Role of endogenous growth regulators in vernalization of seeds of radish (Raphanus sativus L.)
In embryos and cotyledons of seeds of the radish cv. `Tetra Iłówiecka' (which needs 20 days of vernalization) and cv. 'Saxa' (which flowers without vernalization) germinating at a vernalizing temperature of 5°C, the levels of auxins, gibberellins, cytokinins and the aibscisic acid-lik...

| description | In embryos and cotyledons of seeds of the radish cv. `Tetra Iłówiecka' (which needs 20 days of vernalization) and cv. 'Saxa' (which flowers without vernalization) germinating at a vernalizing temperature of 5°C, the levels of auxins, gibberellins, cytokinins and the aibscisic acid-like inhibitor were determined, The analyses were performed after 5, 10, 15, 20, 25 and 30 days of chilling. The levels of growth regulators were also determined in embryos and cotyledons of seeds germinated at 260C when in the same growth stage as the material taken from chilled seeds. Cold treatment significantly affected the level of all endogenous growth regulators in embryos and cotyledons of both varieties. However, changes in the levels of these substances were not directly connected with the vernalization process. It was found that the vernalization of seeds of 'the radish cv. `Tetra Iłówiecka' increased the level of GAs in leaves, this did not, however, coincide with flower initiation. It is concluded that the role of GAs in flowering of the studied plants is connected rather with photoinduction than with vernalization. |
