in Complete Fruit and Seed Production in the Self-Incompatible
Angiosperm in Brassica rapa

Abstract
Pollination was a process of transferring pollen grains from the male
anther of a flower to the female stigma for plant reproduction and was
an important mechanism in the life cycle of plants. This experiment
involved a life cycle of Brassica rapa which was a member of the mustard
or cabbage family. Brassica rapa was exceptional in its rapid
development from seed to seed within four weeks. Morphological aspects
and characterization of pollination was an important topic for
developing fruit and seed production in the life cycle of the plant. The
objective of this experiment was to assess the effects of
cross-pollination on fruit and seed production of Brassica rapa. The
major methods for this experiment required to use two Styrofoam quads as
a control and a cross-pollinated watered the two seeds in each cell for
three days of experiment and used honey bee for cross-pollination. The
rate of developed fruit and the mean number of seeds were higher on
cross-pollination than on self-pollination. Conversely, the average of
undeveloped fruit in cross-pollination was 9.677 and the average of
undeveloped fruit in self-pollination was 13.937. This result indicates
that the rate of undeveloped fruit was higher on self-pollination than
on cross-pollination. This study concluded that regulated hydration of
pollen for pollination and balanced hydration and dehydration cycle to
pollen grains are the key result of this experiment.
