Abstract
The research carried out under greenhouse and field conditions involved three species and eight cultivars representing genus Festuca (F. arundinacea, F. rubra, F. ovina). The research results showed that semi-drought reduces the weight and the length of roots less considerably than of their aboveground parts. The research of the sod regeneration level showed that the process is species-specific. The lowest tolerance to semi-drought is observed for F. rubra cultivars, while those most resistant to drying-off are F. ovina cultivars. The grasses which, after the period of semi-drought, regenerated the sod most considerably were F. ovina cultivars. The coefficient of correlation calculated showed that for the grasses evaluated, depending on the species, under greenhouse and field conditions, the morphological characteristics of roots (weight and length) are a good indicator of the reactions of the grasses investigated to the process of sod drying-off and regeneration. The results of research reported in the greenhouse experiment, especially for F. rubra, are confirmed in the field conditions.
