Eid G.M., Albatal N and Haddad S., 2015, Effect of Aluminum Sulfate on the Chlorophyll a, Chlorophyll b, Carotenoids and Anthocyanin Content in Some Cultivars of Hydrangea (Hydrangea macrophylla), International Journal of Horticulture, 2015, Vol.5, No.9 1-8 (doi: 10.5376/ijh.2015.05.0009)

The experiment was conducted in Hama governorate (Bammraa village) during the spring and summer seasons 2011- 2012 to study the effect of Aluminum on the content of chlorophyll a, b and Carotenoids in leaves and also the content of anthocyanin in sepals. Aluminum in leaves and flowers was measured to estimate its amount in all treatments.

Aluminum sulfate was supplied in different concentrations (control, 50 mg/l, 100 mg/l, 150 mg/l) to two cultivars of Hydrangea macrophylla. Nikko Blue (a cultivar with blue color flower), Pia (a cultivar with deep pink color flower).These plants were two years old and planted in pots. It was used four treatments, there was three replications in every treatment and in every replication there was six plants. The media was peat moss and perlite (2:1).

Results indicated that increasing Aluminum sulfate more than 50 mg/l caused a decrease in the content of chlorophyll a, b and the content of Carotenoids in leaves, Also anthocyanin was best in the concentration 50 mg/l in the two cultivars with significant differences.

In addition, the results showed that the cultivar (Nikko blue) was more responsive in some studied indicators. Also it was proved that the amount of Aluminum in leaves was more than in the flowers of the two cultivar .
