The effect of term of planting and size of bulbs on the yield of Allium moly bulbs was examined. Bulbs of circumference of 5–6 and 6–7 cm were planted in three terms: 29.09; 09.10 and 19.10. It was stated that term of planting as well as size of bulbs have significant effect on number and weight of bulbs in the total yield and in the yield of the biggest bulbs (over 6 cm circumference). The optimal term of planting was 29.09, when the best results were obtained. Bulbs of circumference of 5–6 cm gave significantly bigger yield than those of 6–7 cm circumference in respect to quantity and weight.
The paper presents the results of the study on seed morphology of eight following Allium species: A. pyrenaicum Costa & Vayr., A. rotundum L., A. sphaerocephalon L., A. vineale L., A. moly L., A. karataviense Regel, A. fistulosum L. and A. nutans L. The study confirmed the substantial diversity in testa characters, especially curvature and relief of anticlinal walls as well as microsculpture of outer periclinal walls. The occurrence of raised anticlinal walls – an unusually rare feature in Allium seeds, previously observed only in a few species, was found in A. karataviense. It was also found that the testa type in A. pyrenaicum did not match the typical character combination, described before for subg. Allium sect. Allium.
Doświadczenie wykonane w sezonie 2000/2001 i 2001/2002 miało na celu opracowanie charakterystyki fenologicznej i morfologicznej 12 gatunków i odmian czosnków: błękitnego (A. caeruleum), czarnego (A. nigrum), główkowatego (A. sphaerocephalon), karatawskiego (A. karataviense), kazachstańskiego (A. oreophilum), Krzysztofa (A. christophii), neapolitański (A. neapolitanum) olbrzymiego (A. giganteum), Rosenbacha (A. rosenbachianum) złocistego (A. moly), sztyletowatego bułgarskiego (A. siculum ssp. bulgaricum) i Allium ‘Gladiator’. Określono czas trwania pojawów fenologicznych: ukazanie się roślin nad powierzchnią ziemi, ukazanie się pąków kwiatostanowych, rozpoczęcie i zakończenie kwitnienia, zasychanie liści. Oceniono cechy morfologiczne: długość szypuły kwiatostanowej, liczbę kwiatów w kwiatostanie, długość liści, liczbę liści, barwę kwiatów i liści oraz współczynnik rozmnażania. Na ich podstawie określono możliwość zastosowania roślin i wykorzystania w terenach zieleni.
