2007 m. Nr. 2 Adaptation of American cranberry to substrate pH
in vitro and ex vitro
The aim of the present work was to investigate the properties of physiological and morphological changes during adaptation of American cranberry (Oxycoccus macrocarpus (Aiton) Pursh) to nonoptimal acidity of the substrate in vitro and ex vitro. The investigation was carried out with three cranberry cultivars: ‘Bergman’, ‘Bain 10’ and ‘Black Weil’. Changes in the morphological parts of plants during adaptation were measured. The content of mono-carbohydrates in microshoots growing in media of different acidity was evaluated by high-pressure liquid chromatography.
‘Bergman’ and ‘Black Weil’ were found to be more adaptive than ‘Bain 10’ to the pH of the substrate. The content of mono-carbohydrates in microshoots depended on the acidity of the medium. The pH of the substrate influenced microshoot growth and the pigmental system of photosynthesis in plants. Cranberry plants tolerate a more alkaline pH when growing in vitro than ex vitro.
