Premature leaf yellowing of Alstroemeria cut flowers prior to petal fall is the most important limiting factor of the flower postharvest life. In this study, cut flower Alstroemeria cv. Bridal were treated for 24 hours with different solutions including gibberllic acid, benzyl adenine, natural essential oil carvacrol with two concentrations of 50 and 100 mg L-1, 5-sulfo salicylic acid in two co...
Tuberose (Polianthes tuberosa) is one of the most important cut flowers with fragrant buds. To prolong vase life of tuberose, proper preservative solution applying is necessary. For this purpose, two types of chemical and natural treatments were used. Applied treatments were benzyladenine (50, 100, and 150 mg l-1), the extracts of rosemary and Eucalyptus (12, 25 and 50%) and sour orange fruit e...
nickel and cadmium are heavy metals with some hazards for plant metabolism. the impacts of nickel chloride (0, 400 and 800 μm) in the presence of vitamin b complex (0, 30 and 60 ml from pharmacy commercial stock) and the impacts of cadmium chloride (0, 100, 200, 300, 400, 500 and 600 μl from 100 µm stock) in pot and cadmium nitrate (0, 100, 200, 400, 800, 1600 and 3200 μl from 100 µm stock) in ...
Chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. In order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a RCD with 10 treatments: Artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), Ri...
