Abstract

To quantify the effect on genetic diversity of restoringtree populations in an area under the influence of an urban heatisland, we evaluated the genetic diversity of 72 Ceiba aesculifoliaindividuals, from a restoration experiment established from 2170to 2260 m a.s.l. Reintroduced individuals were compared with theprovenance from which the seeds were obtained, and two externalprovenances, for a total of 123 individuals. Samples were analyzedwith three AFLP primer combinations. Polymorphisms of 38.4 to62.5% were obtained. Genetic diversity estimated with the Simpsonindex ranged from 0.14 to 0.2. The provenances in the restorationsite had higher diversity than the provenance that originated theseeds. Groups formed with provenances with similar genetic diversity(no statistical differences) also shared similar Bayesian mixtureproportions. Having higher genetic diversity in restored provenancesthan in the provenance that originated the seeds can be favorable asthe conditions in the site change in the future due to the expectedincrease in the urban heat island effect as the nearby city expands.

城市热岛内木棉种源恢复的AFLP多态性

为了量化在城市中心岛影响下恢复树木种群的遗传多样性，我们评估了从2170到2260 m的恢复实验中获得的72个木棉的遗传多样性，并将重新引入的个体与获得种子的种源和两个外部种源进行了比较，共123个个体。用三种AFLP引物组合对样品进行分析。多态性为38.4% ~ 62.5%。simpson指数估算的遗传多样性范围为0.14 ~ 0.2。恢复地的种源多样性高于原种源。具有相似遗传多样性(无统计学差异)的种源组成的群体也具有相似的贝叶斯混合比例。随着附近城市的扩张，预计城市热岛效应会增加，因此，恢复种源的遗传多样性比原种源的遗传多样性更高，这对未来场地条件的变化是有利的。

期刊介绍： Phyton-International Journal of Experimental Botany is an international journal that publishes on the broadest aspects of plant biology and ecology. The journal welcomes the original and exciting submissions that provide new and fundamental insights into the origins, development, and function of plants from the molecular to the whole organism and its interactions within the biotic and abiotic environment. Phyton-International Journal of Experimental Botany publishes outstanding research in the plant and ecology sciences, especially in the areas of plant physiology and biochemistry, plant metabolism, plant ecology and evolution, as well as those making use of synthetic, modeling, bioinformatics, and -omics tools. Manuscripts submitted to this journal must not be under simultaneous consideration or have been published elsewhere, either in part or in whole.
