摘　　要：为了研究库尔勒香梨成熟过程中理化指标间的相关性,探寻一种适合于评价库尔勒香梨采收成熟度的方法。该研究以整个成熟期的库尔勒香梨为研究对象,研究了在整个成熟期内库尔勒香梨硬度和可溶性固形物含量等理化指标的变化规律,并对指标的均值、变化速率和方差的变化规律进行了分析和试验验证。用Excel软件处理数据,结果表明:在整个成熟期内,香梨的硬度逐渐减小,可溶性固形物含量逐渐增加,二者呈明显的负相关,R2=0.991;二者的变化速率和方差均呈现先增大后减小的趋势,而峰值均在同一时间出现,且恰与香梨硬度减小曲线与可溶性固形物含量增加曲线的交点所对应的时间相同。据此提出了一种库尔勒香梨成熟度百分比评价方法,将库尔勒香梨的成熟度进行具体指标的量化,研究结果可为库尔勒香梨成熟度评价提供参考依据。In order to seek for a evaluation methodology which is fit for the Korla pear maturity,the research concentrated on the variation rules of the Korla pear＇s hardness and soluble solids content and physicochemical index in its mature period,analysed and verified its parameters of the mean value and mean change rate and the change rule of variance.With these softwares like excel and origin processing data,Korla pear＇s hardness and soluble solids content change rate and the variance between each control point all present the trend that the first increases,then decreases,but the peak value all appeared at the same time,it is the same time when pear hardness decrease curve and the soluble solids content increased curve cross.Accordingly we came up with a method based on physicochemical index to evaluate the Korla pear maturity percentage,then quantified the results.The results of the study can provide a reference basis for the Korla pear maturity evaluation.
