Host tree bark traits and development of reintroduced Cattleya intermedia (Orchidaceae) plants in Southern Brazil

Abstract

Abstract The traits of the bark of host trees can influence the distribution and development of epiphytes. Bark samples were suspended in 10 and 20 mL of distilled water for 1, 4 and 24 h, to evaluate pH determination methods. Bark samples of Myrcia brasiliensis, M. glabra and Myrsine coriacea, three host trees of Cattleya intermedia had bark samples collected from the trunk and the crown, for the evaluation of the pH, water retention capacity and thickness. Shoot height (cm) and number of roots of C. intermed…
