Abstract

Anatomical and morphological characteristics of Trichocereus candicans (Cactaceae) seedlings. The aim of this study was to examine the morpho-anatomical characteristics of Trichocereus candicans (Gillies ex Salm-Dyck) Britton & Rose seedlings, a columnar cacti species widely distributed in arid and semiarid regions of Argentina. The most significant changes in seedling morphology can be observed within the first 30 days from germination. Primary root is characterized by abundant radical hairs and a definite-growth pattern. Epidermis is uniseriate with wavy cells, parallelocytic stomata and mineral inclusions (druses). Xylem is composed by wide-band tracheids, with either helical or annular thickenings. Abnormal seedlings with three cotyledons were observed. This study provides basic knowledge of the species that may be useful for further taxonomic and ecological studies.
