Effect of a biogenic silica and green-teaflavonoids-based mechanocomposite on Fragaria × ananassa Duch. leaf anatomy in in vitro conditions

For the first time light and scanning electron microscopy have been to reveal changes in the anatomical structure of leaf blades of Fragaria × ananassa Duch. regenerants cultivated in nutrient media supplemented with biogenic silica and green-tea-flavonoids-based mechanocomposite. An increase in the density of stomata per unit area of the leaf, size of the stomatal gaps, thickness of the epidermis and mesophyll have been noted. The revealed changes in the leaf blade structure under mechanocomposite treatment contribute to the further successful acclimatization of regenerants to ex vitro conditions.
