Noni (Morinda citrifolia L.) is a medicinal plant recognized for its numerous therapeutic properties and its growing economic importance in several tropical regions around the world. Despite its potential, its cultivation remains limited by the seed coat dormancy of its seeds, resulting in slow and irregular germination. This book presents an experimental study conducted in a nursery, focusing on the influence of substrates and pretreatments on the germination of noni seeds.Using a rigorous scientific approach, the author analyzes the effects of various treatments-including scarification, maceration, and hot water-as well as two types of growing media. The results highlight the optimal conditions for breaking dormancy and improving germination parameters.This book is a valuable resource for students, researchers, nursery operators, agronomists, and agricultural development professionals interested in tropical medicinal plants and the domestication of economically valuable species.
