Disturbances in the development of the female gametophyte in fully fertile tomatoes (Lycopersicon esculentum L. Mill) and those showing a tendency to parthenocarpy

Barbara Gabara, Bogusław Kubicki

Abstract


It was found that part of the ovules in two lines of Lycopersicon esculentum: Kholodostoykye (Kh, fertile) and A33 (with a tendency to parthenocarpy) show disturbances in the development of the embryo sac. These irregularities can be seen in four phases: pre-meiotic, post-meiotic (tetrad), nucleate and cellular. The majority of irregularities were observed in the cellular stage of embryo sac development. The total number of ovules with disturbed female gametophyte was higher in the A33 (32.6%) than in the Kh line (23.5%).
