摘要: 以白凤水蜜桃为材料,研究了冷藏条件下包装和钙处理对果实成熟和软化过程的影响。结果表明:钙处理能明显抑制果实乙烯合成,降低果实的呼吸强度,推迟果实呼吸高峰的出现。抑制了果实PG活性的升高及软化速度。并能抑制组织电导率的升高,保持细胞膜结构的完整性,且对延缓组织的衰老过程具有一定作用。

Abstract: Peach fruits (Prunus persica var.Hakuho ) has been stored at low temperature (3℃).The effects of calcium on ripening of packaged fruits were studied in this paper. The results showed that:The treatment of calcium could inhibit the synthesis of ethylene. increasing of respiratory rate and activity of polygalacturoase while delny the climacteric peak and softness of fruits.It could inhibit also the cell membrane conductivity .So the treatment of calcium was useful to maintain the structure of cell wall and to delay the senescence of peach fruits.
