单词	self-fertile
释义	self-fertile /sɛlfˈfəːtʌɪl / adjective Botany (Of a plant) capable of self-fertilization.For example, it has a small diploid genome, self-fertile flowers, and a short generation time.... Despite the fact that only a small number of selfed fruits were produced on self-fertile plants in our study, variation in self-fertility was evident. There was variability among self-fertile plants in their propensity to mature selfed fruits, but, on the whole, selfed fruit-set was very low compared to outcrossed fruit-set. Derivatives self-fertility noun ... Despite the costs of inbreeding depression, self-fertility has evolved repeatedly in diverse taxa of flowering plants. Plants also show great ranges in self-fertility from obligate outcrossing to complete selfing to apomixis (uniparental). Perhaps the mutation that results in self-fertility arrived as a seed dispersed into the eastern half of the population, and not enough time has passed for it to spread or be lost.
