Morphological description in wild grape fruits [Ampelocissus acapulcensis (Kunt) Planch]

Resumen

seeds of the wild grape, Ampelocissus acapulcensis (Kunt) Planch, collected in the Costa Chica region of Guerrero, México. Design/Methodology/Approach: Fruits were collected, processed, and analyzed in the laboratory of the Universidad Autónoma de Guerrero. Evaluated variables included number of fruits per bunch, bunch weight, fruit weight, polar and equatorial diameters, shape index, fruit color, number of seeds per fruit, and seed traits (weight, diameter, and shape). Each morphological character was also documented photographically using a digital camera. Data analysis was conducted using SAS software, with central tendency statistics calculated for all measured traits. Results: Individual fruits averaged 5.05 g in weight, with mean polar and equatorial diameters of 19.08 mm and 19.57 mm, respectively. Fruit shapes ranged from globose to round or elliptic. The epicarp exhibited a purple‑red hue, while the pulp was translucent and viscous. Dry seeds weighed approximately 0.15 g, were heart-shaped and black in coloration, and each fruit contained between 1 and 4 seeds. On average, the fruit biomass was distributed as 12.93% epicarp, 74.35% mesocarp, and 12.72% endocarp. Limitations and Implications: Although several vine species, including wild grape, occur in the tropical deciduous forest of the region, their fruits remain poorly studied. This lack of information limits potential applications for health, nutrition, and economic development. Findings/Conclusions: The fruits of A. acapulcensis exhibit promising morphological quality, yet further research is required to fully explore their potential.
