| 摘要: |
| 以半红期采收的赞皇大枣为试材，研究低温（0 ℃）以枣软化衰老的生理效应。结果表明，0 ℃低温可明显抑制大枣呼吸，维持低水平代谢；抑制多聚半乳糖醛酸酶（PG）活性，并抑制其前期果胶甲酯酶（PE）活性，但抑制效果不明显；可使枣维持较高的超氧化物歧化酶（SOD）、过氧化物酶（POD）活性，减少MDA累积。 |

| Abstract: |
| The effects on softening and senescence of the Chinese Jujube Fruit after they were harvested at half-red stage with low temperature were studied.The results show that:compared with 20 ℃ storage,low temperature (0 ℃) can remarkably inhibit respiration,slightly restrain polygalacturonase (PG) activity and pectin methylesterase (PE) activity in earlier stage;and preserve superoxide dismutase (SOD) activity and peroxidase (POD) activity,reduce the accession of MDA |
| Key words: Chinese Jujube (Zizyphus Jujuba Mill.) low temperature softening senescence |
