... known that the micropropagation of material from the crown of mature trees still remains very difficult. In a previous paper, we reported for five chestnut clones the morphogenetic capacity ... 1991). Therefore, the degree of reinvigoration depends on both the treatment being used and the characteristic being evaluated, sup- porting the...
