    Abstract

    [Truncated] Ovules of the seeded diploid Musa acuminata (AA) and edible triploids (AAA) from the same cytogenetic group, plus edible triploids of the M. balbisiana cytogenetic group (AAB, ABB), were studied to determine their growth and development before and past anthesis. Of particular interest was the development of the embryo sac and whether the growth of reproductive tissues in the parthenocarpic fruit (edible triploids) differed from the fertile seeded fruit (diploids).Ovules were collected from 18 cultivars and species growing in subtropical northern New South Wales (Lat. 29o S) and the Mediterranean region of Perth, Western Australia (Lat. 32o S). Ensete sp. was available from the Perth Zoological Gardens. Ovules were examined histologically using light microscopy. Changes in size and shape were studied by evaluating a median sectional plant through the ovule. This ignores changes in size and shape that may take place in a third dimension. Within these limitations, the changes in ovule size and shape were quantified.
