不同LED光源对一种新紫菜叶状体生长发育和光合生理的影响

Effects of different LED light sources on the growth,development and photo-synthetic physiology of the thallus of Neopyropia sp.

将一种新紫菜放置在5种不同的LED光源下培养,通过测量其各种数值,来探讨哪种LED光源会促进该种新紫菜的生长和光合作用。该种新紫菜叶状体的藻胆蛋白含量在蓝光和白光处理下的含量显著高于红光和绿光的处理。红光和白光处理下叶绿素a含量和类胡萝卜素含量显著高于蓝光与绿光处理下的含量。该种新紫菜在蓝光照射下最大相对电子传递速率(rETRmax)达到最大值,绿色最低,Fv/Fm无明显差距,NPQ的数值在蓝光下最高,橙光下最低。探索不同LED光对该种新紫菜叶状体生长发育和光合生理的影响,可以为未来开发利用这个新物种提供基本资料。

A new kind of laver(Neopyropia sp.)was cultured under 5 different LED light sources,and various values were measured to explore which LED light source would promote the growth and photosynthesis of this new kind of laver.The content of phycobilin in thallus of this new porphyra was significantly higher under blue light and white light treatment than under red light and green light treatment.The content of chlorophyll a and carotenoid under red and white light treatment were significantly higher than those under blue and green light treatment.Under blue light irradiation,the rETRmax reaches the maximum relative electron transfer rate(rETRmax),green light is the lowest,Fv/Fm has no significant difference,and NPQ is the highest under blue light and the lowest under orange light.Exploring the effects of different LED light on the growth and photosynthetic physiology of the thallus of this new species can provide basic information for the future development and utilization of this new species.
