INFLUENCE OF SODIUM CHLORIDE ONTO GROWTH AND FLOWERING OF ISOTOMA AXILLARIS LINDL.

M. U.-Walorska, A. Krzymińska

Abstract: To assess the effect of sodium chloride on growth and flowering of Isotoma axillaris their plants grew in pots filled with peat substrate and with sodium chloride. In 2011 the following dosages of sodium chloride were applied: 0, 5, 10, and 15 g.dm-3. In 2012 the dosages of sodium chloride were increased, and the following amounts were applied respectively: 0, 10, 20, and 30 g.dm-3. The presence of sodium chloride in the substrate diminished decorative qualities of the species under study, which included growth and flowering inhibition together with the decrease in the index of leaves greenness. Moreover, both the fresh and the dry matter of the plants decreased together with the increase in sodium chloride concentration in the substrate. This compound had also a negative influence onto the water percentage in the plants.
