Doświadczenie przeprowadzono w latach 2000-2001. Kłącza cantedeskii Elliota 'Black Magie' sadzono do ażurowych skrzynek wypełnionych substratem torfowo-korowym. Przed sadzeniem kłącza moczono w wodnych roztworach kwasu giberelinowego o stężeniu 0, 50, 100 i 150 mg·dm3. Wykazano istotny wpływ kwasu giberelinowego na kwitnienie roślin. Było ono dłuższe, ale znacznie późniejsze. Plon kwiatów wzrastał wraz ze zwiększającym się stężeniem kwasu giberelinowego. Największy plon uzyskano dzięki moczeniu kłączy w roztworze o stężeniu 150 mg(GA3)·dm3 . Nie stwierdzono następczego wpływy kwasu giberelinowego na trwałość kwiatów po ścięciu.

Do sterylizacji eksplantatów merystematycznych wyizolowanych z bulwiastych kłączy trzech odmian cantedeskii Elliota wykorzystano ACE, Domestos oraz 3% techniczny podchloryn sodu. Przeprowadzono również sterylizację metodą Cohen'a stosując 95% etanol. Zregenerowane pędy namnażano na pożywce Murashige'a i Skoog z benzyloadeniną w stężeniach 1, 3 i 5 mg·dm³. Przed ukorzenieniem stężenie benzyloadeniny obniżono do 0,3 mgdirr3, a przy ukorzenianiu - do 0,1 mg·dm³ . Najlepszym środkiem sterylizującym okazał się 50% АСЕ stosowany przez 20 min. Najwyższy współczynnik namnażania pędów uzyskano na pożywce zawierającej benzyloadeninę w stężeniu 3 mg·dm³. Wyższe stężenie tego regulatora wzrostu powodowało później znaczne zahamowanie procesu tworzenia się korzeni.

Over 2000–2001 the Department of Ornamental Plants in Poznań carried out two experiments which aimed at defining the effect of the gibberellic acid on post-harvest leaf quality of Zantedeschia elliottiana (W.Wats.) Engl.: ‘Florex Gold’ and ‘Black Magic’. The leaves were conditioned and stored. Conditioning, in water solutions of Gibrescol at the concentration of 100, 200 and 300 mg·1⁻¹ took 20 hours. Conditioning involved the application of Gibrescol which contained 98% of the gibberellic acid (GA₃). Then the leaves were placed into water or into preservative solutions: 8HQC or 8HQS at the concentration of 200 mg·1⁻¹. The post-harvest leaf quality was defined in the growing room at the temperature of 18–20°C at 12-hour photoperiod and inflorescence light of the quantum irradiance of 25 µmol·m⁻²·s⁻¹, while the air relative humidity was maintained at 70%. Stored leaves lost their decorative values little by little. Tips and margins of leaf blades were dried. Decrease of leaf weight and length of leaf petiole was also observed. The preservative solutions 8HQC and 8HQS significantly decreased the post-harvest quality of leaves.

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 is presented. BA (0.1 mmol·dm⁻³) and GA3 (0.25 mmol·dm⁻³) were applied as 24 h pulse treatments. Pulsed and unpulsed leaves were kept either in water or in the preservative. In both species contents of reducing sugars during their senescence in vases initially rose and then dropped to 60–80% of the initial levels. Pretreatment with BA did not counteract a decrease in reducing sugar contents while in the GA₃-treated leaves sugar loss was prevented in Z. aethiopica and a 20% increase occurred in Z. elliottiana. Placing leaves in the sugar containing solution provoked a dramatic loss of reducing sugars in Z. aethiopica (to 12% of the initial level) while in Z. elliottiana this loss was less pronounced (52% of the initial value). Cytokinin did not mitigate the negative effect of the preservative on reducing sugar losses while GA₃ was more effective in this respect. Results of analyses do not support hypothesis that sugar depletion might be a cause of senescence of detached leaves in the two Zantedeschia species.

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 as 24 h pulse treatment: 0.25 mmol·dm⁻³ and 0.1 mmol·dm⁻³ for GA₃ and BA, respectively. Gibberellic acid was more effective than benzyladenine in delaying senescence of both Zantedeschia species leaves by retarding chlorophyll loss. A standard preservative solution used to prolong longevity of cut flowers (8-HQC /citrate of hydroxyquinoline/ +2% S /sucrose/) radically accelerated chlorophyll loss of Z. aethiopica leaves but had no effect on pigment degradation in leaves of Z. elliottiana. However, in both species the preservative diminished the positive effect of GA₃ treatment on final chlorophyll content.

Two experiments were carried out to determine the effect of gibberellic acid on the longevity of cut flowers of two Zantedeschia elliottiana (W. Wats./Engl.) cultivars: 'Black Magic' and 'Florex Gold'. The flowers were conditioned for 2, 4 and 20 hours in water solutions of 8-hydroxyquinoline citrate at concentrations of 200 mg l⁻¹, and then kept in water and gibberellic acid solutions at concentrations of 50 and 100 mg l⁻¹. Gibberellic acid enhanced the post-harvest longevity of Z. elliottiana flowers. Those of the 'Black Magic' cultivar lasted the longest when not conditioned, but merely stored in gibberellic acid solutions. 8-hydroxyquinoline citrate shortened their longevity by a week.The post-harvest longevity of flowers of the 'Florex Gold' cultivar significantly depended on the concentration of gibberellic acid and conditioning time. The longest-lasting flowers were those conditioned in 8-hydroxyquinoline citrate for 2 hours.

Kwas giberelinowy zastosowano przed ukorzenianiem mikrosadzonek pędowych dwóch odmian cantedeskii Elliota ‘Sensation’ i ‘Treasure’, zregenerowanych in vitro z eksplantatów merystematycznych wyizolowanych z bulwiastych kłączy. Wprowadzono go w stężeniu 50 mg·dm⁻³ do pożywki Murashige’a i Skoog (1962), zestalonej agarem i uzupełnionej kwasem indolilo-3-octowym 10 mg·dm⁻³ i benzyloadeniną 0,1 mg·dm⁻³. Obserwowano następnie, w trzech kolejnych sezonach wegetacyjnych, następczy wpływ GA₃ na wielkość i masę kłączy oraz liczbę i kształt liści. W trzecim roku uprawy obserwowano wpływ GA₃ na kwitnienie roślin.

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 and to prolong their vase life. GA₃ but not BA retarded proteolysis in both species. A standard preservative solution used to prolong the longevity of cut (8-HQC + 2% S; 8-hydroxyquinoline citrate + 2% sucrose) accelerated proteolysis in the Z. aethiopica leaves but had no effect on leaves of Z. elliottiana. Soluble protein losses were accompanied by elevated levels of free amino acids, however, range of these increases did not correspond to decreases in protein contents. A massive accumulation of free amino acids occurred in the sugar-fed leaves of both species. Growth regulators somewhat limited free amino acid accumulation in leaves held in the preservative, BA being more effective in Z. elliottiana while GA₃ in Z. aethiopica.
