Effect of BTH treatment on physiological characteristics and sensory quality of ‘Yujinxiang'muskmelon

The effects of BTH ( benzothiadiazole) treatment were studied on physiological characteristics and sensory quality of “Yujinxiang”muskmelon.The influence rules were analysed by the detection of fruit firmness, soluble solids content ( SSC) , malondialdehyde ( MDA) , intact cell membrane rate, ethylene release amount, respiratory intensity and sensory qulity.The results showed that BTH treatment slowed down the falling rate of hardness and SSC and accumulated rate of MDA.The respiratory intensity of fruits was obviously inhibited by BTH treatment, the ethylene release amount was lower than control sample during storage, the peak value was 46.08%of control sample.The change and trend of sensory qulity was consistent with physiological characteristics from BTH treatment.The sensory qulity of“Yujinxiang”muskmelon was maintained by BTH treatment.
