Ovule maturity in relation to blossom age of a diploid clone of Solanum tuberosum
Keyword(s):
Numerous ovules from preanthesis and postanthesis gynoecia of a diploid clone of Solanum tuberosum L. were examined with the light microscope. In prefertilization female gametophytes, the formation of a secondary nucleus in the central cell in conjunction with the conspicuous vacuolation of the egg apparatus was identified as a consistent criterion for determining whether or not ovules were mature. There is a gradual increase in the percentage of mature, nonabortive ovules beginning on the day of anthesis and reaching a maximum 3 days later. In terms of pollination biology, mature ovules are available for pollen tube penetration over an extended period of several days.
