ABSTRACT
The research was carried out over the years 2000-2002, on 20 tulip cultivars grown in two commercial tulip plantations located in the South-Eastern Poland. The healthiness of plants was examined at the beginning and the end of flowering, and after digging and storage time.
The disease index values of above-ground plant parts ranged from 10.4 to 30.2. The most infected cultivars were ‘Christmas Surprise’, ‘Apricot Beauty’ and ‘Genera³ Eisenhower’.
From the above-ground plant parts most frequently isolated species were Alternaria alternata. Species Botrytis tulipae occurred more frequently on the foliar parts of tulips cultivated in Wojszyn at the beginning of flowering.
The mean disease index values of bulbs ranged from 2.5 to 10.4. The most infected cultivars were ‘Apricot Beauty’, ‘Oriental Splendour’ and ‘Czerwony Kapturek’.
From the diseased bulbs of tulips after digging, as well as after storage, the greatest number of fungi isolates belonging to the species P. verrucosum var. cyclopium were obtained.
Key words: tulip, cultivars, fungi, isolation, foliar parts, bulbs, disease index.
