Overcoming dormancy and establishment of normal and abnormal seedlings for seedling production of Ochroma pyramidale (Cav. ex Lam.) Urb
Ochroma pyramidale (Cav. ex Lam.) Urb has great economic importance due to fast growth have, tegument dormancy, and variation in the germination process, where dormancy overcoming is fundamental in the study of seedlings. The aim of this study was to describe the external morphology of early stage d...
