自然生草对库尔勒香梨果实采后贮藏品质的影响及贮藏预测模型的建立
Effect of natural grass on postharvest storage quality of Korla fragrant pear fruit and establishment of storage prediction model
摘要
Abstract
In order to explore the effects of natural grass and clean tillage on fruit quality of Korla fragrant pear during postharvest storage.In this study,the changes of internal and external quality of Korla fragrant pear during postharvest storage under two cultivation modes were compared and analyzed,and the time series model of internal and external quality of Korla fragrant pear during storage was established based on partial least squares method,so as to provide scientific basis for improving the storage quality of Korla fragrant pear.The results showed that during the postharvest storage of Korla fragrant pear,with the extension of storage time,the storage quality of Korla fragrant pear in natural grass area and clean tillage area decreased.The single fruit weight,fruit vertical and horizontal diameter,vitamin C,soluble sugar,peel chlorophyll a,peel carrot,pulp chlorophyll a and pulp carotenoid content of Korla fragrant pear in natural grass area changed significantly compared with those in clear tillage area.At the later stage of storage,the changes of carotene in peel and chlorophyll a in pulp of fruits in natural grass area were more significant than those in clean tillage area.At the end of storage,the soluble solids in the natural grass area changed significantly compared with the clear tillage area.The fruit shape index of natural grass area was higher than that of clear tillage area,but there was no significant difference.Comprehensive analysis showed that the quality of Korla fragrant pear in natural grass area and clean tillage area decreased during storage,but the storage quality of natural grass cultivated fragrant pear was higher than that of clean tillage.Based on the time series model established by partial least squares method,the determination coefficient(R2)of the validation set of each internal and external quality was greater than 0.7,the root mean square error(RMSC)was less than 0.8,and the residual prediction deviation(RPD)was greater than 2.It is proved that the time series model can accurately predict the change trend of internal and external quality of Korla fragrant pear during postharvest storage.关键词
