“…Given that roundness parameters tend to have values of 1 when objects are shaped as a perfect circle, the AR decreased from 1.66 to 1.61, and roundness slightly increased in ripe fruit. Similar reports of increased parenchymal cell size were observed in eggplants, showing an increase of between 60 and 100% in the cells of a baby eggplant and the cells of an commercially advanced mature eggplant (Valerga et al, 2019).…”

The cuajilote (Parmentiera edulis D.C.) tree produces fibrous fruits with a high content of lignocellulosic compounds. However, this fruit and their fibers have been scarcely studied. For this reason, an integral study of their cellular architecture, physicochemical, micromechanical, and structural properties in two maturity stages were carried out. Physicochemical tests, light, confocal and electron microscopy, microindentation, and X‐ray diffraction were used for the characterization of fruit and their fibers. Chemical analysis showed that the unripe fruits have the highest cellulose content (42.17%), but in ripe fruit the cellulose content decreases (32.76%) while lignin content increases from 35.26 to 40.79%, caused by the lignification of the sclerenchyma fibers. Microstructural and micromechanical studies in the different regions of the fruit provided relevant information about its cellular architecture, distribution of lignocellulosic compounds and its role in the micromechanical properties of their fibers. The thickening cell wall of sclerenchyma fibers was caused by the cellular lignification of the ripe fruits. According to the physicochemical and structural studies, cuajilote fibers are comparable to other fibers obtained from crops rich in lignocellulosic compounds. The current study provided new knowledge about the cellular architecture of fruit and criteria for selecting the ripening stage adequate for the extraction of cellulose or lignin. Furthermore, information regarding the micromechanical properties of their fibers and which structural arrangement could be more convenient for mechanical reinforcement of biodegradable materials was obtained.

“…A declining trend was detected along with development, as was found in previous studies. 23 Regarding the outcome of grafting, the DM content of grafted plants was, already at the baby stage, lower than in the control. Such differences were also observed at mid-CM and late-CM (Fig.…”

“…21 Given its subtropical origin, eggplant is very sensitive to chilling injuries, both in the field and during postharvest storage. [22][23][24][25] Interestingly, scion-rootstock compatibility studies 12,13,26 have shown that the species not only yields compatible intraspecific rootstocks but also interspecific combinations with tomato and several hybrids. 26,27 This markedly expands the rootstock-scion combinations to explore.…”

BACKGROUND Vegetable grafting has been increasingly evaluated to improve preharvest tolerance to biotic and abiotic stresses. However, very few studies have identified rootstock–scion combinations able to improve fruit shelf life and reduce the susceptibility to postharvest disorders. Herein, a purple eggplant scion (cv. Monarca) was grafted onto a cold‐tolerant hybrid Solanum rootstock (‘Java’) and the changes in growth, quality, postharvest chilling tolerance, and antioxidant stability were evaluated. RESULTS Eggplant grafting enhanced plant vigor and fruit growth rate, decreasing the time from set to harvest by 10–15%. Grafted eggplants had a thinner shape and lighter pulp color than the control. The rootstock–scion combination tested showed lower respiration (~60%), dry matter (~15–20%), and phenolic compounds contents (~15–20%) than eggplants from non‐grafted plants. Grafting markedly improved fruit performance during postharvest storage. Remarkably, grafted eggplants showed much higher tolerance to chilling injury than the control did, evidenced by a reduction of surface scalds along with decreased softening and pulp browning. The trend in antioxidants found at harvest time was reversed after cold storage due to enhanced stability (20% and 100% for pulp and peel respectively) in fruit from grafted plants. CONCLUSION Purple eggplant (cv. Monarca) grafting onto ‘Java’ hybrid rootstock modulated fruit growth, quality at harvest, and increased fruit chilling injury tolerance during storage. Grafting may be a bona fide strategy to induce phenotypic traits able to improve vegetable postharvest performance. © 2021 Society of Chemical Industry.
