【摘要】 甜橙果实采后涂蜡可抑制贮藏初期的呼吸强度;能明显地降低抗坏血酸氧化酶和过氧化物酶活性;能导致果实内部乙烯和乙醇积累的增加;果皮细胞质膜透性和果实内部PG活性增大。涂蜡1个月,乙醇积累较对照高13％-14％左右,质膜透性增大11-12％,GP活性增大约20％。不同的蜡液对果实内部生化特性的影响不同。更多还原

【Abstract】 The respiration rate can be reduced 10.34-20.51 % during the early-period storage and the activity of ascorbic acid oxidase and peroxidase can be significantly inhibited by postharvest treatment with waxes in sweet orange. Due to sealing function waxes cause to accumulate the content of internal ethylene and ethanol, increase the plasma membrane permeability of peel cell and polygala cturonase (PG) activity. In the waxed fruit ethanol content increase 13. 15-14. 2% ,plasms membrame permeability and PG activity increaes 11. 06-42. 62% and 20. 4% respectively in comparison with the umwaxed control fruit after one month of storage. The effects of the different waxes on physiological and biochemical changes are different in sweet orange.更多还原
