Cięte liście funkii stosowane są jako zielony dodatek do bukietów. W doświadczeniach sprawdzono wpływ benzyloadeniny (BA), kwasu giberelinowego (GA₃) oraz cytrynianiu 8-hydroksychinoliny (8HQC) i 8HQC z dodatkiem 2% sacharozy (S), (pożywka stosowana standardowo do przedłużania trwałości kwiatów ciętych) na podstawowe procesy zachodzące podczas starzenia ciętych liści funkii, tj. degradację białek,...
Cut leaves of Zantedeschia aethiopica Spr. and Hosta ‘Undulata Erromena’ are widely used as the florists’ green. Effect of pulsing leaves with growth regulators and a storage method (dry or wet, in light or darkness, at 5°C) on postharvest longevity and chlorophyll content was investigated. Leaf vase life after 3 days storage was evaluated at 20°C and 12 h light/12 h night. Results confirmed that...
Cut leaves of Zantedeschia aethiopica and Z. elliottiana are widely used as the florists’green. Over the years we studied the parameters related to postharvest quality of leaves in the two above species. Here the effect of plant hormones known to delay leaf senescence (benzyladenine and gibberellic acid) and of the standard preservative solution (8-HQC + 2% sucrose) on the reducing sugars contents...
Proteolysis and free amino acid accumulation occur during leaf senescence. As senescence is under control of plant hormones leaves of Zantedeschia aethiopica Spr. and Zantedeschia elliottiana Engl., two species grown for the florists’ green, were pulse treated 24 hours with solutions of benzyladenine or gibberellic acid (0.1 mmol·dm⁻³ and 0.25 mmol·dm⁻³, respectively) in order to delay senescence...
Chlorophyll degradation occurring during leaf senescence in under control of plant hormones. Changes in the chlorophyll content and the effects of BA (benzyladenine) and GA₃ (gibberellic acid) on this process were analyzed during senescence of cut leaves of Zantedeschia aethiopica Spr. and Zantedeschia elliottiana Engl., two species grown for the florists’ green. Both growth regulators were applied...
