不同类型猕猴桃果实发育过程中内果皮色泽的动态变化
Dynamic Changes in Flesh Color in Different Kiwifruit Types during Fruit Development
摘要
Abstract
Different kiwifruit types such as ‘Kuimi ’ with green flesh ,‘Jinfeng ’ with yellow flesh and‘Hongyang ’ with red flesh were selected as materials .During the fruit development ,the chromism value of inner pericarp and the content of chlorophyll ,carotenoid ,anthocyanin in inner pericarp were detected to study the dy-namic changes in flesh color in different types of kiwifruit .The results showed that the flesh color of the three types of kiwifruit were green and their a*values were negative before 50 days after full bloom .The inner pericarp color of‘Hongyang’ kiwifruit became red and the a*value increased to 9.62±0.17.Chlorophyll and carotenoid can be detected in the three types of kiwifruit ,but only anthocyanin can be detected in ‘Hongyang ’ kiwifruit . The young kiwifruit had the highest content of chlorophyll with about 3.50 mg/(100g)FW.Then the content of chlorophyll in ‘Hongyang ’ kiwifruit declined constantly ,but followed by a gentle rise in ‘Kuimi ’ kiwifruit and fell down fast after a transient back up in ‘Jinfeng ’ kiwifruit .The content of carotenoid showed a little change during the fruit development progress .The content of anthocyanin in the inner pericarp of ‘Hongyang ’ kiwifruit continued to show an upward tendency and reached the maximum content of (1.46±0.06)mg/(100g)FW on the 130th day after full bloom.Therefore,the flesh color of ripen kiwifruit was the outcome of combined action of sev-eral kinds of pigment .‘Hongyang ’ kiwifruit appeared red due to the degradation of chlorophyll and the accumu -lation of anthocyanin .‘Jinfeng ’ kiwifruit appeared yellow ,which was caused by the decline of chlorophyll and the increase of the ratio of carotenoid content and chlorophyll content .The ratio of carotenoid content and chloro-phyll content held the line in ‘Kuimi’ kiwifruit.As a result,the‘Kuimi’ kiwifruit appeared green .The research results are helpful for the elucidation of color mechanism in kiwifruit in the future .关键词
