Effect of Polyethylene on Fruit Yield and Morpho-Biochemical Features During Ripening of a Local Tomato Cultivar Grown in a Tropical Environmental Condition, India

摘要

The work was assessed the field performance of Polythene cover on morphology, fruit yield and post maturation changes on growing tomato(Lycopersicon esculentumJ.Data. revealed that use of polythene gave adverse effect on average height in treated condition but favorable for matured ripen fruits(41.5%). Significant correlation observed in the post maturation(0.731, Pd”0.01) and fruits ripening time (0.605, Pd”0.01) .The fruit yield was found to be significantly increased by 61.23% .Polythene inducedripening had shown the variation in the amount of lycopene (429.3mg/100gm), protein (1.92%), ascorbic acid (23.68 mg/ 100gm) and the sugar(5.02%). Polythene covering was significant and positively correlated with lycopene(0.788, P<0.01),lipid(0.853, P<0.01),ascorbic acid(0.515 P<0.01) but negatively correlated with protein(-0.221P<0.05).Maturity at harvest is a very important attribute to tomatoes quality that found to be regulated by the use of polythene. Analysis of variance also showed statisticallysignificant result in the lipid (F-value=14.688801,pd”0.01) ,sugar(F value= 25.52718,pd”0.01) and ascorbic acid (F-value=9.44343,pd”0.01).
