Effect of conditioning in gibberellic acid and benzyladenine on postharvest longevity of leaves of the Italian arum (Arum italicum Mill.)
Summary.

The aim of the experiment was to evaluate the effect of two conditioning methods in solution of gibberellic acid and benzyladenine on postharvest longevity of Arum italicum leaves. The solutions of GA3 and BA in concentrations of 25 and 50 mg·dm-3 were used in two ways: 24 h conditioning of leaves in cold room in temperature 5°C and few seconds soaking of leaf blades. After the conditioning leaves were placed in distilled water. The postharvest longevity of leaves was 3 weeks. Few seconds and 24 h conditioning soaking in solution of GA3 enhanced the postharvest longevity of leaves, but 24 h conditioning in solution of GA3 in concentrations of 25 and 50 mg·dm-3 was effective and extended the postharvest longevity for about 2 weeks. Conditioning in solution of BA in concentrations of 25 and 50 mg·dm-3 had a slight effect on extension of postharvest longevity of leaves. Soaking of leaf blades in solution of benzyladenine was ineffective. Gibberellic acid and benzyladenine did not inhibit the decline of leaf greenness index.
