Abstract

The floral biology, pollen/ovule ratio, pollen viability, flower visitors, pollination process and fruit set of Commelina communis were observed, measured and recorded in Kunyu Mountain, Shandong Province. The main results were as follows: The flowers of C. communis came into blossom at 3:00~5:00am, full-blossom before 6:00 and petal-shut at 12:00~13:00. The life-span of single flower of C. communis was about nine hours. In the four hours after flowering, the pollen viability was higher than 92%; six hours later, no pollen viability was detected. The P/O was 321±13. The results showed that C. communis was facultative autogamous. C. communis was pollinated by at least 4 species, of which syrphid fly was the main flower visitor. Fruit set of the completely netted flowers accounted for 92.7% of that under natural conditions. These indicated that self-pollination predominated in C. communis, xenogamy just played an auxiliary role in the breeding system.
