The effect of preservatives and growth regulators benzyladenine (BA) and gibberellic acid (GA3) on longevity of cut shoots of Molucella laevis L. was studied. Solution of 200 ppm citrate 8-hydroxychinoline (8 HQC) with 2% sucrose (S), routinely used to prolong the vase life of cut flowers, negatively affected the longevity of bells of Ireland. Several products of POKON & CHRYSAL were tested of which the Chrysal SVB® proved to be the best for shoot pulsing. BA and GA3 reduced vase life in comparison with water controls. Degradation of chlorophyll proceeded faster in the lower calices than in the upper ones and depended on chemicals in a vase solution.
