(5) Research on forestry has shown that, if forests are to be of increased value including the aspects of stability, adaptation, resistance, productivity and diversity, it is necessary to use reproductive material which is genetically and phenotypically suited to the site and of high quality; forestry seeds should meet, where appropriate, certain external quality standards;
(5) metsandusalased uuringud on näidanud, et metsade väärtuse, sealhulgas nende stabiilsuse, kohandumise, vastupidavuse, tootlikkuse ja mitmekesisuse tõstmiseks tuleks kasutada paljundusmaterjali, mis on geneetiliselt ja fenotüübilt kasvukohale sobivad ning kõrge kvaliteediga; metsanduse seemned peaksid vajaduse korral vastama teatavatele välistele kvaliteedistandarditele;
