Effects of Different Spectral LEDs on Seedlings Growth and Chlorophyll Content of Moringa oleifera Lam
摘要
Abstract
[Objective] To study effects of different light emitting diode (LED) light-supplement on seedlings growth and chlorophyll content in leaves of M.oleifera Lam.[Method] With the provenance of India Moringa seeds (M.oleifera PKM-1)as raw materials,different spectral conditions LEDs was used to supply light with 12 h/d (8∶00-20∶00) for it under the same external environment,and seedling growth and chlorophyll content were measured in leaves of M.oleifera Lam under different light-supplement treatment.[Result]M.oleifera Lam seeds germination rate by 4R1B LED treatment was higher than the control(CK),survival rate of three groups M.oleifera Lam seedlings after LEDs light-supplement were higher than CK.Plant height, stem diameter, dry weight of whole plant, dry weight of stem and leaf, total chlorophyll content of M.oleifera Lam seedlings treated by LEDs light-supplement were better than CK.Among of them , the growth promoting effect was the most significant of it treated by all red LEDs,plant height increased by 120.66%,stem diameter increased by 52.11%,whole plant dry weight increased by 52.35%,dry weight of stem and leaf increased by 33.57%,total chlorophyll content increased by 19.28%.[Conclusion] LEDs light-supplement treatment can significantly promote the synthesis of chlorophyll and leaf growth of M.oleifera Lam seedlings.关键词
