BEHAVIOUR OF SOME IRIS CHRYSOGRAPHES GENOTYPES IN AGROBOTANICAL GARDEN USAMV CLUJ-NAPOCA

Abstract

Diversification of the ornamental plants assortment with new species and genotypes that exhibit exceptional decorative characteristics has been a continuous preoccupation for specialists in Romania. The testing of these new species and genotypes in the conditions of our country as well as settling technical cultivation aspects are necessary prior to utilizing them for green spaces. Iris chrysographes is a species native to Asia that is highly appreciated for the dark violet color of the flowers. At the present time in various collections, for this species there are available hybrids, cultivated forms that often have been bred for darker shades and wild genotypes obtained from seeds collected in the native regions of the species. Cultivars of this species have been introduced and tested in the pedo-climatic conditions of Agrobotanical Garden of USAMV Cluj-Napoca. After two year observation period, has been concluded that accessions belonging to cultivated forms (Iris chrysographes “Black Form”) present the best adaptability followed by the hybrid Iris chrysographes x forrestii.
