The mean proportion of seeds per fruit sired by self-pollen (mean ± s.e.) following simultaneous pollinations in the cataflexistylous morph (Cata-M) and anaflexistylous morph (Ana-M) of Alpinia blepharocalyx. Chi-square tests were used to compare observed values with the expected ratio of 1:1 if siring success of self- and outcross donors is equal. A significance level of P < 0·001 was found for all treatments except for mixed pollination in the morning for Cata-M (P = 0·0588).
