一个分离的U.莴苣属在合成培养基和富集海水中进行无菌培养。建立了单倍体克隆，并在两种培养基中经过几代。植物具有distromatic，部分distromatic或完全管状叶片的横截面，和个人完全distromatic在一个地区的叶片和管状的另一个，从同一个蜂群人口发展。断面积形态发生变化。任何这些形态类型的蜂群的后代表现出类似的形态变异的混合物，表明叶片和基部面积的表型表达的非突变变异。一种机制，这种变化可能会发生突变进行了讨论。
An isolate of U. lactuca L. was brought into axenic culture in defined synthetic medium and enriched seawater. Haploid clones were established and followed through several generations in both media. Plants possessing distromatic, partially distromatic or completely tubular blades in cross sections, and individuals that were completely distromatic in 1 area of the blade and tubular in another, developed from the same swarmer population. Variations in basal area morphology occurred. Progeny from swarmers of any of these morphological types showed a similar mixture of morphological variation, indicating non-mutational variability in phenotypic expression of the blade and basal areas. A mechanism by which such variation may occur without mutation is discussed.
