Abstract: Floral traits, as one of the most diverse and complex collections of traits in life history stages of plants, perform ecological functions such as attraction, defence and resistance to achieve successful reproduction. Flower colour has lagged behind other traits in the study of floral traits, but flower color and its relationship with other floral traits play an important role in attracting pollinators and reproducing offspring in plants. In this study, we analyzed the diversity and correlation of five types of floral traits, including flower color, in 20 species of Apocynaceae, aiming to gain a deep understanding of the diversity of floral traits and their ecological strategies. The results showed that there was a wide diversity of floral traits in Apocynaceae, with significant differences between some floral traits of plants with different flower colors. In addition, we found different degrees of correlation between different floral traits in Apocynaceae, suggesting that plants are able to adopt appropriate ecological strategies through their own needs.

Key words: Apocynaceae, floral traits, flower colour, diversity, ecological strategy

摘要: 花性状作为植物生活史中最为多样和复杂的性状集合之一,在植物的生长发育过程中通过发挥吸引传粉者、防御啃食者和抵抗逆境等生态功能实现成功繁殖的目的。在花性状的相关研究中,花颜色研究相对其他性状较为滞后,但花颜色及其与其他花性状之间的关系在植物吸引传粉者以及繁衍后代等方面都发挥着重要作用。本研究对20种夹竹桃科植物的花颜色等5类花性状进行多样性和相关性分析,旨在更加深入地了解夹竹桃科植物花性状的多样性及其生态策略。结果表明,夹竹桃科植物的花性状存在广泛的多样性,不同花色植物的一些花性状间存在显著差异。此外,夹竹桃科植物不同花性状之间存在不同程度的相关关系,表明植物能够通过自身需要采取合适的生态策略。
