Effect of Different Concentrations Calcium Treatments on the Quality of Plum at Storage Period

Taking 'Suili No.3' as test material,the effect of different concentrations of calcium treatments on the quality of plum at storage period was studied,and the correlation between each index was analyzed.The results showed that 3% calcium treatment delayed respiratory peak,slowed down titratable acids content,soluble solids content and fruit hardness decreased rapidly,and reduced the rotten fruit rate.The results of correlation analysis showed that after storage,the rotten fruit rate showed significant negative correlation with fruit titratable acid content and fruit hardness and fruit soluble solid content were negatively related.
