Phylgreen

Norway maple (Acer platanoides 'Royal Red') in full soil  treated monthly with Phylgreen resulted after 3 years in an increase in plant height of 19,71% and an increase in stem diameter of  14,0% compared to the untreated control. The number of dead trees increased with 20% and the number of failed graftings decreased with 18,2% compared to the control. There was no effect observed on the amount of chlorophyll, flavonols, anthocyans and the nitrogen balance index (indicative for stress responses).
