Eco-physiological attributes of Physalis philadelphica, Physalis angulata and Physalis pubescens in the Valley of Mexico

The processes and mechanisms that determine the growth and yield of crops in different environments are necessary to increase agricultural production, since they guide us in the choice of the most appropriate management practices. The aim of the study was to evaluate, during the years 2018, 2019, 2020, the performance of Physalis philadelphica, Physalis angulata and Physalis pubescens as a function of leaf area index, light extinction coefficient and radiation use efficiency. Research was carried out at the Center of Research and Advanced Studies of the Autonomous University of the State of Mexico. Results revealed that the environmental conditions of 2018 positively influenced the expression of leaf area index and radiation use efficiency, increasing the average production of Physalis sp. (10.65 t/ha) compared to 2019 (9.67 t/ha) and 2020 (8.13 t/ha). P. philadelphica produced the greatest amount of fruit (16.69 t/ha), followed by P. angulata (10.46 t/ha) and P. pubescens (1.33 t/ha). Genotype environment interaction in 2018 stimulated the expression of the eco-physiological attributes of P. philadelphica, achieving a yield of 18.83 t/ha.
