Appearance of phenotypic plasticity of leaves in psammophyte Corynephorus canescens during flooding

The results of the study leaf structure in psammophyte Corynephorus canescens, which grew under controlled conditions and flooding using methods light microscopy, scanning electron laser confocal are presented. This revealed common distinctive signs morphological anatomical parameters C. canescens leaves phase vegetative growth. Among features were shape size laminas, hypostomatic type leaf, isolateral parenchyma, thick-walled epidermis, bilayered hypodermis. destruction cells photosynthetic change their with formation protuberances at cells’ poles, almost doubling area aerenchyma conditions. Scanning microscopy showed similarity ultrastructure density trichomes on adaxial surface, excepting cuticular wax structures epidermal surface flooded plants. subcellular localization silicon inclusions was studied for first time. presence amorphous small crystalline periclinal walls main established. An increase relative content along leaves’ epidermis after revealed. It assumed that phenotypic plasticity is realized through increasing trichomes. Such helps to optimize both oxygen balance plants water plants, thus species’ resistance prolonged flooding.
