The root morphology of new Czech lucerne candivars in relation to stand density

Original language description

The root system morphology of alfalfa is in the relation with plant persistency as well as yield and quality of dry matter. The aim of this study was compare the tap-root diameter and ratio of plants with branching root system among five new Czech alfalfa candivars and control variety Jarka. In spring 2003, the plot experiment with evaluated candivars was established in the field of the Czech University of Agriculture Prague in Suchdol in complete randomized blocks. In 2003 ? 2006, the samples of plantswere taken in each autumn from squares 30 x 30 cm with four replications per each alfalfa entries. The plants number, tap-root diameter, and ratio of root branching plants were assessed by each sample. Stand density decreased from 650 pcs.m-2 in 2003 to100 pcs.m-2 in 2006. Tap-root diameter was significantly positively correlated with root branching and negatively with stand density. When effect of density was excluded as covariate, the highest taproot diameter provided Jarka and candi
