Abstract

The colour, firmness and flavour of 101 peach fruit from the south side of the tree were related to the characteristics of fruit-bearing shoots using a multivariate approach. The variability of quality was high between fruit. Fruit from the upper parts of the tree were more purple, less orange-red, less firm, had a higher sucrose content, a lower citric acid content and a higher pH than fruit from the lower parts. Fruit well exposed during the day had a purple skin, whereas less exposed fruit were more orange-red and had higher luminance (L∗) and chrominance (a∗, b∗). Fruit exposed to light essentially in the afternoon were more purple, less yellow and orange and more firm, had a higher citric acid content, lower sucrose and malic acid contents than fruit exposed to light in the morning. Colour variables were weakly correlated to the total leaf area. Fruit borne by thick shoots with high total leaf area, high leaf area per fruit late in season and a high yield were sweet and had high malic acid content. Sour fruit were linked with high total leaf area and high leaf area per fruit early in season. A semantic model for quality elaboration is proposed.

Impact of factors contributing to internal disorders of mango (Mangifera indica L.) fruit—A systematic literature review
2024, Scientia Horticulturae
The expression of internal disorders is a complex phenomenon due to the interaction of genotype, environment, and management practices at the pre-harvest, harvest, and post-harvest stages. This study aims to provide a comprehensive overview of factors associated with, and have been investigated in relation to, the susceptibility and expression of internal disorders in mango. In this context, a systematic literature review was conducted to identify, extract, and analyse the most pertinent data. Six hundred and fifty-seven studies were sourced from three databases. Of these, 72 were relevant after screening based on exclusion-inclusion criteria. An additional nine relevant studies were identified through manual searches and included in the final data synthesis. From the 81 studies, the prevalent disorders were spongy tissue and jelly seed, followed by flesh browning and soft nose. ‘Alphonso’ expressed only spongy tissue disorder. By contrast, ‘Tommy Atkins’ simultaneously expressed multiple disorders, viz., soft nose, jelly seed, and stem-end cavity. Mineral composition of flesh and exposure to heat post-harvest (viz., sunlight, phytosanitary heat treatment, and elevated storage temperature) were prominent in association with IDs expression. Relatively high N, N/Ca, Mg/Ca, and K/Ca ratios and relatively low Ca and B were related to most disorders. With K and Mg, studies inconsistently suggested positive and inverse relationship with a particular disorder. While individual studies suggest casual relationships, there was a relative dearth of pre-harvest work on soil characteristics, growing conditions (e.g., temperature, rain, and VPD), crop physiology (e.g., age and biennial bearing) and management practices (e.g., fertilisation and irrigation) in the literature. This review provides a benchmark against which future research might adopt holistic approaches to contiguously ascertain predisposition of mango fruit to internal disorders across the pre-harvest, harvest, and post-harvest continuum.
Rootstock vigor dictates the canopy light environment that regulates metabolite profile and internal fruit quality development in peach
2024, Plant Physiology and Biochemistry
Five rootstock cultivars of differing vigor: vigorous (‘Atlas™’ and ‘Bright's Hybrid® 5’), standard (‘Krymsk® 86’ and ‘Lovell’) and dwarfing (‘Krymsk® 1’) grafted with ‘Redhaven’ as the scion were studied for their impact on productivity, mid-canopy photosynthetic active radiation transmission (i.e., light availability) and internal fruit quality. Αverage yield (kg per tree) and fruit count increased significantly with increasing vigor (trunk cross sectional area, TCSA). Α detailed peach fruit quality analysis on fruit of equal maturity (based on the index of absorbance difference, I_AD) coming from trees with equal crop load (no. of fruit cm⁻² of TCSA) characterized the direct impact of rootstock vigor on peach internal quality [dry matter content (DMC) and soluble solids concentration (SSC)]. DMC and SSC increased significantly with decreasing vigor and increasing light availability, potentially due to reduced intra-tree shading and better light distribution within the canopy. Physiologically characterized peach fruit mesocarp was further analyzed by non-targeted metabolite profiling using gas chromatography mass spectrometry (GC-MS). Metabolite distribution was associated with rootstock vigor class, mid-canopy light availability and fruit quality characteristics. Fructose, glucose, sorbose, neochlorogenic and quinic acids, catechin and sorbitol were associated with high light environments and enhanced quality traits, while sucrose, butanoic and malic acids related to low light conditions and inferior fruit quality. These outcomes show that while rootstock genotype and vigor are influencing peach tree productivity and yield, their effect on manipulating the light environment within the canopy also plays a significant role in fruit quality development.
Plant architecture manipulation increases cannabinoid standardization in ‘drug-type’ medical cannabis
2021, Industrial Crops and Products
Citation Excerpt :
In larger plants the microclimate, hormonal, physiological and developmental differences would be bigger and may increase variation across the plant. For example, in lavender, variation between locations along the plants in essential oil contents and composition were observed between plants harvested after reaching different heights (Dudai et al., 1999), and at least 11 variables that are affected by plant size were detected to effect peach quality (Génard and Bruchou, 1992). The results of the present study validate the potential of plant architectural modulation for regulation of the secondary metabolite profile in medical cannabis.
