Analysis of the structure, prinsiples of classification and appreciation of the collection funds of cultivated plants

Abstract

The collection funds of cultivated plant have been systematized as to time and quality-quantity parameters. Three types of collections as to time of their existence were distinguished: transitory (provisional), onoprolonged (change-prolonged), increasoconstant (progressing-permanent). The criteria for collections differentiation by quality-quantity structure have been determined and it was proposed to establish five base standards: fragmentary, semi-complete, complete, absolute, maximum collections.
