Defense enzyme activities and biochemical variations of Pelargonium zonale in response to nanosilver application and dark storage

Pelargonium petal abscission and ethylene-induced leaf senescence are major problems that reduce the longevity of plants. This study was carried out to determine the poststorage influence of nanosilver (NS) particle (0, 20, 40, 60, and 80 mg L–1) application during dark storage period on chlorophyll and carotenoid pigments, malondialdehyde (MDA) content.
