Abstract

The onset and duration of stigma receptivity in K. pomiferawas evaluated by observing stigma peroxidase, activity, pollen-tube growth and seed set, following controlled pollination of flowers of different ages. Peroxidase, activity was negligible from 1 day before to 4 days after anthesis, increasing to a peak of 65% at Day 13. The, percentage of pistils bearing germinated pollen and ovaries exhibiting pollen-tube entry increased when pollen was, applied to the stigma from the day before anthesis, to a maximum at Days 6 and 7 after anthesis, respectively, followed by a decline by Day 9. Under greenhouse conditions the optimum pollination period, measured as the level, of set seed after pollination, ranged from 2 to 11 days after anthesis. The knowledge of this aspect of the species, reproductive biology is of considerable value in controlled pollinations for its improvement as a new crop.
