Table 3.

Overview of results of stalk length measurement in the experiments listed in Table 1, each shown for “all grains”: all treated grains (upper line) and “germinated grains only”: only those grains which germinated during the 7 days of the experiment (lower line). Mean W30x: mean stalk length in the W30 group (in mm); mean G30x: mean stalk length in the G30x group; S.D.: standard deviations: “grains”: at grain level (i.e., S.D. of 500 values), “dishes”: at dish level (i.e., S.D. of 20 or 25 values). P: significance level of differences between groups at grain level and dish level.
