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

4.2.12 Stem diameter

Stem diameter was varying from 0,7 to 1,5 cm (Fig. 21). On average amounted the diameter of the stem 0,92-1,01 cm and was independent of the light treatment. Plants were most of the time of the growth period weak vegetative, respectively very vegetative.

4.2.13 Diameter of the uppermost flowering cluster

The diameter of the uppermost flowering cluster decreased from about 1,0 mm to about 0,7 mm during the growth period. No significant differences between the light treatments were measured.
