摘要

To determine the medium with the concentration of Na2SiO3 , the effect of different concentrations of Na2SiO3 on cold resistance of Cymbidium plantlets in vitro was studied. The results showed that Si enhanced osmotic regulation ability of Cymbidium evidently on cold resistance with increasing contents of free Pro, soluble sugar, soluble protein and decreasing contents of MDA. Compared with CK, osmotic regulation substances are accumulated rapidly. Free Pro, soluble sugar, soluble protein, MDA could be adopted as reference indices to evaluate capability of frost resistance of Cymbidium. By experiment we stated Na2SiO3 (3mmol/L) could relieve low temperature injury of Cymbidium plantlets in vitro. Mitigative effect was reduced with increasing concentration of Na2SiO3 .
