Advanced in Rootstock Breeding of Nut Trees: Objectives and Strategies

Kourosh Vahdati Saadat Sarikhani Mohammad Mehdi Arab Charles A. Leslie Abhaya M. Dandekar

The production and consumption of nuts are increasing in the world due to strong economic returns and the nutritional value of their products. With the increasing role and importance given to nuts (i.e., walnuts, hazelnut, pistachio, pecan, almond) in a balanced and healthy diet and in the prevention of various diseases, breeding of the nuts species has also been stepped up. Most recent fruit breeding programs have focused on scion genetic improvement. However, the use of locally adapted grafted rootstocks also enhanced the productivity and quality of tree fruit crops. Grafting is an ancient horticultural practice use in nut crops to manipulate scion phenotype and productivity and overcome biotic and abiotic stresses. There are complex rootstock breeding objectives and physiological and molecular aspects of rootstock–scion interactions in nut crops. In this review, we provide an overview of these, considering the mechanisms involved in nutrient and water uptake, regulation of phytohormones, and rootstock influences on the scion molecular processes, including long-distance gene silencing and trans-grafting. Understanding the mechanisms resulting from rootstock × scion × environmental interactions will contribute to developing new rootstocks with resilience in the face of climate change, but also of the multitude of diseases and pests and of the possible increase of their aggressiveness. They will also have to offer the premises of economic production, respectively yield and the quality, according to multiple destinations of nuts in the current consumption and food industry, but also the increasing exigencies of the consumer market and the profile industry.

Insights into chestnut (Castanea spp.) graft incompatibility through the monitoring of chemical and physiological parameters

Planta (2025)

Giovanni Gamba Dario Donno Burak Akyüz Beatriz Cuenca Valera Gabriele Loris Beccaro

Abstract Main conclusion Incompatible chestnut grafts exhibited a notably reduced stomatal conductance, mirroring the trend observed for leaf chlorophyll content. Woody tissues at the graft interface of these combinations showed a significantly higher total phenolic content, especially in the internal layers. Abstract In recent years, significant efforts have been made to study the mechanisms of graft incompatibility in horticultural species, though research on minor species like chestnut remains limited. This study investigated the physiological and chemical dynamics in various chestnut grafts, aiming to develop a method for the early detection of graft incompatibility. The total phenolic content (TPC) and specific phenolic markers were analyzed at two phenological stages, callusing (CAL) and end of the vegetative cycle (EVC), using spectrophotometric and chromatographic techniques. These analyses were performed on three sections comprising the graft. Stomatal conductance (G sw ) and leaf chlorophyll content were assessed during the growing season as support tools, being non-destructive useful indicators of plant water status. Significant differences in the physiological traits among compatible and incompatible grafting combinations were evident and remained stable throughout the season. Compatible combinations consistently displayed greater leaf chlorophyll content and higher stomatal conductance, highlighting their superior physiological performance. TPC increased significantly from the CAL to EVC stage across all experimental grafting combinations and in all three analyzed sections. Greater phenol accumulation was observed at the graft union of incompatible combinations, particularly in the inner woody tissues. The phytochemical fingerprint revealed castalagin as the dominant compound, with significant increases in benzoic acids, catechins, and tannins during the growing season. However, the role of gallic acid and catechin as markers of graft incompatibility remains uncertain. The multidisciplinary approach provided valuable insights into the issue of graft incompatibility.

SOIL USE EFFICIENCY AND ECOLOGICAL FOOTPRINT OF PEACH AND NECTARINE PRODUCTS

Acta Horticulturae (2015)

Gabriele Loris Beccaro Alessandro Kim Cerutti Dario Donno Giancarlo Bounous Simone Contu

In recent years the attention to the soil as a limited resource that has to be preserved is increased. Therefore both a careful soil management and the adoption of practices that lead to a significant reduction of soil occupation are becoming ever more necessary. Considering orchard systems, it is important to increase the efficiency in the use of such resource; nevertheless the consumption of the soil has to be considered in a broader perspective. In this study, an assessment of the consumption of the three types of soil use (direct, indirect and virtual) was performed under different growing practices for peach and nectarine orchards. The considered orchard management protocols were: conventional, integrated and organic, in five commercial orchards for each protocol. Results clearly show that the higher yield of production in the conventional practice leads to a reduction of the direct soil use (therefore an apparent soil use efficiency), nevertheless it leads also to a significant increase of the indirect and virtual soil use.

Castanea spp. Nut Traceability: A Multivariate Strategy Based on Phytochemical Data

Applied Sciences (2023)

Elisabetta Prezzi Dario Donno Maria Gabriella Mellano Gabriele Loris Beccaro Giovanni Gamba

The phytochemical characterization of Castanea spp. fruits is very important for the development of effective strategies for the biodiversity conservation and traceability of chestnuts, as the chestnut is one of the most important Italian and European nut and forest species. In this study, several cultivars of C. sativa (sweet chestnuts and “marrone-type”), C. crenata, and hybrids of C. sativa × C. crenata were characterized by spectrophotometric (Folin–Ciocalteu assay for the total polyphenolic content and ferric reducing antioxidant power test for the antioxidant capacity) and chromatographic (high-performance liquid chromatography coupled to a diode array UV-Vis detector) protocols to define their phytochemical composition and nutraceutical properties. The phytochemical results were then used to build a multivariate statistical model (by principal component analysis) and obtain an effective and rapid tool to discriminate unknown cultivars (i.e., no information about their origin) belonging to different species. The multivariate approach showed that the genotype was a significantly discriminating variable (p < 0.05) for the phytochemical composition. Polyphenols (in particular, phenolic acids and tannins) have been identified as the main bioactive classes with the highest discriminating power among the different genotypes. The total polyphenol content (TPC) and antioxidant capacity (AOC) showed a rich presence of bioactive compounds (74.09 ± 15.10 mgGAE 100 g−1 DW and 11.05 ± 1.35 mmol Fe2+ kg−1 DW, respectively), underlining the potential health benefits and functional traits of chestnuts. The principal component analysis applied to phytochemical variables has proved to be an excellent and effective tool for genotype differentiation to be used as a preliminary method for identifying the species of Castanea spp. fruits with an unknown origin. The present study showed that a multivariate approach, based on phytochemical data and preliminary to genetic analysis, may represent a rapid, effective, and low-cost tool for the traceability and quality evaluation of chestnuts from different species and hybrids with no information on their origin.

Castanea species show high levels of diversity (morphological and ecological traits, vegetative and reproductive habits, wood characteristics, adaptability and resistance to biotic and abiotic stresses, etc.), reflecting the adaptation of the genus to different environmental conditions. Tree shape and form are variable. C. dentata and C. sativa are upright, tall, and slender trees, whilst other species are smaller, with round foliage and branches that start from the base. Other species are dwarf shrubs. Plants can live and be regularly productive for centuries. Some species grow rapidly and re-sprout quickly when cut. Nut size, peeling, and pulp characteristics vary greatly among species and cultivars, and represent important features in the food market. Chestnut is a good source of nutrients, and it has a steady consumption in the main producing countries. Due to its mineral elements and bioactive compounds, chestnut can be considered a health-promoting food.
