Working day about the staquillado semileñoso of the castaño and cerezo (June 6, 2014)
The spread of chestnut clones is made from several decades by various methods –steam cutting and different farming techniques of in vitro culture- all of them totally valid under the terms and objectives.
In the ‘Centro de Investigación Forestal de Lourizán’ chestnut semi wody steam cutting is used since 1991. The technique is applicable to mass propagation of rootstock clones for wood with good aptitude to propagation.
The wild cherry semi woody steam cutting is being developed in the ‘Centro de Investigación Forestal de Lourizán’ for years with good results for the cloning of individuals for basic materials for the production of cherry wood.
In the process of steam cutting, it can be distinguished several stages: the selection and training of mother plants for cutting, the root cutting with the use of auxin, and control of environmental conditions that contribute to moisture and light necessary for the rooting process.
In general, the steam cutting is a system that needs more infrastructure than the layering and less that the in vitro culture. It presents some advantages such as ease of change of the clones for cultivate, or ease of health control of mother plants.
