Abstract

Rootstocks influence several fruit qualitative parameters. The aim of the study was to investigate the role of the rootstock on the accumulation of primary and secondary metabolites in the juices of sweet blood orange cv. Tarocco Sciré at different maturation stages. The tested rootstocks were Carrizo citrange, widely spead in the citrus industry, in comparison with C35 citrange, Bitters and Furr citrandarins recently introduced and on which little informations are available. Three simple sugars and 28 different specialized metabolites were quantified by HPLC/Uv-vis/DAD and HPLC/ESI-MS, the antioxidant potential was assessed by ABTS⁺ and DPPH^•. Analytical data obtained were processed by robust statistical tools that allowed us to highlight the role of the metabolites during maturation for the nutraceutical value. Bitters and C35 anticipated fruit ripening of nearly one month; Bitters and Furr reached the highest pigmentation one month earlier than the other genotypes.

砧木对血橙代谢物含量及抗氧化潜能的影响

砧木影响果实的几个质量参数。本研究旨在探讨砧木对甜血橙汁液中初级和次级代谢物积累的作用。不同成熟阶段的芋头。试验的砧木是在柑橘产业中广泛使用的Carrizo柑橘，与最近引进的C35柑橘、Bitters和Furr柑橘相比，这些砧木的资料很少。采用HPLC/Uv-vis/DAD和HPLC/ESI-MS测定3种单糖和28种不同的特化代谢物，采用ABTS+和DPPH•.测定抗氧化能力；获得的分析数据通过强大的统计工具进行处理，使我们能够突出代谢物在成熟过程中的作用，以获得营养价值。苦味和C35预期果实成熟近一个月；Bitters和Furr比其他基因型早1个月达到最高色素沉着。
