Summary
This study was conducted in Seed and Plant Improvement Institute, Karaj, Iran for six months during 2011 to survey of store types effects on bulb losses rates and some bulb quality traits in six Iranian onion genotypes. First factor or store types (A) with two levels composed common store (temp 4-15co\n and p-75 R.H.) and cold store (temp 7 co and 70-75 R.H.) and second factor (B factor) was six onion genotypes composed Azarshahr Red, Neyshaboor White, Gholyghese1, Gholyghese2, Gholyghese3 and Gholyghese4. Experimental design was factorial base on CRD with three Replications. Each plot and 5\n kg uniform bulbs were placed in plastic net. Start time of experiment was 19th October for 4 months. Quantitative traits such as bulb weigh loss percentage and bulb sprouting percentage, bulb qualitative traits such as dry matter percentage, TSS, tissue firmness and pyrovic acid content were recorded in final of experiment. Results showed that cold store reduced losses rates in comparison with common store. Neyshaboor White, Gholyghese2 and Gholyghese4 genotypes were the best genotypes with losses minimum. Pyrovic acid content was the highest in cold store especially in Gholyghese1 and Gholyghese2 genotypes. Dry matter percentage also was higher in cold store than common store. The results this study indicated a preference of cold store condition is in reduce the storage quantity waste and some quantitative factors such as bulb firmness. The storage quantity waste in Gholyghese3 genotype was the lowest. Results of the current study revealed that Gholyghese3 genotype at cold store condition had better treatment.
