Abstract

We present a detailed study of differences in the fruit ripening stage on the vines and ethylene treatment in the red kiwifruit cultivar ‘Rainbow Red’ ( Actinidia chinensis ). We evaluated the fruit quality (core and flesh firmness, soluble solid content (SSC), and titratable acid (TA)); ethylene metabolism; and gene expression of ACS1 , ACO3 , EIL4 , ERF14 , and PGB at each stage. Fruits on the vines somewhat softened gradually. SSC increased, and core and flesh firmness as well as TA decreased gradually. However, rapid ethylene production was not observed, and gene expression of ACS1 , ACO3 , EIL4 , ERF14 , and PGB was at the basal level at each stage. While the fruit quality following ethylene conditioning, core and flesh firmness, and TA rapidly decreased, SSC and ethylene production rapidly increased. It was confirmed that gene expression of ACS1 , ACO3 , EIL4 , ERF14 , and PGB rapidly increased. These results suggested that the ripening of ‘Rainbow Red’ on the vines is not associated with ethylene.
红猕猴桃品种“彩虹红”的果实成熟过程
本文对彩虹红猕猴桃品种(Actinidia chinensis)果实成熟期和乙烯处理的差异进行了详细的研究。我们评估了果实品质(果核和果肉硬度、可溶性固形物含量(SSC)和可滴定酸(TA));乙烯代谢;各组ACS1、ACO3、EIL4、ERF14、PGB的基因表达。葡萄藤上的果实渐渐变软了。SSC增加,核心和果肉紧实度以及TA逐渐降低。但未观察到快速的乙烯生成,ACS1、ACO3、EIL4、ERF14和PGB基因在各阶段的表达均处于基础水平。乙烯处理后的果实品质、果核和果肉紧实度以及TA迅速下降,而SSC和乙烯产量迅速增加。证实ACS1、ACO3、EIL4、ERF14、PGB基因表达迅速升高。这些结果表明,“彩虹红”在葡萄藤上的成熟与乙烯无关。
