Rhododendron - Opis:
- High content of calcium compounds in soil limits cultivation possibilities of the majority of cultivars of rhododendron. In the research presented an attempt was made to determine the influence of a high level of calcium salts CaCl2, CaSO4, Ca(NO3)2 and CaCO3, pH and an increased level of auxins in a medium, on the development of microcuttings of R. ‘Catawbiense Grandiflorum'. On the basis of the results of the research it is justifiable to state that it was the anions of some salts used that had an adverse effect on the development of rhododendron cultures, not calcium cations. Significant differences were noted in the uptake of calcium, magnesium and sodium ions by the microcuttings depending on salts used in the media. The pH value of the medium higher than optimum significantly affected the degree of chlorosis of the microcuttings analyzed. Supplementing the media with additional auxin - IBA was stimulating for the plant growth especially in the medium containing CaCO3.
