在甘蓝型油菜生殖生长的不同阶段,将~(14)C从主花序和顶叶引入植株内。标记后立即测定生殖器官及主花序不同部位的花梗和茎内的放射性活度。24小时后收获整个植株,对其不同部位进行放射性测定。结果表明,中部的花器和上部的主花序固定的~(14)C高于基部。在开

In different stages of reproductive growth of Brassica napus, ~ (14) C was introduced into the plant from the main inflorescence and the parietal lobe. Immediately after labeling, the radioactivity of pedicels and stems in different parts of the reproductive organs and main inflorescences was measured. The whole plant was harvested 24 hours later and radioactively assayed at different sites. The results showed that the central floret and the upper main inflorescence fixed 14 C higher than the base. In the open
