中文摘要：
为了明确24-表油菜素内酯（EBR）对茄子果实贮藏品质及抗氧化活性的影响,以‘布利塔’茄子为试材,研究了茄子果实冷藏过程贮藏品质和抗氧化活性相关指标的变化。结果显示：（1）与对照相比,EBR处理显著降低了茄子的冷害指数,延缓了果实贮藏过程中呼吸强度的上升和果面硬度的下降,明显抑制了茄子花萼变色,促进了可溶性总糖的累积,但对可滴定酸含量无明显影响。（2）EBR处理还诱导了茄子果实3种抗氧化酶（SOD、CAT和APX）活性的增加,并降低了H2O2含量。研究表明,EBR处理提高了茄子的耐贮性和贮藏品质,这可能与其维持了茄子果实较高的抗氧化活性有关。
英文摘要：
The present study aims to investigate the effect of 24-epibrassionolide（EBR）on the postharvest quality and antioxidant activity of eggplant fruit.With Brigitte eggplant fruits as material,the changes of chilling injury（CI）,quality and antioxidant activity of eggplants were measured.Results showed that：（1）EBR treatment reduced CI index,inhibited respiration rate,and maintained tissue firmness of experimental samples compared with the control samples.The changes of calyx discoloration and total soluble sugar content of the eggplants were also significantly preserved by EBR treatment.However,EBR treatment showed no significant effect on titratable acid content.（2）The activities of SOD,CAT and APX in eggplant fruits during storage were also promoting by EBR,as well as lower content of H2O2 content.These results suggested that EBR improves storability and quality of eggplant fruit during cold storage,which might be due to the higher maintenance of antioxidant activity.
