FLORAL-BIOLOGICAL CHARACTERISTICS AND FRUIT DEVELOPMENT OF FENNEL

On the basis of examinations the speed of flower development of two population of fennel (Foeniculum vulgare var. subsp. capillaceum var. vulgare ’Soroksári’ and selected population of genebank origin ’F86’) depends on species and regulated by range of umbels, mainly.
The 6^th and 7^th phases of flowering, which are the most time consuming periods, need 7 or 8 days in case of the 1^st range umbels, while only 5 or 6 days in 3^rd range umbels.
It was justified as well, that the germination power of seeds depends on maturity stage in which they were collected.
Green seeds can be characterised by 40-60 % of germination, while this value increases up over 70 % if waxy and ripen seeds are tested.
In harmony with literature data the essential oil content of fruits is the highest in „green seed” stage (5.83 ml/100g and 5.68 ml/100g in case of ’F86’ and c.v. ’Soroksári’, respectively).
