Influence of post-harvest application of ethrel and paper wrapping on physical parameter and ripening of papaya (Carica papaya l.) Cv. Madhu Bindu

Abstract

Papaya (Carica papaya L.) is an important and a very popular fruit crop of the tropical and subtropical areas in the world. The experiment was conducted to study the “influence of post-harvest application of ethrel and paper wrapping on papaya (Carica papaya L.) cv. Madhu Bindu” during kharif, 2017 at Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand(Gujarat). The experiment was framed in completely Randomized Design with factorial concept replicated thrice with ten treatment combination. The treatment were comprised of five different concentration of ethrel (0 mg/l, 500 mg/l, 750 mg/l, 1000 mg/l and 1250 mg/l) along with paper wrapping (with paper wrapping and without paper wrapping). Fruit dipped in ethrel @ 1250 mg/l shows early ripening. Significantly minimum PLW (%) and spoilage (%) while, maximum firmness and shelf life were observed with no-ethrel treatment (0 mg/l). In case of paper wrapping significantly maximum firmness, minimum PLW and early ripening was observed with paper wrapping while, significantly minimum spoilage and long shelf life was observed in non-wrapped fruit.
