Agrobiological characteristics of rare onion A. fistulosum L, A. nutans L. and A. schoenoprasum L.

Of the numerous vegetable species, the species from the genus Allium have a particular significance. In the frame of our study, A. fistulosum L. (winter onion), A. schoenoprasum L. (chives) and A. nutans L, botanically perennial species, form a pseudobulb without a dormant stage. These species sprout like onions, for 30 days. A. schoenoprasum L. and A. fistulosum L. form in the first year 3-4 plants in tillers. A. fistulosum L. is the highest, being 49 cm long, A. nutans L.(5) has the largest number of leaves and A. fistulosum L., sown in autumn, has the largest mass (about 21 g). High contents of vitamin C occur in the leaves, especially with the A. nutans L, over 20% of dry matter contents occur in the pseudobulb, phytocide and medicinal characteristics, together with decorative components make full value of these three Alliums
