐菖蒲的发芽情况及叶片中叶绿素含量变化.结果]强光照和长日照有利于唐菖蒲发芽;适当短日照（8 ～ 10h）处理能够加速唐菖蒲叶片生长;发芽最适温度在20～25℃,适宜湿度是44％ ～ 46％;在整个生长阶段,叶绿素含量呈现出“降低-升高到峰值-下降至稳定”的趋势;同时,适当遮阴有利于光合产物的增加.结论]该研究可为唐菖蒲的规模化生产提供数据参考和理论支持.

Effects of Different Environmental Factors on Sprouting and Chlorophyll Content of Gladiotus huhridus Bort

Objective] The aim was to find out the very suitable illumination length for grow and development of Gladiotus huhridus Bort.Method] The sprouting status and chlorophyll content of Gladiotus huhridus Bort were investigated by controlling light duration,temperature and humidity.Result] The stong light and long-day was beneficial to sprouting of Gladiotus huhridus Bort,and proper short-day （8-10 h）facilitated its lamina development.The best temperature for the sprouting of Gladiotus huhridus Bort was 20-25 ℃,and humidity was 44％-46％.During the whole vegetative growth,the chlorophyll content of Gladiotus huhridus Bort demonstrated the trend of reducing-rising to peakdropping to stabilization.At the same time,proper shading benefited for the accumulation of photosynthate.Conclusion] The study provides data reference and theoretical support for a large scale production of Gladiotus huhridus Bort.
