Comparable with the result reported by [8], the development of leaf chlorophyll
content was specifi c for every variety. Among inoculated plants, no signifi cant differ-
ences at all three observations could be measured in Aveline (Figure 10.5, clear). In
contrast, SPAD values of inoculated Augusta and Sibniik315 increased signifi cantly
with time (Figures 10.6-10.7: BBCH 21 to 70), but no signifi cant differences occurred
without treatment (Figures 10.6-10.7 gray).
The highest Sibniik315 SPAD value was noticed at the second measurement
(BBCH 70, inoculated), which decreased slightly in BBCH 75 (Figure 10.7, clear) as
well as in the control. This may imply a better adaption of the Siberian variety to the
local climate condition (short vegetation period) than the German breeding because
relocation effects from vegetative to generative plant organs occurred earlier. Never-
theless, inoculated Sibniik315 showed the highest number of nodules; SPAD measure-
ments were less distinctive (not signifi cant) and higher compared to control.
