| Abstract : | 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 parameters, such as height, diameter, number of leaves and number of initiated flower buds, were determined when first flower was developed. Mycorrhizal plants of Sinningia ’Defiance’ and ‘Blanche de Meru’ had more flower buds, 66.7 and 57.1%, respectively. Themycorrhization had a positive influence on the content of chlorophyll a+b in the leaves of Sinningia speciosa ‘Defiance’, whereas in the Blanche de Meru cultivar this dependence was observed only in the ninth and tenth week of cultivation. At the vegetative stage the mycorrhized plants had a higher content of carotenoids in their leaves, except for the tenth week of cultivation in the Defiance and the seventh and tenth weeks of cultivation in the Blanche de Meru cultivar. Themycorrhization did not influence the content of protein in the cultivars under investigation, except for the ninth week of cultivation. The highest content of saccharides in the leaves of Defiance and Blanche de Meru cultivars was noted at the beginning of vegetation and it was similar in the mycorrhized and non-mycorrhized plants. |
