Vegetation period of genetic resources of flax (Linum usitatissimum L.)

Abstract

Institute of Natural Fibres and Medicinal Plants (INF&MP) is involved in gathering and evaluation of genetic resources of flax (Linum usitatissimum L.), hemp (Cannabis sativa L.) and medicinal plants, because Poland has signed the Convention on Biological Diversity. Field trials were carried out in 1990–2001 in the Experimental Station in Wojciechów located in Opolskie region. The research material was accessions of genetic resources from the collection of flax, stored at the Institute of Plant Breeding and Acclimatization Institute in Radzików near Warsaw.
