Shelf life and quality of ber (Zizyphus mauritiana Lamk.) fruit cv. Umran in response to post harvest application of ultraviolet radiation and paclobutrazol.

摘要

Effect of post-harvest application of UV radiation and paclobutrazol (PBZ) on shelf life and quality of ber fruits (jujubes, Zizyphus mauritiana) was studied. Physiological loss in wt. (PLW) and rotting were lowest in fruits treated with UV radiation (for 6 h) + PBZ (5 ppm), during 12 days of storage. As the storage period advanced, TSS and TSS/acid ratio increased, while acidity and ascorbic acid contents of the fruits decreased. Highest ascorbic acid (86.19 mg/100 ml juice) and lowest TSS (16.16%) were retained in fruits treated with UV radiation for 6 h + PBZ (5 ppm).
