The research was conducted on two cultivars of Sinningia speciosa (Lodd.) Hiern: ‘Defiance’ and ‘Blanche de Meru’. Plants were cultivated with or without symbiosis with endomycorrhizal fungi. In order to evaluate the biochemical changes in the leaves of Sinningia speciosa at the vegetative growth stage the content of chlorophyll a+b, carotenoids, protein and saccharides was determined. Plant growth...
Rhizomes of Zantedeschia, 15-18 cm in circumference with leaf buds 0.5-1 cm in length, were planted into 20-cm pots on 15 May 2006 into a medium consisting of peat with a pH of 6.2, enriched with a slow-release fertiliser Osmocote Plus (3-4M) and mixed with fresh shredded pine bark at a rate of 3:1 (v:v). Before planting, the rhizomes were soaked for 20 minutes in a water solution of gibberellic acid...
Kondycjonowanie liści obrazków włoskich, w wodnych roztworach siarczanu 8-hydroksychinoliny (8HQS) o stężeniu 200 mg‧dm⁻³ i kwasu giberelinowego (GA₃) o stężeniu 100 mg‧mg⁻³, trwało 4 godziny. Następnie liście umieszczono w wodzie lub w wodnych roztworach benzyloadeniny (BA) o stężeniu 50 i 100 mg‧dm⁻³. Kontrolę stanowiły liście umieszczone w wodzie. Trwałość obrazków włoskich wyniosła około dwóch...
Growth regulators used in the experiment had a mixed effect on morphological features of twinspur (Diascia barberae L.) plants and their response depended on type and concentration of applied retardant and on the cultivar. In the cultivar ’Diastu’ the biggest number of shoots was found in plants treated with daminozide at concentration of 2550 mg‧dm⁻³ and with 700 mg‧dm⁻³ chlormequat. In cultivar...
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...
