森林树种构成一种还没有被人们驯化的重要资源。森林群体包括着广泛的未经选择的自然变异。本文中我们讨论了能促使树木具有某些特性和分析自然遗传变异的离体培养技术,讨论了诱导和分离新遗传变异的技术,还讨论了为创造适合人们需要的珍贵栽培品系的遗传可能性的新的联合。但是应该再次强调,在这些技术中现在还没有一个成为常规程序。在组织培养方法被有效的使用之前,要紧的是,同苗期可以测量的特性或在离体培养中能够选择的生化特性相关联的成龄树木所表现出的那些重要特性(依据产量、产品质量或管理要求)。
Forest trees form an important resource that has not yet been domesticated. Forest groups include a wide range of unselected natural variations. In this paper, we discuss in vitro culture techniques that promote trees with certain traits and analyze natural genetic variations, discuss techniques for inducing and isolating new genetic variations, and discuss the genetic possibilities for creating valuable cultivars that are tailored to people’s needs New union. However, it should be emphasized once again that none of these technologies are now routine. Prior to the efficient use of tissue culture methods, it is important that those important characteristics (as a function of yield, product) of the mature trees that are associated with measurable characteristics at seedling stage or with biochemical properties that can be selected in vitro, Quality or management requirements).
