Abstract:
Taking Dendrobium chrysotoxum as test material，the effect of different light intensity on the growth characteristics and the effective components of D.chrysotoxum were investigated.When D.chrysotoxum were grown under different light intensity by artificial shading with regulation shading network layer and height in six months, D.chrysotoxum growth index were determinated and collected to measure growth characteristics，amino acid polysaccharide，erianin and total phenolic content.The results showed that,at the light transmittance of 50%，D.chrysotoxum Lindl stem was the thickest，height growth rate was the fastest.Effect of different light intensity on chemical constituents of D.chrysotoxum was significant.In July，the content of total phenolic，erianin of D.chrysotoxum was the highest at light transmittance of 10%，were 0.945%，0.164 4%，respectively.In November，at light transmittance of 50%，polysaccharides content was the highest，up to 6.388%.Effect of different light intensity on growth characteristics，amino acid，polysaccharide，total phenols，erianin of D.chrysotoxum was significant.
