| 摘 要： | 虽然在甘蔗同节上出现多芽现象已被报道,但是却未曾发现同节多芽能独立生长成蔗茎的现象。文章阐述了2008～2009年度在甘蔗品种CoS 96268宿根蔗大田观察到的一株甘蔗植株上发生的独特的形态分离现象。在该株甘蔗地上部的第7、8节上均有2个芽,但第8节出现溢痕,将该节间分成不等的两部分;该分离部分在第9节间更为明显,并独立生长成两条蔗茎（分枝）,每条蔗茎均具有正常的节间形态。

| Abstract: | Occurrence of multiple buds on the same internode in sugarcane has been reported in the literature but after the presence of multiple buds, independent cane growth has not been reported yet. The present paper illustrates about a field observation where a unique morphologic deviation was observed in ratoon crop of sugarcane variety CoS 96268 during the crop season 2008-09. In this plant, 7th internode, above the field, had two buds, the 8th internode also had two buds but a constriction appeared to divide the internode into two, of course not well defined, halves. This division, however, became more prominent in the 9thvg internode. Above this internode cane bifurcated and the two stalks (branches) grew independently and produced internodes in a normal fashion. |
