罗田苍术形态及性别遗传观察研究

摘要

罗田苍术为茅苍术的一个亚种,本文通过对罗田苍术植株形态及性别遗传进行观察和研究,结果发现,罗田苍术植株较为高大,根茎呈连珠状或结节状,挥发油含量高,药材质量优;叶片较大,花序顶生,总苞片层数6-8.花多数,两性,或单性,在自然条件下主要通过根茎无性繁殖,这是长期以来罗田苍术对其生长环境响应的结果.罗田苍术无性繁殖植株性别的稳定性,为单性花和两性花植株药用成分差异性研究奠定了基础,从而为罗田苍术栽培用种是否考虑植株性别提供了理论依据.%Luotian atractylodes rhizome is a subspecies of atractylodes lancea, through observation and research on Luotian atractylodes plant morphology and sex heredity, the results showed that Luotian atractylodes plants are tall, the rhizome was beaded or nodular, high content of volatile oil, with good medicinal quality;larger leaves, inflorescences, 6-8 bracts layers.Numerous flowers, bisexual or unisexual, mainly through rhizomes asexual reproduction under natural conditions, it is a result for Luotian atractylodes to responde to environment.The stability of Luotian atractylodes' asexual reproduction laid the foundation for the unisexual and bisexual flowers differences of plant medicinal ingredients, so as to provide a theoretical basis for cultivating Luotian atractylodes if considering the plant sex or not.
