CLONAL FORESTRY OF Piptocarpha angustifolia: SURVIVAL AND GROWTH VIGOR IN FIELD CONDITIONS [PDF]
CERNE, 2017 ABSTRACT Piptocarpha angustifolia is a potential native species for Brazilian forestry. However, a lot of challenges and technical constraints persist, hindering its expansion as a species for forest plantations, among them, the lack of evaluation of their survival and growth in field conditions.

ARAUCARIA CLONAL FORESTRY: TYPES OF CUTTINGS AND MOTHER TREE SEX IN FIELD SURVIVAL AND GROWTH [PDF]
CERNE, 2016 ABSTRACT Araucaria angustifolia (Bert.) O Kuntze (Paraná pine or Araucaria) is a potential forestry native species for Brazilian silviculture. However, a number of challenges and technical restraints persist, hindering its silvicultural expansion, among which are the lack of cloning technologies of superior genetic materials and their assessment under ...

Clonal Propagation Index for cutting production in forestry
Revista Forestal Mesoamericana KurúWith the development of clonal production systems in forestry, there is a need for efficient indicators to determine the production capacity of the system. The Clonal Propagation Productivity Index (CPI) is recommended to determine the effect of possible technical improvement on the production capacity.
