“…Genetic expression of ParPAL1 was the highest in ‘Goldrich’. This accession has been previously identified as a contributor of phenolic compounds content in its derived hybrids [ 8 ]. Indeed, phenylalanine ammonia-lyase (PAL) plays a significant role in the phenylpropanoid metabolism pathway.…”

“…For testing the contribution of ‘Goldrich’ to the phenolic content and genetic expression in the set of accessions, we performed a regression of the data to a general linear model [ 8 ]. In the model, the phenotype is linearly explained as follows: Phenotype = C + G Goldrich + Year + G Goldrich × Year + Residual.…”

“…These secondary metabolites remain in different plant organs and accumulate on the plant surface [ 5 ]. In the case of flavonoid compounds, their accumulation is unequally distributed within tissues, as its concentration is higher in the peel of several fruits such as apple [ 6 ], peach [ 7 ], or apricot [ 8 ].…”

“…Nevertheless, although the main steps of the metabolic pathway are described, the identification of key gene enzymes and their roles in the phenylpropanoid pathway of some fruit crops remain uncertain. As the first step for a better understanding of the phenolic pathway in fruits, we selected a set of apricot accessions from the IVIA’s apricot breeding program with genetic-based differences in phenolic compound accumulation [ 8 ].…”

There is an increasing interest in polyphenols, plant secondary metabolites, in terms of fruit quality and diet, mainly due to their antioxidant effect. However, the identification of key gene enzymes and their roles in the phenylpropanoid pathway in temperate fruits species remains uncertain. Apricot (Prunus armeniaca) is a Mediterranean fruit with high diversity and fruit quality properties, being an excellent source of polyphenol compounds. For a better understanding of the phenolic pathway in these fruits, we selected a set of accessions with genetic-based differences in phenolic compounds accumulation. HPLC analysis of the main phenolic compounds and transcriptional analysis of the genes involved in key steps of the polyphenol network were carried out. Phenylalanine ammonia-lyase (PAL), dihydroflavonol-4-reductase (DFR) and flavonol synthase (FLS) were the key enzymes selected. Orthologous of the genes involved in transcription of these enzymes were identified in apricot: ParPAL1, ParPAL2, ParDFR, ParFLS1 and ParFLS2. Transcriptional data of the genes involved in those critical points and their relationships with the polyphenol compounds were analyzed. Higher expression of ParDFR and ParPAL2 has been associated with red-blushed accessions. Differences in expression between paralogues could be related to the presence of a BOXCOREDCPAL cis-acting element related to the genes involved in anthocyanin synthesis ParFLS2, ParDFR and ParPAL2.

“…The use of nets could also be disadvantageous, due to a higher initial cost of the plantation and, above all, the possibility of negatively affecting the floral differentiation and the development, quality and color of the fruit. In this context, although some researchers have studied apricot quality, antioxidants, and polyphenols compounds [6,12,13], to our knowledge, there are no reports that have focused on the influence of protective net cultivation on these apricot fruit compounds.…”

Response of Apricot Fruit Quality to Protective Netting

The cultivation of fruit trees in protected environments is a technique that has been developed in recent years for peaches and nectarines, but not for apricots. This study was conducted to investigate the chemical composition of the fruits and their quality indices variations of the variety ‘Mikado’ as a function of its cultivation under a protective net or outdoors. As a practical agronomic assay, a homogeneous experimental plot was used in this study, where half of the apricot trees were cultivated under protective netting, and the other half without it. The data showed that for the total yield, no statistically significant differences were found with respect to ‘Mikado’ trees cultivated with or without a net. The trees cultivated under protective nets showed higher fruit weights. The results showed that the technique of using protective nets for the cultivation of extra-early apricot ‘Mikado’ is a profitable alternative for farmers, and their use does not affect fruit production or quality.
