研究了染色体加倍对3个不同细胞型的杜氏牡丹品种（McAllesteri、Pink Beauty和Blue Beauty）的叶片数量、花产量、生物量以及对土壤水分梯度的响应宽度的影响。染色体数目的增加导致生长速度减慢。叶和植物寿命，开花晚，同步少，并产生较少的花的趋势，增加。所有四倍体都丧失了在潮湿环境中繁殖的能力。其他因素，如程度的反应宽度，重叠和活力增加，由于染色体数目增加的基因型依赖。多倍体水平对繁殖前死亡的数量没有影响。
The effects of chromosome doubling upon leaf demography, flower production, biomass and response breadth on a soil moisture gradient of 3 cultivars [McAllesteri, Pink Beauty and Blue Beauty] of P. drummondii, each cultivar being represented by 2 cytotypes, were investigated. Increased chromosome number produced slower growth rates. Leaf and plant longevity, a tendency to flower later and less synchronously, and produce fewer flowers, increased. The loss of the ability to reproduce in hydric environments occurred in all tetraploids. Other factors such as degree of response breadth, overlap and increased vigor due to increased chromosome number were genotype-dependent. Level of polyploidy had no effect upon the number of pre-reproductive deaths.
