4.2.5 Length of leaves

Length of leaves during the experiment remained at 36-48 cm (Fig. 13). The light treatment had no influence on the length of the leaves.

Letters indicate significant differences (HSD, p ≤ 0,05).

4.2.6 Number of clusters

The number of clusters increased with approximately one additional cluster per week. The treatment “Hybrid high” had a significantly lower amount of clusters compared to “HPS”, whereas no differences in the number of clusters were observed for “HPS” and “Hybrid” as well as for “Hybrid” and “Hybrid high” (Fig. 14).

4.2.7 Length of clusters to top

The length from the uppermost flowering cluster to the top of the plant amounted on average 18-20 cm with no significant differences between light treatments (Fig. 15).
