Online Published on 20 December, 2022. Abstract The investigations on postharvest handling of chrysanthemum (Dendranthema grandiflora Tzvelve) culivars Solan Shringar and Yellow Star were carried out at the Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. Studies included the effect of TDZ on reduction of leaf yellowing in dry storage of selected cultivars. Experiments were conducted in a completely randomized design (factorial). Effect of foliar spray of thiadiazuron on cut foliage successfully retained the green colour and showed maximum vase life and appearance when treated with TDZ (150 µM) and dry stored at 4ºC for 5 days than those stored for longer durations. In general, better postharvest longevity was observed in cultivar Yellow Star than Solan Shringar. Top Keywords Chrysanthemum, Thidiazuron, Solan Shringar, Yellow Star, Leaf yellowing, Dry storage.
