Název v původním jazyce

In-field lucerne root morphology traits over time in relation to forage yield, plant density, and root disease under two cutting managements

Popis výsledku v původním jazyce

Our objectives were: (i) to compare lucerne root trait development under three- and four-cut managements over a 4-year period, and (ii) to investigate relationships among root traits, and between root traits and lucerne varieties, cutting frequencies, root sampling periods, lucerne dry matter yield and evidence of root disease incidence and plant density, using multivariate methods. Root morphology traits were strongly modified by sampling period and plant density, which together explained over 40 % of total variability. The development over time was positively associated with an increase in tap-root diameter (TD) and root mass accumulation, whereas root density determined changes in root branching traits. The four-cut management reduced TD and root branching in association with lower forage yield. Variety effect was significant but contributed only 2,8 % of total variability. Root branching showed a positive correlation with forage yield through a large increase of TD for branch-rooted plants, but m
