Enhance the longevity and aesthetic appeal of Anthurium andraeanum cv. Fire cut leaves by using some natural components.

This experiment was conducted to examine the effects of rosehip oil (Rh oil), Arabic gum (AG), and chitosan (CS) on the vase life and quality of Anthurium andraeanum cv. Fire under laboratory conditions. The experimental layout followed a completely randomized design. Seven treatments were applied: tap water (control), Rh oil (2% or 4%), Rh oil (2% or 4%) + AG (5%), and Rh oil (2% or 4%) + AG (5%) + CS (500 ppm). The leaves were sprayed using a hand sprayer until runoff occurred. Results showed that the highest increases in vase life, final water uptake, chlorophyll a and b content, and the degree of leaf health and glossiness were obtained after the application of 4% Rh oil. Scanning electron micrographs illustrated that stomata were open in untreated leaves, moderately open after application of 2% Rh oil, slightly open after spraying with 4% Rh oil, and completely closed after the application of Rh oil (2% or 4%) + AG (5%).
