Effect of altitude on reproductive ingredient and sex allocation of different colors of Anemone obtusiloba in populations

In this study, we aimed to explore the effect of altitude on reproductive ingredient and sex allocation different colors Anemone obtusiloba in populations. The variations three four altitudinal gradients at eastern Qinghai Tibetan Plateau were examined. Our results showed that with increased altitude, gynoecium/flower, androceium/flower gynoecium/individual increased, but androceium/individual, gynoecium number/flower, androceium number/ individual number/individual flower color decreased. Besides, male ♂/♀ also decreased, which female-biased allocation. Furthermore, gradients, size same was positively correlated ingredient, had a direct impact size-dependent ingredient. However, there not certain correlations between allocation, obtusiloba. Moreover, investment androceium, investment. conclusion, significant Different all female function altitude. difference influence mechanism distribution resource.
