Abstract:
Taking broccoli as test materials,the air conditions of 20%O2+20%CO2,50%O2+20%CO2 and 80%O2+20%CO2 were employed as treatments,natural air was set as control (CK).During storage at 20 ℃,the storage quality of broccoli florets and the relative expression of genes related to chlorophyll degradation were determined.To explore the effects of O2 on the degradation of broccoli chlorophyll in controlled atmosphere.The results of this experiment could provide a theoretical basis for the regulation of chlorophyll degradation under high O2 conditions.The results showed that with the increase of O2 ratio,the chlorophyll b reductase encoding gene (BoNYC〖STBX〗1〖STBZ〗),the chlorophyll encoding gene (BoSGR),the pheophytinase encoding gene (BoPPH),the pheophorbide a oxidase encoding gene (BoPaO),red chlorophyll degradation product reductase encoding gene (BoRCCR) expression levels and their relative expression peaks appeared earlier,which promoted chlorophyll catabolism and accelerated the yellowing process of broccoli.Among them,O2 promoted the gene expression of BoPPH in the process of chlorophyll degradation,which may be the main reason for promoting yellowing,SGR interacted the expression of BoPPH.
