Opis:
Plants of ‘Catawbiense Boursault’ and ‘Eskimo’ rhododendrons or ‘Cannon’s Double’ and ‘Kilian’ azalea grown in 4 l containers were treated twice with chlormequat (2000, 4000 and 8000 mg · dm-3), trinexapac-ethyl (50, 100, 200, 400 mg · dm-3), daminozide (2500, 5000, 7500 mg · dm-3), proxeadione calcium (75, 150, 300 mg · dm-1) and once with paclobutrazol (50, 100, 200, 400 mg · dm-3). Shoot length of the subsequent growth flush following the treatments decreased with increasing rates of the growth retardants. The number of flower buds per plant increased with increasing rates of pacloburazol, chlormequat and daminozide. Prohexadione calcium was less effective in flower bud initiation and the worst results were obtained with trinexapac-ethyl.

Opis:
For proper growth and development, rhododendrons need acidic soils, whereas calcium carbonate (CaCO3) in the substrate markedly limits their growth. In this study, we analysed the reactions of rhododendrons to high concentrations of calcium salts and pH in the substrate. We used 4-month-old seedlings of Rhododendron ‘Cunningham’s White’ and 1.5-year-old seedlings and rooted cuttings of R. ‘Cunningham’s White’ and R. ‘Catawbiense Grandiflorum’. Their reactions depended mostly on calcium salt type added to the substrate (sulphate or carbonate). An increase in concentrations of phenolic compounds was detected mostly in roots of the plants grown in a substrate with a high calcium carbonate content. Addition of calcium salts to the substrate caused a significant rise in total nonstructural carbohydrates in leaves and roots of the studied plants. As compared to the control, an increase in substrate pH in the variant with calcium carbonate limited the activity of acid phosphatase, while lowering of substrate pH in the variant with calcium sulphate, significantly increased its activity. Along with the rise in substrate pH, a remarkable increase was observed in the activity of nonspecific dehydrogenase (DHA) in the substrate with CaCO3, as compared to the control. Unfavourable soil conditions (high calcium content and alkaline pH) caused a decrease in assimilation of minerals by the studied plants (mostly phosphorus and manganese). Our results show that the major factor limiting rhododendron growth is an increase in substrate pH, rather than an increase in the concentration of calcium ions.
