猕猴桃属

The plants of Actinidia are of great economic importance. And the taxonomy of Actinidia was very difficult and confusing. The genus Actinidia was established by Lindley in 1836 based on the specimen Wallich 6634 collected by N. Wallich in Nepal in 1821. Comprehensive studied on the taxonomy of the genus were carried out by Dunn, H. L. Li, and C. F. Liang.

猕猴桃属植物具有极大的经济价值，而且该属是分类上极其困难的属之一。1836年英国植物学家John Lindley根据Nathaniel Wallich 1821年在尼泊尔采集的标本Wallich 6634号建立了Actinidia即猕猴桃属，Dunn和李惠林及梁畴芬曾对该属进行过全面的研究。

The characters of reproductive and vegetative organs of Actinidia exhibit considerable variation, and correlation between characters is poor.

猕猴桃属的生殖器官和营养器官都呈现出来很大的变异幅度，而且性状之间的相关性比较缺乏。

The purpose of research aimed to discuss a method of extracting the total genomic DNA from Actinidia.

The genus Actinidia contains more than 66 species and 118 taxa.

摘 要 猕猴桃属植物全世界有66个种、约118个种下分类单位。

I examined the specimens deposited at PE, KUN, IBK, IBSC, and HIB. And I required to take a lot of photos of type specimens in Harvard University Herbarium and several photos of type specimens in the herbaria in China, or downloaded some photos of type specimens at the website of NY, K, US, and HK. I went to Yunnan, Chongqing, Guizhou, Hubei, Hunan, Guanxi to collect specimens and observed the kiwifruits cultivated in Wuhan Botanical Garden and Guangxi Institute of Botany. With reference to the results of previous authors, I recognized 52 species including 16 varieties of Actinidia.

作者查阅了中国科学院植物研究所国家植物标本馆、昆明植物研究所标本馆、广西植物研究所标本馆、华南植物园标本馆、武汉植物园标本馆的标本，并请求哈佛大学同行拍摄了大量保存在国外的模式标本的照片，从国外和国内一些标本馆相关的网站上下载一些模式照片，请求国内的同行帮助拍摄了少数模式标本的照片，到云南、重庆、湖北、湖南、广西、贵州进行野外考察，在武汉植物园和广西植物所的猕猴桃资源圃中对栽培的猕猴桃属植物进行观察，结合文献资料，对猕猴桃属植物的分类进行了全面的研究。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
