Preliminary Report on Cross - breeding of Tagetes erecta

万寿菊杂交育种 实验初报

Analysis of the chemical composition of Tagetes erecta ( I ) & Analysis of the composition of essential oils in Tagetes erecta by GC / MS

万寿菊化学成分的研究（I）&万寿菊挥发油的GC/MS分析

Study on Rapid Tissue-culture of Isolated Laminae from Tagetes erecta

快速离体培养 万寿菊 植株叶片组织

It was identified that male sterility of Tagetes erecta was Nucleo-Cytoplasmic interaction type with the characteristics of environment insensitiveness and stable inheritance and was qualitatively controlled by a recessive gene in nucleus .

研究证实了雄性不育性 属 核质互作型雄性不育，且主要受一对细胞核基因控制的隐性不育，可育对不育显性，雄性不育是质量性状，不受环境影响，可稳定遗传。

This result indicated that Tagetes erecta can be used in the cross breeding and hybrid production through three lines combination .

这一 遗传 特性表明， 万寿菊可通过三系配套，用于杂交种选育和生产。

Study on Variety Selection and Cultivation Technique of Tagetes erecta for Pigment

提色素 用 万寿菊品种筛选和种植技术的研究

To improve survival rate and cultivation cost of herbaceous flowers a comparative study of planting Tagetes erecta Dahlia pinnata Zinnia elegans and Coleus blumei are carried out in nursery big shallow flowerpots and 72 × 24 hole flowerpots with different combination of the base materials .

为提高草本花卉的育苗成活率，降低育苗成本，对 万寿菊、大丽花、百日草、彩叶草等植物采用不同基质配比，以圃地、浅底大盆和72×24穴盆方式进行播种对比研究。

The regulatory functions was the most obvious for Celosia cristata followed by Dahlia hybrida and Begonia × hiemalis Tagetes erecta relatively had a poor result .

对鸡冠花调控作用最为明显，其次为小丽花和丽格海棠， 万寿菊效果相对较差。
