Ethylene and maturation retardants in the postharvest of perishable horticultural products. A review. rev.colomb.cienc.hortic. [online]. 2014, vol.8, n.2, pp.302-313. ISSN 2011-2173.

Ethylene is the plant hormone responsible for regulating various processes during the ripening of agricultural products, leading to a senescence process and, finally, to a loss of the nutritional and commercial values. Over time, different chemical maturation retardants have been developed to decrease the negative effects of ethylene, which act on the stages of biosynthesis (aminoethoxy-vinyl-glycine (AVG) and aminooxyacetic acid (AOA), action/signaling (1-methylcyclopropene (1-MCP)) and silver salts, such as nitrate and silver thiosulfate (STS) and compounds that oxidize the ethylene of the atmosphere (potassium permanganate (KMnO₄). In this review, the main characteristics of each chemical retardant are discussed along with the scientific studies on the effects of these retardants on the molecular, physiological, chemical and physical changes during the postharvest of fruits, vegetables and ornamental species.
