Changes of mineral elements of some Kiwifruit cultivars during cold storage

The changes of mineral elements of the Abbot, Alison, Bruno, Monty and Hayward cultivars of kiwifruit (Actinidia deliciosa CV) were obtained from The Iran Research Center of Citrus (Tonekabon, North part of Iran) and were measured by ICP (Inductively Coupled Plasma) in the cold storage (at T= 0-4 0C, RH=75-85%) during 0, 9 and 18 weeks. Content of mineral elements (after harvesting) were in the ranges: Ca (42.726- 79.590), K (279.890-372.271), Mg (18.977-32.799), Na (1.444-2.5), Fe (0.290-0.521), P (31.296-42.221), Cu (0.037-0.207), Zn (0.162-0.308) and Mn (0.042-0.062 mg/100g fw). Statistical analysis showed that, potassium was the main mineral elements in the all studied cultivars and the Alison cultivar had the highest contents of mineral elements. In all cultivars of kiwi fruit the contents of mineral elements was significantly change during cold storage (P<0.01).
