A Study on the Variation in Physical and Chemical Indicators of Korla Fragrant Pear in the Mature Period
摘要
Abstract
This research aims to study the variation in physical and chemical indicators of Korla fragrant pear in the ma -ture period and explore the correlation among the main indicators .Taking the Korla fragrant pear in the mature period as the objects , the changes of the fruit firmness , chlorophyll content , SSC and the content of Vitamin C were studied .Using the methods of correlational analysis and regression analysis , the correlation between the means and the above indicators was analyzed by the support of SPSS and excel .The results were verified by experiments .Research results show that the ranges of physical and chemical indicators of Korla fragrant pear in the mature period are 4 .23~7 .99 kg/cm2 firmness , 3.17~6.54mg/100g chlorophyll, 11.54~11.41%SSC, 0.36~0.6mg/100g Vitamin C, respectively.With the fruit maturity , the fruit firmness and chlorophyll content decrease gradually , while SSC and the content of Vitamin C increase gradually.The means of each indicator have significant correlation at the level of 0.01.In the process of regression anal-ysis, the optimal fitting was selected and the corresponding mathematical model was established .Both the determination coefficients of fruit firmness and SSC as well as the content of chlorophyll and Vitamin C were greater than 0 .95 .The er-ror of the predicted value and the measured data was less than 3 .21% through verification .Therefore , the content of chlorophyll and Vitamin C can be predicted from the fruit firmness and SSC during the maturity of Korla fragrant pear . The research results can provide reference for evaluation and classification of Korla fragrant pear maturity .关键词
