indicated in the same publication that in Hydrangea
plant with blue sepals there was Al more than in the
pink ones. This agrees too with the results of this work.
Conclusion
Although micro-nutrient (Functional nutrient) aluminum
available for uptake by the plant has an effect on the
color of Hydrangea plant, the results of this work
proved that Al has an influence on some other
parameters.
Increasing the concentration of Al more than 50 mg/l
will affect the content of chlorophyll a, b, Carotenoids
and anthocyanin amount.
Many questions concerning plant response to Al can be
posed but very few answers can be given, so many
researches must be done to know more about Al and its
influences on Hydrangea.
