Figures & data
Table 1. Matched pairs of historical and modern cultivars based on leaf size class and growth habits. Date of cultivar release in parentheses.
Table 2. Mean shoot dry weights (mg) of six white clover cultivars inoculated with each of six rhizobia strains.
Table 3. Mean number of nodules for six white clover cultivars across each inoculant treatment.
Table 4. Mean shoot dry weights of white clover cultivars when inoculated with rhizobia strain mixtures in Experiment 2. Within column values with the same letters are not significantly different at P < 0.05.
Table 5. The number of nodules occupied by each strain of rhizobia for each of the six cultivars of white clover.
Figure 1. The relationship between nodule occupancy and cultivar × strain SDW (Experiment 1) for historic (n = 3) and modern (n = 3) cultivars of white clover. Data points for historical cultivars are black and modern cultivars are purple. Trend lines are coloured accordingly and are fitted from the generalized linear mixed effect model.
Figure 2. The relationship between nodule occupancy and cultivar × strain SDW (Experiment 1) for all six cultivars of white clover. Modern cultivars are in purple and historical cultivars are in black. Each pair of modern and historical cultivars is represented by the same shape (Crusader and Irrigation = square, Tribute and Huia = circle, Kopu II and Louisiana = triangle). Trend lines are coloured according to cultivar age (historical back, modern purple) and are fitted from the generalised linear model. Each pair of modern and historical cultivar have the same trend line style (Crusader and Irrigation = solid line, Tribute and Huia = dotted line, Kopu II and Louisiana = dashed line).
