  1. Values (mean ± standard deviation) followed by the same letter are not significantly different at α = 0.05 with the Bonferroni t-test. The pollen grains were collected from 10 flowers on five plants (two flowers per plant) and then mixed together for each cultivar. Approximately 2000 pollen grains were counted for each estimate. A, G, M and Q represent the lotus cultivars, ‘Aijiangnan’, ‘Guili’, ‘Molingqiuse’ and ‘Qinhuaiyanzhi’, respectively.
