“…In contrast, the skin of early immature fruit had two layers of dense and rounded epidermis, which were expected to be more resistant to cracking. Tensile strength studies confirmed this trend: the skin of mature fruit had a lower elastic modulus than that of young fruit [ 8 ].…”

“…An anatomical study showed that the skin of ripening pomegranate fruit is made up of epidermal cells that are relatively flat and spaced apart; these were expected to be less durable under internal pressure [ 8 ]. In contrast, the skin of early immature fruit had two layers of dense and rounded epidermis, which were expected to be more resistant to cracking.…”

“…Strengthening Pomegranate Skin against Cracking: Cutin, Suberin, Wax, and Cell Wall Pomegranate peel is prone to cracking, which is probably induced by differences in growth rate between the fruit peel and flesh, and the pressure imposed by the quickly expanding arils on the stretched peel [10]. Extreme and changing temperatures may further affect incoming and outgoing water fluxes, adding more strain on the peel [8]. In addition, the anatomy of the skin and peel characteristics may affect skin susceptibility to cracking and fruit splitting.…”

“…The fruit skin has a dual role; it protects the fruit from environmental stresses and at the same time plays a critical role in resisting internal growth pressures, controlling fruit expansion, and maintaining fruit integrity. The pomegranate skin is comprised of epidermis cells covered by a cuticle [ 8 ]. Symptoms of cracking and russeting in pomegranate develop first as tiny cracks in the cuticle, and cv.…”

“…It has been suggested that cracking is induced by differences in growth rate between the fruit peel and flesh, and the pressure imposed by the quickly expanding arils on the stretched peel [10]. Extreme and changing temperatures may further affect incoming and outgoing water fluxes, adding more strain on the peel [8]. Finding the factors that strengthen the skin against cracking is of significant economic importance.…”

The appearance of pomegranate (Punica granatum L.) fruit is highly important for its marketing. The primary concerns are obtaining sufficient red pigment accumulation and minimal cracking of the fruit skin (the outer red layer of the peel). We analyzed the skin transcriptome of pomegranate cv. Wonderful at distinct time points of fruit development to characterize the processes that occur in the skin during fruit ripening and which may reflect on processes in the whole fruit, such as the non-climacteric nature of pomegranate. The data suggested a ripening mechanism in pomegranate skin that differs from that in strawberry—the model plant for non-climacteric fruit where abscisic acid is the growth regulator that drives ripening—involving ethylene, polyamine, and jasmonic acid pathways. The biosynthetic pathways of important metabolites in pomegranate—hydrolyzable tannins and anthocyanins—were co-upregulated at the ripening stage, in line with the visual enhancement of red coloration. Interestingly, cuticle- and cell-wall-related genes that showed differential expression between the developmental stages were mainly upregulated in the skin of early fruit, with lower expression at mid-growth and ripening stages. Nevertheless, lignification may be involved in skin hardening in the mature fruit.

One of the major issues with pomegranate production in arid and semi-arid climate is the white arils of fruit. The known plant regulators abscisic and jasmonic acids play a variety of roles in plant growth and the reduction of abiotic stresses. However, little is known about their application to improve the quality of pomegranate fruit, particularly white arils, in semi-arid environments. Herein, the experiments, in this study, were performed in two consecutive seasons 2020 and 2021 on 10-year-old Wonderful pomegranate trees to spotlight the improvement of the aril coloration and fruit quality by spraying with abscisic and jasmonic acids under semi-arid climatic conditions. Fifteen Wonderful pomegranate trees were subjected to five treatments (three replications for each). The tested treatments included abscisic acid (ABA) at the concentrations of 600 and 800 µg−1 mL, jasmonic acid (JA) at the concentrations of 10 and 15 Mm, and the control treatment (distilled water). The physical and chemical characteristics of the fruit quality of Wonderful pomegranate improved significantly when the trees were treated with abscisic or jasmonic acids. The foliar addition of ABA at 600 and 800 µg−1 mL increased the anthocyanin index by 96.74 and 114.75%, respectively, in the first year and by 49.48 and 67.62% in the second year, in comparison with the control. The foliar addition of ABA at 800 µg−1 mL was more effective than jasmonic acid in enhancing most of the chemical fruit properties, especially the anthocyanin index. The high level of ABA (800 µg−1 mL) gave the minimum fruit acidity and the highest fruit quality. Abscisic acid induces the fruit acidity and enhances the aril coloration in Wonderful pomegranate. In semi-arid conditions, it is recommended to spray the Wonderful pomegranate trees with abscisic acid at 800 µg−1 mL to improve the fruit quality and to increase the aril coloration.
