摘要
本文首次报道了名贵经济植物番红花球茎发育过程中的解剖学研究。结果表明:番红花球茎增粗生长是由于细胞分裂与细胞体积增大。细胞分裂几乎分散在整个轴上,没有初生增粗分生组织。在新球茎基部通常产生一条粗壮的收缩根。收缩根的维管组织与新球茎、老球茎紧密相连接。
The primary thickening grow of the corm of Crocus sativus occured throuhgh cell division and cell enlargement.The.cell divisions were diffused almost in the whole axis,and no primary thickening meristem occured.Generally,a thick contractile root grew on the base of the new corm.The vascular tissue of contractile root was ciose associated with the new and old corms.
