Effect of preparations from the Chrysal series and benzyladenine on the postharvest longevity of shoots of the St. John’s wort (Hypericum calycinum L.)
Abstract.
The conditioning of shoots of the St. John’s wort (Hypericum calycinum) in solutions of the Chrysal RVB and Chrysal Clear RVB preparations before placing them in water extended their postharvest longevity by 17.3 and 16.4 days, respectively. Benzyladenine at concentrations of 50 and 100 mg/dm3 decreased the postharvest longevity of the H. calycinum. Chrysal RVB and Chrysal Clear RVB contributed to a higher index of leaf greenness.
Keywords: vase life, preservatives, florists’ green, index of leaf greenness
