Abstract:
Perennial, herbaceous and semi-woody plants, intrinsic part of florist industry notwithstanding of plant families are incorporated predominantly into foliage plants category, abstemious handling of which concerning their worthy post harvest features may lead implementation in both landscaping and interiorscaping. The intent of present investigation was to showcase the consequence of 50 and 100 ppm of NAA, 50 and 100 ppm of GA3, 20 and 40 ppm of AgNO3 and 4% and 8% of sucrose as vase solution for 24, 48, 96 and 120 hours durational treatment on full-grown palm leaves of Chrysalidocarpus lutescens, Raphis excelsa and Caryota mitis to sustain and extend their post harvest life. Water uptake and fresh weight increase and decrease were disproportionate with consecutive 120 hours treatment in each cut foliage except the hike of 13.1 g of fresh weight and 3.1 ml of water uptake noted in Raphis excelsa and Caryota mitis after 48 hours of imbibitions respectively. In case of Chrysalidocarpus lutescens and Caryota mitis AgNO3 at 20 ppm proved itself best for prolonging vase life of 35.1 and 54.7 days respectively while AgNO3 at 40 ppm exhibited satisfactory result of 15.6 days vase life in Caryota mitis. Surprisingly, 35.1 days of vase life obtained after GA3 at 40 ppm treatment in Chrysalidocarpus lutescens in lieu of 14.1 days vase life under control. Here, three cut foliages manifested different responses regarding increase/decrease of their chlorophyll content but significantly high amount of chlorophyll viz. 119.05 and 73.68 mg/100g were secured under control and NAA at 50 ppm treatment in Chrysalidocarpus lutescens and Caryota mitis. Water uptake and water loss in treated shoots in holding solutions were failed to establish any relation with vase life.
