| 摘 要： | 通过大田和盆栽试验研究了光质及光照时间对银杏叶黄酮和内酯含量的影响。结果表明:长波段的光(如红光)不利于黄酮和内酯类物质的积累而有利于植株的生长;短波段的光不利于生长但有利于黄酮和内酯类物质的积累。光质也影响银杏叶光合速率、PAL活性和相对生长量的大小。光照时间对银杏叶黄酮和内酯类物质含量、PAL活性无显著影响,但对植株的光合速率和相对生长量有显著的影响。

| Abstract: | Effects of light spectrum and photoperiod on contents of flavonoid and terpene in leaves of Ginkgo biloba L.were studied based on the field experiments and pot experiments.Light spectrum affected the contents of flavonoid and terpene,the photosynthetic rate,PAL activity,and relative stem growth.Long wavelength such as red light did not favour the accumulation of flavoniod and terpene,but promoted the growth of Ginkgo biloba.Short wavelength increased the accumulation of flavoniod and terpene.However it decreased the growth of Ginkgo biloba.Photoperiod had no significant effects on the content of flavonoid and terpene in leaves of Ginkgo biloba.Short light period did not favour the photosynthetic rate and relative growth,while long light period was favourable.The results from this research provided some bases for the management of Ginkgo biloba plantations. |
