Abstract:
Using the way of natural cooling process，seven indexes correlating with cold resistance including malondialdehyde (MDA) content,cell membrane permeability(CMP)，soluble protein(SP) content，soluble sugar(SS) content，superoxide dismutase(SOD) activity，peroxidase(POD) activity and catalase(CAT) activity of aboveground and underground were monitored.The effects of low temperature stress on physiological characteristics of Cymbidium hybridum plantlets in vitro were determined and the capacity between aboveground and underground in improving cold-resistance for of Cymbidium hybridum were compared.The results showed that POD activity，soluble protein content and soluble sugar content significantly influenced the cold resistance and could be the indexes to identify the cold resistance in Cymbidium hybridum plantlets in vitro.The cold-resistance improvement of aboveground showed inconsistencies between different indexes to underground.The latter showed stronger ability of cold-resistance than the former.
