摘要:: 以西藏色季拉山不同海拔梯度间3种花色杂色钟报春为试材，采用野外采样的方法，研究了不同海拔对花特征和繁殖分配的影响，以期探讨不同花色杂色钟报春繁殖策略对海拔的响应。结果表明：随着海拔的升高，紫色居群的茎分配随着海拔的升高显著地降低。3种花色杂色钟报春的叶分配呈增加趋势，花分配呈减少趋势，但差异并不显著。5个花特征参数（总花数、单花面积、单花质量、花展示面积、繁殖投入）随着海拔的升高在3种花色中变化趋势不同，但表现均不显著。繁殖分配随着海拔的升高而呈不显著的减少趋势。3种花色的总花数、繁殖投入和白色类型的花展示面积与个体大小呈显著正相关。海拔和个体大小共同对总花数（白色类型）和繁殖投入（紫色类型）产生影响，而对其它个体大小依赖的繁殖组分没有显著影响；繁殖分配与个体大小呈负相关，但在一些海拔梯度上不显著。总之，海拔并不是影响杂色钟报春花特征和繁殖分配的唯一因子。不同花色的繁殖策略并不完全相同，但差异不明显。

Abstract:: In order to investigate the response of reproductive strategy of Primula alpicola to altitude,flower traits and reproductive allocation of three colors in P. alpicola at different altitudes on Sejila mountains were examined through field sampling.The results showed that,as altitude increased,stems distribution of purple flower populations decreased significantly,leaves distribution and flowers distribution of three colors were respectively in the trend of increasing and decreasing but difference were not significant.The five flower traits included total flower number,single flower area,single flower weight,flora display area,reproductive investment had different change tendencies,all of which were not significant.Reproductive allocation did not decrease obviously with altitude rising.There was no obvious correlation between altitude and reproductive allocation.The correlations between reproductive traits and individual size were various at different altitudes.Total flower number,reproductive investment and flora display area of white flower populations were positively correlated with individual size significantly.Both altitude and individual size affected total flower number of white flower populations and reproductive investment of purple flower populations,but had no important influence on the other size-dependent reproductive traits of different colors.There were no consistent correlation models between individual size and single flower area,single flower weight separately at varying altitudes.Reproductive allocation had negative relationships which were no significant on some altitudes with individual size.In short,the results suggested that altitude didn′t significantly influence flower traits and reproductive allocation of different colors of P.alpicola.Altitude could not fully explain the change of resource allocation strategy of P.alpicola.Reproductive strategies of different colors were not exactly the same with slight differences.
