Effect of mycorrhization on the flowering of the Zantedeschia albomaculata /Hook./ Baill. cv. Albomaculata

Abstract

The study involved the application of a top dressing of a multicomponent Peters Professional fertiliser at concentration of 100 and 200 mg/l in the amount of 100 ml/plant, once every 7 days regardless of the fact whether the rhizomes had been mycorrhized before or not. Mycorrhization caused an increase in the quality of flowers, as expressed by peduncle length and their yield in Zantedeschia albomaculata cv. Albomaculata at both levels of top dressing, which shows that it is possible to reduce the top dressing dosage to a concentration of 100 mg/l. Mycorrhization had a favourable effect on the accumulation of nitrogen and manganese in the leaves of the calla lily. In mycorrhized plants the mean nitrogen content in 12 leaves ranged between 5.35 and 5.55% d.w. Mycorrhized plants accumulated more manganese in19 their leaves irrespective of the level of top dressing.
