甘蔗的直线生长是蔗的一个极为复杂的生理现象。它发生在蔗茎的分生组织,在这里由于细胞的分裂和扩大,不断形成新细胞使直线生长现象明显。细胞的分裂过程虽只局限于分组织之处,但细胞的伸长则扩展到前面几个未成熟的节间,并随着与梢端距离的增加而递减。细胞分化的分生组织也是高度同化的中心, The straight growth of sugarcane is a very complicated physiological phenomenon. It occurs in the meristems of cane stems, where the continuous growth of new cells makes linear growth evident by the division and expansion of cells. Although the cell division process is confined to the sub-organization, but the cell elongation extends to the first few immature internodes, and as the distance from the tip increases. Mesenchymal cell differentiation is also a highly homologous center,
