钙处理对白菜生长发育及货架寿命的影响

以白菜为试材,研究了不同浓度氯化钙对其生长特性及货架寿命的影响。结果表明:(1)低浓度钙处理能促进白菜的生长发育,提高其产量,其中以0.25?Cl2处理效果最好;(2)钙处理可明显降低白菜腐烂率,增加组织中钙的含量,抑制白菜的膜脂过氧化作用,降低质膜透性和呼吸强度,延长白菜的货架寿命。其中以1.0?Cl2处理延缓组织衰老腐烂效果最好。

Influences of Calcium Treatment on the Growth Characters and Shelf Lives of Chinese Cabbage

The influences of Calcium treatment on the growth character and shelf life of Chinese cabbage were studied in this paper .The results indicated: (1) The calcium treatment of low density could promote the growth of Chinese cabbage, and improved its output. The treatment of 0.25?Cl2 had the best effect. (2) The calcium treatment could obviously lower the rot rate of Chinese cabbage and improve the calcium content of tissue .The membrane lipid peroxidation was inhibited and the membrane permeability, respiration intensity was reduced when Chinese cabbage was treated with calcium .The shelf life of Chinese cabbage could be prolonged .The treatment of 1.0?Cl2 had the best effect on delaying the senescence and rot of the tissue.
