| 摘 要： | 峨优1号Chimonobambusa quadrangularis ’Eyou 1‘属于竹亚科Bambusoideae方竹属Chimonobambusa Makino的方竹Ch.quadrangularis（Fenzi） Makino，2004年发现于四川省乐山市峨边县大堡镇，随后作为笋用竹在大堡镇引种栽培，是方竹变异植株经人工驯化、培育而成的栽培竹新品种。‘峨优1号’与方竹栽培型‘Quadrangularis’的关键区别在于：前者中上部秆环甚隆起，竹秆多见"之"字形弯曲，秋季笋期10月上旬至11月中旬，春季在土层深厚肥沃处有2次发笋现象，去箨笋节呈明显翠绿色；后者中上部秆环不及前者隆起，竹秆通直，秋季笋期9-10月，春季无二次发笋现象，去箨笋整体偏黄。

| Abstract: | Chimonobambusa quadrangularis "Eyou 1" is a new bamboo cultivar from Ch. quadrangularis in the genus of Chimonobambusa Makino of Bambusoideae. It was found in Dabao Town, Ebian County, Leshan City, Sichuan Province in 2004, and then introduced and cultivated in Dabao town as a shooting bamboo. The new cultivar was developed by artificial domestication and cultivation from the variation plants of Ch. quadrangularis(Fenzi). The key differences between ‘Eyou 1’ and ‘Quadrangularis’ are that the middle and upper culm rings of ‘Eyou 1’ are very raised and the bamboo culms are often zigzag. The shooting period in autumn are from early October to mid-November, and in the spring, there are secondary shoots in deep and fertile soil. The bamboo shoots without sheathes show emerald. In contrast, the culm rings of the ‘Quadrangularis’ are not higher than those of the former and the culms are straight. The shooting period in autumn are from September to October, no secondary shoots in spring and the bamboo shoots without sheathes are yellow. |
