Enhancing fruit quality of cold-stressed physalis peruviana during late-season through spraying with phenylalanine, cysteine, and selenium.

ABSTRACT:

Background

Low temperatures are a significant environmental factor that can adversely impact the growth and productivity of tropical plants, such as Cape gooseberry (Physalis peruviana L.). In the current experiment, the foliar application of amino acids L-phenylalanine (Phe), L-cysteine (Cys), or sodium selenite (Se) was investigated on qualitative and biochemical properties of Cape gooseberry fruits subjected to low temperature condition in 2-year field experiment (2021 and 2022).

Results

Our findings indicated that low temperature stress reduced membrane stability index and vitamin C content of fruits in comparison to the control plants in both years. Nonetheless, MDA, H2O2 and antioxidant enzymes activity meaningfully enhanced as a consequence of low temperature conditio
