| Abstract:
In the present paper information regarding the course of ontogeny in Papaver nudicaule L. have been collected. Observations concerning leaf number, axillary bud number and flower bud number were effected every 10 days on 40-day-old seedlings until flowering. During the biological cycle from sowing in August to transplantation in September, the plants, after producing 21–29 leaves (including primordia), transited into the reproductive phase. The first visible signs of floral induction on the main axis was an onset of elongation of the shoot apex. Contemporaneously 1–3 axillary buds developed at the axil of the more internal leaf primordia as soon as floral induction on the main axis was observed. They showed the same sympodial growth as the main axis. At the first flower anthesis the plant had 30–50 flower buds in different developmental stages. | |
