Effect of irrigation time and amount on cracking rate and quality of apricot plum fruit
In order to investigate the effect of irrigation time and irrigation amount on cracking rate and quality of a-pricot plum(Prunus domestica×armeniaca)fruit,a two-factor test was conducted.The irrigation time was set at the veraison stage,initial mature stage and mature stage,respectively,and the irrigation amount was set as 80 m3 and 120 m3 per plot,respectively.The cracking rate and quality indexes of fruit,including fruit hardness and contents of soluble solids,vitamin C,soluble sugar,titratable acid,calcium,potassium,cellulose,pectin,free proline,were analyzed after fruit ripening.It was shown that the lowest fruit cracking rate was achieved by irrigating 80 m3 at the veraison stage.The cracking rate of fruit was significantly(P<0.05)negatively correlated with the calcium content in peel and pulp of fruit,which was revealed by the correlation analysis.Given the determined quality indexes of fruit,the best comprehensive quality of apricot plum fruit was found under the treatment of irrigating 80 m3 at the ve-raison stage,which was calculated by the principal component analysis.
