4.2.6 Open flowers / fruits per plant

The number of open flowers / fruits of the Sonata plant reached about 40 for the higher light intensity and about 30 for the lower light intensity before harvest started (Fig. 12). Thereafter, decreased this number naturally due to harvested fruits. The decrease seems to be more pronounced at the higher light intensity. The number of open flowers / fruits of Delizzimo was about 20. The higher light intensity had a slightly higher number. After that decreased also here the number, but is supposed to increase again later (Fig. 12).

4.3 Yield

4.3.1 Total yield of strawberries

The yield of strawberries included all harvested red fruits during the growth period. The fruits were classified in extra-class (> 25 mm), 1. class (18 mm) and not marketable fruits (too little fruits (< 18 mm), misshaped fruits, moldy fruits and green fruits at the end of the harvest period).

Cumulative total yield of strawberries ranged between 0,21-0,39 g/plant (Fig. 13). A higher light intensity increased tendentially, respectively significantly total yield. The total yield of Sonata was at the higher light intentensity higher compared to Delizzimo.
