AbstractTwo opposite views exist regarding sexual versus asexual reproductive performance of Polygonum viviparum. One suggests that increasing altitude favors flower production, while the other suggests that increasing altitude increases bulbil production. In this study, we present an investigation of the reproductive performance of 13 populations of P. viviparum on the Qinghai-Tibet Plateau (QTP). Our results show that, with increasing altitude, the height of inflorescence and total number of flowers and bulbils decrease significantly, but there is no significant effect on bulbil and flower number. In addition, there is a weak correlation between the proportion of flowers per population and altitude in our study sites due to the exception population 12, which is in a disturbed habitat. We conclude that more resources might be allocated to flowers in populations at higher altitudes, indicating the importance of sexual reproduction over asexual reproduction in alpine plants of QTP.
