Effect of Fylloton Application on Photosynthetic Activity of Moldavian Dragonhead (Dracocephalum moldavica L.)

The field experiment was carried out in 2014 in Perespa, Poland to examine the impact of biostimulant Fylloton on the photosynthetic activity of Moldavian dragonhead cv ‘Alba’. Moldavian dragonhead seeds were sown in April at a depth of 1-1.5 cm, with the spacing 45 x 20 cm. During the growing season, Fylloton was foliar-applied at a dose 2 l/ha (0.7%) and 3 l/ha (1%) by single spraying or double spraying of plants. One week after application of biostimulator, the photosynthetic activity of plants was measured. Use of Fylloton had a positive impact on the efficiency of photosynthetic apparatus and chlorophyll content in the leaves of Moldavian dragonhead plants. Fylloton is environmentally friendly preparation and helps to improve the efficiency of photosynthetic apparatus. It should therefore be recommended for use in sustainable agriculture.
