abstract
Apple ber (Zizyphus mauritiana) is a Thailand variety ber belongs to the family Rhamnaceae. Apple ber is developed by grafting Thailand green apple with Thai local ber. In the studies conducted on the effect of surface coatings and packaging materials on quality of Apple ber (Zizyphus mauritiana) at different storage conditions at College of Horticulture- Rajendranagar, SKLTSHU, Rajendranagar. The experiment was conducted in two factor completely randomized design with three replications in which factor one includes nine treatments of surface coatings and packaging materials along with control (without any surface coating and packaging). Factor two includes two storage condition S₁-cold storage (10±2ºC) and S₂-room temperature (22±2ºC) and observations were recorded at 3 days interval upto end of shelf life of fruits. Highest ascorbic acid content (61.20) and total sugars (14.40) was recorded by P₄S₁. Among the treatments Chitosan 1% + HDPE (High Density Polyethylene) is best followed by Chitosan 1% + PP (Polypropylene). Among both storage conditions fruits stored in cold storage (10±2ºC) gave better results. In interaction effects Chitosan 1% + HDPE (High Density Polyethylene) + cold storage (10±2ºC) is best of all the treatments followed by Chitosan 1% + PP (Polypropylene) + cold storage.
