Fig. 2.

Leaf mass fraction of the harvestable biomass (>5 cm above ground; LMFH) in the course of the experiment. Each dot refers to the pooled LMFH of five plants per pot. The linear regression models are represented as lines. For statistical details see Table 3. Onobrychis: commercial seed (open circles dashed line) and ‘Visnovsky’ (filled circles solid line). Lotus: ‘Oberhaunstädter’ (open circles dashed line) and ‘Lotar’ (filled circles solid line). Cichorium: ‘Puna’ (open circles) which did not produce stems during the entire experiment and ‘Lacerta’ (filled circles solid line).
