[Effects of light quality and germplasm on growth and effective ingredients of Dendrobium officinale germchit].
Effects of light quality and germplasm on the growth and effective ingredients of Dendrobium officinale germchit were studied. Under 8 light qualities (red, blue, yellow, green and three different red blue mix light), test-tube plantlets of different families (9 x 66, 17 x 30, 78 x 68) were used in the experiment to measure economical character and determine the content of chlorophyll, polysaccharides and total alkaloids. The results showed that light quality, germplasm and their interaction had a significant effect on the growth of D. officinale germchit. The maximal root length and height of seedling were obtained under red light, under blue light, the stem diameter was thickest and the content of total alkaloids were highest, the content of chlorophyll and polysaccharides of test-tube plantlets under red blue mix light were higher than that of other treatments. This work has laid a foundation for the high quality, low carbon and efficient production of D. officinale, and gives useful tips on production of high quality ingredients.
