| Abstract:
During six successive cultures (1993-1999) of short day strawberries (Fragaria x ananassa Duch. 'Elsanta'), grown on peat bags, the effect of the addition of silicon (Si as K2SiO3) to the nutrient solution was examined. Unsufficient colouring was related to the concentration of silicon applied by the nutrient solution. Preliminary tests showed a significant lower content of the two major anthocyanins, pelargonidin 3-glucoside and cyanidin 3-glucoside in albino berries. For pelargonidin 3-succinylglucoside no significant differences were found. Mineral analysis of albinofruits showed a significant higher nitrogen and potassium content, and in some samples a lower calcium content. However, the potassium-calcium ratio in the nutrient solution did not clearly influence the percentage of albinofruits. | |
