【摘要】 <正> 竹子是禾本科(Gramineae)竹亚科(Bambusoideae)竹类植物的总称。全世界约有78属1400多种,生长在热带和亚热带地区。我国地处世界竹子的分布中心,是主要产竹国之一。 竹子细胞染色体方面的研究,据文献所查,国外已有60多年的历史,对许多种和变种、类型作了染色体计数,而国内除许建昌教授(台湾)外,严天民、张光楚等近年也有报道,到目前为上,约有29属的150多种和变种、类型有染色体资料。更多还原

【Abstract】 This paper deal with numbers of chromosome for Bambusoideae. The chromosomes of the somatic cells in the root tips of some plants of Bambusoideae were observed. The chromosomes counts of 9 species belong to 3 genera; Bambusa, Phyllostachys, Pseudosasa. On these numbers of chromosome, 7 species are reported here for the first time.The present records are as follows: Bambusa ventricosa McClure 2n = 72, Phyllostachys atrovaginata Chao et Chou 2n = 48, Ph. fimbriligula Wen 2n = 48, Ph. heterocycla var. pubescent (Mazel) Ohwi. 2n = 48, Ph. heterocycla var. pubescens f. nabishimana 2n=36, 48, Ph. nigra Munro 2n = 48, Ph. praecox Chu et Chao 2n = 46, Ph. prominent Xiong 2n = 44, 48, Pseudosasa amabilis Keng f. 2n = 48.更多还原
