蓝光和红光对菊花生长和开花的影响

Effects of Blue Light and Red Light on Dendranthema Growth and Flowering

蓝光光质下培育的菊花比自然光下培育的菊花叶绿素含量、净光合速率、叶片氨基酸总量、糖类含量分别提高２４．６％、３９．７％、３２．０％、８．９％。蓝光光质有利于菊花茎叶生长和侧枝产生，形成丰满株形，并能提前花期１２ｄ。

Growing Dendranthema under blue light induced increases of leaf chlorophyll, photosynthesis, amino acid and corbobydrate content compared to growing under natural light. The increments were 24.6%, 39.7%, 32.0% and 8.9%, respectively. Blue light benefits the growth of leaves and stem and the development of branches and chubby plant shape. The plants under blue light flowered 12 days earlier than that under natural sunlight.
