研究了火棘果实发育成熟和贮藏过程中呼吸作用、相关氧化酶、营养成分的动态变化以及植物生长调节剂赤霉素(GA_3)和6-苄基腺嘌呤(6-BA)的作用,果实采收前2个月用80mg/kgGA_3喷施,刺激其呼吸强度升高,过氧化氢酶活性增强,可溶性糖、游离氨基酸含量提高及果胶、总酸度等下降。采用2个月用50mg/kg 6-BA喷施,则火棘果实呼吸强度下降,多酚氧化酶活性增强,能显著提高其在常温下的耐藏性。若采后用GA_3处理,刺激贮藏前期呼吸强度和多酚氧化酶活性增强。用6-BA处理,对整个贮藏期呼吸强度均有一定刺激作用,可保留较多的可溶性糖和维生素C。
The effects of respiration, relevant oxidase and nutrient contents during the development and maturation of Pyracantha fortuneana and the storage and storage of Pyracantha fortuneana were studied. The effects of gibberellin (GA_3) and 6-benzyladenine (6-BA) Two months before harvest with 80mg / kgGA_3 spray, stimulate their respiratory intensity increased catalase activity increased soluble sugar, free amino acid content and pectin, total acidity decreased. After spraying with 50 mg / kg 6-BA for 2 months, the respiration intensity of Pyracantha fortuneana decreased and the activity of polyphenol oxidase increased, which could significantly improve its storage stability at room temperature. After GA3 treatment, the respiration intensity and polyphenol oxidase activity were enhanced in pre-storage. With 6-BA treatment, the respiratory intensity throughout the storage have a certain stimulating effect, can retain more soluble sugar and vitamin C.
