Abstract
Worldwide exchange and trade of propagating material of ornamental crops is a still rapidly growing economic activity.
New varieties are developed in all major production regions and can be of value to all growers worldwide.
To start professional propagation and production, the highest quality and plant health is required.
Users of plant material must be sure that they receive this material pathogen-free.
New varieties are developed in all major production regions and can be of value to all growers worldwide.
To start professional propagation and production, the highest quality and plant health is required.
Users of plant material must be sure that they receive this material pathogen-free.
In line with existing systems the author proposes to distinguish generally three classes of certified material: prebasis (nuclear stock), basis (propagation stock) and certified stock material.
It is up to virologists, mycologists etc. to draw up, in consultation with growers and propagators, standards and maximum allowed tolerances for pathogens.
Examples will be shown of certification systems of Dendranthema, Dianthus, Pelargonium and Petunia.
