Stem‐cutting anatomy and biochemical responses associated with competence for adventitious root diferentiation in Acca sellowiana (Myrtaceae)

Successful development of adventitious roots (AR) in cuttings imposes an important limitation to the propaga- tion of woody plants and in some species, the ability to form AR is strongly afected by genotype. However, we lack an understanding of the diferences among genotypes underlying such dife...
