Vliv vodního stresu na výnosové a jakostní parametry zeleniny

The two-year experiment (2010, 2011) dealt with the evaluation of yield and quality parameters of vegetables Capsicum annuum L., variety 'SLÁVY F1' and Allium porrum L., 'GIGANTE SUIZO' treated with mycorrhizal product SYMBIVIT in two irrigation modes. The research was conducted as a field experiment. The site was located on the properties of Faculty of Horticulture MENDELU, Mendeleum, Lednice. The positive effect of the mycorrhizal preparation as an intensifying factor was statistically proven in the quality of pepper seedlings. The set parameters were: plant height, stem diameter and increase of the number of leaves. The set parametres in the quality of leek seedlings were: stem diameter, length of the above-ground part, the length of the underground section, weight of fresh roots, weight of roots after drying. The positive effect of the mycorrhizal preparation as an anti-stress measure was proven in the evaluation of yield of peppers in 2011. The positive effect of the mycorrhizal preparation as an anti-stress measure was also proven in the evaluation of yield of the 1st grade quality of peppers in 2011 and in the quantity of nitrates in leek planted in 2010. The positive effect of mycorrhizal preparation as an intensifying factor or as an anti-stress measure on the other evaluated parameters was not proven
