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. |
