This current study focuses on the volative components which present in three different muskmelon cultivars Shannonghuangjin No.1,Sweet delight and Takami during fruit development.The fruit was sampled by SPME(Solid phase microextraction)combined with GC-MS(Capillary gas chromatography-mass spectrometry).The results indicated that volative components and contents of muskmelon differ in cultivars.156 components were separated from the three muskmelon cultivars.Aldehydes,alcohols,esters were the major constitu...
The physiological and biochemical changes under the low temperature stress were studied with Taiwandalongqie,94-1 zaochangqie and Jinongshijixingchangqie.After 9 days treatment,the chilling injury index,electrolyte leakage of leaves and the MDA content of Jinongshijixingchangqie were the lowest,the content of superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)were the highest,and the reduction extent of apparent quantum yield(AQY)and photochemical efficiency of photosystemⅡ(Fv/Fm)were the lowest,but ...
Under controlled conditions,the responses of cell membrane lipid and antioxidant system of zucchini(Cucubita pepo L.)seedlings to low temperature and weak light stress were investigated.The results indicated that membrane permeability,POD activity and the content of MDA increased,while SOD and CAT activities decreased in leaves of zucchini seedlings as the stress degree increased or the time prolonged.Low temperature stress showed greater influence than weak light on the determined indicators.
