Knowledge about Slovenian cultivars of bearded iris (Iris barbata L.)

Na Laboratorijskem polju Biotehniške fakultete smo izvedli poskus z namenom, da pridobimo osnovne podatke o rasti in razvoju različnih slovenskih sort bradatih perunik, ter izvedli primerjavo z določenimi tujimi sortami. V poskus smo vključili 6 sort slovenskih perunik (\u27Mala Solfatara\u27, \u27Zlata Paleta\u27, \u27Zlati Ornat\u27, \u27Mala Pozlata\u27, \u27Majske Poljane\u27, \u27Majska Andromeda\u27) in 6 sort tujih perunik (\u27Old Black Magic\u27, \u27Parfume de France\u27, \u27Princesse Caroline de Monaco\u27, \u27Baltic Star\u27, \u27Born Beautiful\u27, \u27Eleanor\u27s Pride\u27). Sorte smo morfološko primerjali po širini in dolžini rozete rastline, višini cvetnega stebla, višini listne mase, številu cvetov na rastlino. Izmerili smo tudi barvo cvetov, beležili čas cvetenja in ocenjevali občutljivost za listno pegavost. Povprečna širina in dolžina rastlinske rozete rastlin slovenskih sort sta večji od rastlin tujih sort za 2,6 cm. Glede višine listne mase so rastline tujih sort povprečno merile 6,2 cm več od slovenskih sort. Največja povprečna dolžina cvetnega stebla rastlin tujih sort je bila večja od slovenskih sort za 28 cm. Spomladi najprej pričnejo cveteti nizke sorte bradatih perunik. V našem poskusu so pričele cveteti aprila rastline slovenskih sort \u27Mala Pozlata\u27 in \u27Mala Solfatara\u27. Visoke bradate perunike so začele cveteti meseca maja in kot prva sorta, ki je začela cveteti, je bila slovenska sorta \u27Majske Poljane\u27. Povprečno število cvetov na rastlino je bilo največje pri rastlinah slovenskih sort perunik. Za listno pegavost perunik so bile najbolj občutljive rastline tujih sort, najmanj okužena je bila listna masa sorte \u27Mala Solfatara\u27.In the Biotehnical faculty laboratory field, we performed an experiment in order to obtain basic data in the growth and development of bearded Slovene irises and also to compare them morphologically among themselves and also toward foreign cultivars. The experiment included 6 varieties of Slovenian irises (\u27Mala Solfatara\u27, \u27Zlata Paleta\u27, \u27Zlati Ornat\u27, \u27Mala Pozlata\u27, \u27Majske Poljane\u27, \u27Majska Andromeda\u27) and 6 varieties of foreign irises (\u27Old Black Magic\u27, \u27Parfume de France\u27, \u27Princesse Caroline de Monaco\u27, \u27Baltic Star\u27, \u27Born Beautiful\u27, \u27Eleanor\u27s Pride\u27). Among the varieties we morphologically compared them by width and length of the plant rosette, the height, the number of flowers per plant. We also measured flower colour, flowering time and assessed susceptibility to leaf spot. The average width and length of the plant rosette were 2,6 cm larger than foreign varieties. The height of the leaf mass was with 6,2 cm on average in foreign cultivars higher than Slovenian cultivars. The largest average length of the flower stalk of plants was measured by 28 cm foreign cultivars compared with Slovenian cultivars. Bearded irises begin to bloom in spring, holds true especially for lower varieties, but the Slovenian varieties \u27Mala Pozlata\u27 and \u27Mala Solfatara\u27 began to bloom in April. Tall bearded irises began to bloom in May and the first cultivar, which start to flower was the Slovenian cultivar \u27Majske Poljane\u27. The average number of flowers per plant had most plants of Slovenian cultivars of irises. Foreign cultivars were the most susceptible to leaf spot and the leaf infection rate of plants of \u27Mala Solfatara\u27 variety showed the lowest infection rate
