4.2.11 Number of open flowers

On the uppermost cluster was the number of open flowers counted. The number of open clusters fluctuated during the growth period at around four open flowers/cluster. On average were no significant differences between the light treatments observed (Fig. 20).

4.2.12 Stem diameter

Stem diameter was varying from 0,6 to 1,4 cm (Fig. 21). On average amounted the diameter of the stem 0,97-1,07 cm and was independent of the light treatment. Plants were most of the time of the growth period weak vegetativ.
