台湾糖业研究所自1970 年开始甘蔗组织及细胞培养 研究,近几年研究成果介绍 如下: 一、愈合组织之起源及 分化路径: 现今植物组织培养学家 对愈合组织之分化路径有两 种学说:一种是走器官形成 路线;另一种是走体胚形成 路线。台湾刘明钦等以嫩叶 片及生长点作培植体进行切 片研究,发现嫩叶片愈合组 织细胞起源于维管束紧邻之 柔软细胞;生长点愈合组织 起源于初生轫皮部细胞。他 们并在分化的愈合组织切片中发现有先生成芽鞘,然后再发生顶端分生组织及叶源。这种形状很像甘蔗种子胚之
Sugar Research Institute of Taiwan since 1970, sugarcane tissue and cell culture research, research results in recent years are described below: First, the origin of the healing organization and differentiation pathways: Today’s plant tissue culture of differentiation of healing organizations have two theories : One is to take the path of organ formation; the other is to take the formation of somatic embryos. Taiwan Liu Mingqin and other leaves and growing point for the explants of the study section and found that young leaves healed tissue cells originated in vascular bundles of soft cells in the immediate vicinity; growing point of healing tissue originated in the Department of primary cutaneous cells. They also found spermatogenic sheaths in differentiated healed tissue sections, followed by apical meristems and leaf sources. This shape is like embryos of sugarcane seeds
