Dissertation Research: A Biosystematic Study of the Genus Hosta

在导师塞缪尔·琼斯博士的指导下， 在格鲁吉亚大学，Myong Chung先生将研究 形态学、染色体组成和遗传模式 韩国和日本单子叶植物种的变异性 玉簪，园艺上重要的玉簪百合的来源。 在韩国和日本的许多种群已经被收集， 学生在过去几年中，并从这些样本， 其他藏品将为植物标本馆提供材料， 实验室研究 物种之间的遗传障碍将是 通过人工杂交程序进行评估， 公共花园实验，部分是为了测试物种是否 生殖隔离。 电泳技术正在 用来测量物种间基因差异的数量， 集中在一个属的七个物种的子集估计， 在自然界中有20种左右。 玉簪百合，原产于 东亚，在分类学上处于混乱状态， 该项目将有助于建立一个可靠的基础， 鉴定和推断进化关系 各种形式。

Under the guidance of faculty adviser Dr. Samuel Jones at the University of Georgia, Mr. Myong Chung will study the morphology, chromosome composition, and patterns of genetic variability in Korean and Japanese species of the monocot genus Hosta, source of the horticulturally important hosta lilies. Numerous populations in Korea and Japan have been collected by the student over the past few years, and samples from these and other collections will provide materials for herbarium and laboratory studies. Genetic barriers between species will be evaluated through a program of artificial hybridizations in a common-garden experiment, in part to test whether species are reproductively isolated. Electrophoretic techniques are being used to measure amounts of gene differences between species, focusing upon a subset of seven species in a genus estimated to have 20 or so species in nature. The hosta lilies, native to eastern Asia, are in a taxonomically confused condition, and the project will help establish a reliable basis for species identification and for inferring evolutionary relationships among the various forms.
