The root morphology of new czech lucerne candivars

Original language description

The aim of this paper was to compare root morphology of three new Czech lucerne candivars with the standard variety Jarka under different levels of soil compaction. Three candivars with different ratio of American pasture lucerne varieties in their origin were used. Plot experiment was established in split plot design with four replications: variant 1 and 2 with average soil bulk density 1.39 g.cm-3 and 1.51 g.cm-3, respectively. These parameters were measured: tap-root diameter under crown (TD), lateral root number (LRN), lateral root diameter (LRD) and lateral root position (LRP) of plants sampled in spring and autumn period. The TD value was in positive correlation with LRN and LRD and all these were negatively correlated with the stand density. Only candivar XLII proved significantly lower TD in comparison with the standard variety Jarka, but this trait was not connected with more branched root or higher persistence. Significantly lower LRN was observed for all candivars; low reach
