Effects of calcium regulation and supplementation techniques on stone cell content and fruit quality in Korla fragrant pear
摘要
Abstract
[Objective]To explore the effects of endogenous calcium regulation and exogenous calcium supplementation techniques on stone cell content and fruit quality in Korla fragrant pear.[Methods]Eight-year-old Korla fragrant pear trees with an open-center canopy were used as experimental materials,and four different treatments were established:T1,foliar spraying of calcium regulator on April 12,April 23,May 12,July 24,and August 2;T2,same calcium regulator treatment as T1,with additional root flushing application of Calcium Quanwei on May 12 and August 2;T3,same calcium regulator treatment as T1,with additional root flushing application of imported calcium fertilizer on May 12 and August 2;CK,spraying with clear water.Stone cell content in fruits from each treatment and the diameter and density of stone cell clusters at the maturity stage were determined,and the effects of different treatments on external and internal quality of fruits at the harvest stage were analyzed.[Results]The stone cell content in Korla fragrant pear under T2 treatment was the lowest at all stages.Compared with CK,T1 treatment,and T3 treatment,the stone cell content under T2 treatment at the maturity stage was significantly reduced by 67.63%,43.25%,and 24.21%,respectively(P<0.05),and the diameter of stone cell clusters was reduced by 7.24%,4.37%,and 1.69%,respectively.At the harvest stage,the proportion of calyx shedding fruits under T2 treatment was the highest(66%).Compared with CK,T1 treatment,and T3 treatment,the single fruit weight of calyx shedding fruits under T2 treatment increased by 8.80%,3.37%,and 0.62%,respectively;fruit hardness increased by 19.36%,4.25%,and 0.78%,respectively;soluble solids content increased by 50.90%,14.57%,and 1.14%,respectively;vitamin C content increased by 46.49%,21.12%,and 3.89%,respectively;soluble sugar content increased by 13.29%,5.28%,and 1.83%,respectively;titratable acid content decreased by 27.27%,11.93%,and 4.95%,respectively;tannin content decreased by 43.06%,21.15%,and 12.77%,respectively;calcium content increased by 10.69%,4.46%,and 1.13%,respectively.[Conclusion]The synergistic regulation of calcium regulator and Calcium Quanwei can effectively reduce stone cell content in Korla fragrant pear fruits,increase the proportion of calyx shedding fruits,single fruit weight,and fruit hardness,elevate the contents of soluble solids,vitamin C,soluble sugars,and calcium in fruits,and decrease the contents of titratable acid and tannin,making it a suitable calcium regulation and supplementation technique for improving fruit quality in Korla fragrant pear.关键词
