万寿菊

The genetic relationship and genetic diversity of genus Tagetes could be assessed efficiently by ISSR markers.

利用ISSR标记技术可较准确分析万寿菊属材料间的亲缘关系及遗传多样性。

Any of various American plants of the genus Tagetes, widely cultivated for their showy yellow or orange flowers.

万寿菊'。''''。'属'。''的生长于美国的植物，因其开有鲜艳的黄色或桔黄色花而被广泛种植

Genetic relationship of 29 accessions of Tagetes erecta and 2 accessions of T. patula were analyzed using ISSR markers.

对29份万寿菊材料及2份孔雀草材料利用ISSR分子标记进行遗传关系分析。

of extraction,separation and purification of lutein from marigold Tagetes erecta Linn.

研究了利用正己烷和乙醇混合溶剂，或石油醚溶剂，从万寿菊花粉提取、分离、提纯叶黄素的方法。

ISSR markers were used to study the genetic relationship and investigate the genetic diversity and genetic structure for providing a theoretical basis and technical support for appropriate conservation and application of existing genetic resources of Tagetes.

通过ISSR分子标记研究品种资源遗传关系，探讨其种群遗传多样性水平和遗传结构，为了解品种间遗传多样性、品种间亲缘关系、育种及科学合理保存和利用现有万寿菊属种质资源提供理论依据和技术支持。

The genomic DNA of 31 accessions of genus Tagetes was amplified with 11 primers, the bands produced by each primer ranged from 5 to 11, and 6.8 bands were obtained on average, the polymorphic loci ranged from 40%-100%.

用11个引物对31份万寿菊属材料进行PCR扩增，每个引物扩增的ISSR条带数在5-11条，平均每条引物能扩增出6.8条带，多态位点百分率为40%-100%。

The analysis of parents using AFLP markers showed that there were more than 3.96% background differences in heredity between parents, which were much more than theoretical value. It indicated that there was a large conservative region near male sterile genes within Tagetes erecta genome, in whichgenes are closely linked to each other.

通过AFLP标记技术对亲本的分析，发现亲本间存在不低于3.96%的遗传背景差异，远较理论值高，说明万寿菊基因组中在雄性不育基因附近存在比较大的保守区域，该区域基因间存在着比较紧密的连锁关系。

Research was conducted on the inhibitory effect of the volatile oil on several plant pathogenic fungi. Fungal colony diameter was measured in the inhibition experiments which indicated the presence of substances with antifungal activity in the roots of Tagetes patula. These results provide a valuable reference for development of fungicides.

对挥发油对几种植物病原菌的抑菌活性作了研究，抑菌实验采用菌落直径法，研究结果表明，万寿菊根的挥发油中含有抑菌活性物质，该实验可为开发新的杀菌剂提供有价值的参考。

In this present study, sterile hybrid progenies derived from optimal combinations guaranteed the protection of intellectual property. Meanwhile, inter and intra-specific hybridization using male sterility and molecular method for hybrid seed identification paved a new way for crossbreeding Tagetes erecta through male sterility.

本研究所选育出的优良组合子代全部是不育类型的杂种，有力地保护了自主知识产权，利用雄性不育进行种内和种间杂交以及分子鉴定杂交种的方法，开创了万寿菊利用雄性不育进行杂交育种的新途径。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
