Effect of Different Coloured Plastics and Liners on Shelf Life of Loose Marigold Flowers

A study was carried to evaluate the effect of different coloured plastics and liners on shelf-life of loose marigold flower under ambient condition was at the laboratory of the Department of Floriculture and Landscape Architecture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, during the year 2021–2022. The experiment was laid out in Complete Randomized Design with 3 replication and 16 treatments. The treatment comprised of different coloured plastics (Red, Opaque, Transparent and Green) and liners (Paper cutting, Paper straw and Bubble film) in different combination including control. The results revealed that among all the combination of different coloured plastics and different liners used treatment T₇ (Transparent + Paddy straw) showed better quality in all parameters like physiological weight loss(2.26%, 34.20% and 47.10%), moisture content(82.33%,71.72% and55.01%), spoilage percentage(5.10%,12.37% and 25.19%), diameter of flower (5.81cm, 5.09cmand 4.40 cm), freshness index(4.68, 3.98 and 3.11 out of 5 score card), relative water content(83.00%,74.00% and 55.66%), shelf life(2.35 days) at 2^nd, 4^th and 6^th days after storage respectively. When the spoilage of flower exceeded 50 percent, it was considered as the end of shelf life or storage life.