A major challenge in utilizing cannabis (Cannabis sativa L.) for modern medicine is the lack of standardization throughout the plant of cannabinoids, the unique therapeutic secondary metabolites in cannabis. The present study focused on the interplay between plant architecture modulation and standardization of the secondary metabolite profile in medical cannabis plants. Secondary metabolism is considerably affected by endogenous and exogenous factors, including positional-developmental aspects and microclimate. We hypothesized that manipulation of the plant architecture, which alter morphological and reproductive development, as well as micro-climate in the shoot will impact secondary metabolism and spatial standardization of the cannabinoids. Eight plant architecture-modulation treatments were evaluated for effects on in-planta concentrations and standardization of the cannabinoids, and on the morpho-physiological state of the plants. Two medical-cannabis genotypes of 'drug-type' medical cannabis were analyzed to evaluate genotypic sensitivity. The results reveal that plant architecture modulation can increase standardization of the cannabinoid profile in cannabis, thereby supporting the hypothesis. The architectural modulating treatments increased uniformity of cannabinoid concentrations in the plant by increasing concentrations at the lower parts of the plant. The cannabinoid profile was most affected by treatments that had the largest impact on plant structure such as the removal of primary and secondary branches. Decarboxylation of the cannabinoids in-planta was not affected by structural modulation. The spatial uniformity of cannabinoid concentrations throughout the cannabis plant is cannabinoid and genotype specific, and the effect of architecture modulation on cannabinoid standardization is genotype specific.
Environmental and orchard bases of peach fruit quality
2018, Scientia Horticulturae
This article provides an overview of preharvest factors that affect peach fruit quality attributes. Improvement of peach fruit quality is impossible postharvest. Hence, optimum peach quality at harvest and during postharvest and subsequently, consumer satisfaction, is achievable through understanding the influence of preharvest environmental and orchard factors. ‘Quality’ definition for producers, packers, shippers and consumers is discussed, with a description of the most important peach quality attributes and the physiological mechanisms that affect them. The effect of cultivar, rootstock, harvest time, crop load management, light manipulation, fruit position in the canopy, irrigation, fertilization and the impact of the growing environment on peach and nectarine harvest quality are reviewed. The development of new technologies that help clarify the biological and horticultural bases of preharvest factors on peach fruit quality can help increase peach consumption.
Modeling sugar content of pineapple under agro-climatic conditions on Reunion Island
2016, European Journal of Agronomy
A process-based model simulating the change in total soluble solids (TSS (%)) in fruit flesh was developed to describe the effect of climatic conditions on the sugar content of ‘Queen Victoria’ pineapple at harvest on Reunion Island. Sugar content varies throughout fruit development according to three processes (the supply of carbohydrates to the fruit, fruit metabolism, and dilution) which are affected by environmental factors, mainly temperature, rainfall and fertilization. The ecophysiological model of soluble sugar accumulation was linked to SIMPIÑA, a crop model that accurately predicts the daily increases in flesh dry and fresh weight. When the process-based model and crop model were linked, the dry and fresh matter of the pineapple flesh, as affected by climatic conditions, could be used as inputs to predict the TSS (%) at harvest. The relative rate of transformation of carbon as sugars in the fruit flesh for the synthesis of compounds other than sugars was estimated during fruit growth. TSS (%) were compared for harvested fruit grown under eight agro-climatic conditions. In the flesh of fruit harvested close to maturity, i.e., at 1400 degree-days after flowering, TSS (%) were significantly related (r² = 0.55, P < 0.001) to total soluble sugar content. The variability of TSS (%) between the eight agro-climatic groups ranged from 16.9 for pineapples grown in dry locations irrigated, under N-deficit conditions to 19.4 for pineapples grown in dry locations, without irrigation and without N deficiency. The variability of TSS (%) was substantial within each of the eight agro-climatic groups: standard deviations ranged from 0.9 to 1.5 for pineapples grown in dry locations, irrigated, without N deficiency and in dry locations, without irrigation and without N deficiency, respectively. For data from 14 experiments conducted under different climatic conditions, N fertilization, and irrigation conditions, the model predicted the TSS (%) at harvest with an RRMSE of 0.04. By linking this sugar model to the SIMPIÑA crop model, the impact of environmental conditions and cultural practices on the growth and development of pineapple are taken into account to predict the gustatory quality of pineapple grown on Reunion Island. The model could have a practical application to manage fruit quality, plan harvest, and marketing.
Performance profiling of Prunus persica (L.) Batsch collection and comprehensive association among fruit quality, agronomic and phenological traits
2016, Scientia Horticulturae
Nowadays, although there are several studies based on peach phenotypic diversity and adaptability, there is no current research regarding associations among characters using multivariate statistical methods which provide more trustable conclusions than bivariate analysis. For this reason, we evaluated not only the adaptability of the accessions but also the relationships among qualitative and quantitative traits applying Multiple Correspondence Analysis and Factor Analysis, respectively. The study was carried out on seventy-seven nectarine and one hundred and thirty-two peach accessions grown in Argentina that were characterized with 35 fruit quality, agronomic and phenological traits during 3 seasons. Multiple Correspondence Analysis revealed that freestone trait would be associated with strong anthocyanin coloration of the flesh around the brown dark stone while semi-freestone trait would be related to weak or no anthocyanin coloration of the flesh around the light brown stone. Then, Factor Analysis enabled us to identify positive relationships between blooming and sprouting date; harvesting period and yield and among fruit development period, harvesting date, fruit weight and soluble solid content. In addition, ‘phenology traits’, ‘productivity’ and ‘fruit quality and reaping time’ would be unrelated to each other. Furthermore, the agglomerative hierarchical cluster analysis grouped the accessions in accordance to their similarities and allowed the identification of the most adapted cultivars. We have demonstrated that this approach is a powerful tool that should be considered for further studies on peach germplasm and it has also the possibility to be applied for other fruit species. Finally, the results of this study provide valuable information for germplasm characterization and for breeding practices aiming to develop accessions adapted to the climatic conditions of the northern of Buenos Aires province.
