| ABSTRACT The velamen, a root structure of some epiphytic species for water uptake, usually is stratified epidermis consisting of dead cells. In general, its cell walls exhibit variation during development, including in thickness and amount and type of impregnated substances. These changes result in diverse physical and chemical properties that can serve in water and nutrient uptake, as well as in mechanical support and protection. On this basis, the main objective of the current study was to describe the composition of the cell walls of the velamen during the development of the roots of four species of Cattleya. Anatomical, histochemical and immunocytochemical analyses were performed with samples (n=3 individuals per species) of meristematic, developing,... |
