Tree Breeding and Seed Management Terminology
1 Scope
This document defines common terms used in forest tree breeding and tree seed management:
This document is applicable to the fields of production, scientific research, teaching and management of the forest seed industry:
2 Normative references
This document has no normative references:
3 Basic terms
3:1
tree species
There are significant differences in morphological characteristics, and there are reproductively isolated woody plants:
Note: The most basic unit in the classification system of woody plants is the basic biological basis for a species to be established in classification:
3:2
The area occupied by all individuals of each tree species in nature:
Note: According to the distribution area, it can be divided into continuous distribution area and discontinuous distribution area; according to the origin, it can be divided into natural distribution area and cultivated distribution area; according to distribution space, it can be divided into horizontal distribution area
area and vertical distribution area:
3:3
A state in which the distribution of a species or subspecies of taxa is connected in one piece without discontinuity:
3:4
The distribution area of a species or a taxonomic unit below a species is in a discontinuous state:
3:5
forest tree seed
The general term for the sexual reproductive organs of forest trees and the sowing materials in forestry production:
Note: Including real seeds (such as pines, birches), fruits (such as samara, nuts, etc:), parts of fruits (such as walnuts, neem, etc:), parts of seeds (such as
Ginkgo, Magnolia) and seeds formed by apomixis (such as citrus, etc:):
3:6
Seed origin seedsource
The original collection location of the seeds:
3:7
seed zone seedzone
In the distribution area of tree species, the ecological conditions and genetic characteristics of forest trees are basically similar to the geographical unit:
Note: The basic unit of species is used:
