摘要
介绍了导管及其穿孔板的研究进展,包括导管的特征 穿孔板的类型、多穿孔板与侧壁穿孔板、纹孔膜残留 ,导管的起源与穿孔板的演化,蕨类植物、裸子植物与被子植物导管的比较,并就导管进化与穿孔板演化,导管的二型性现象、侧壁穿孔板、多穿孔板与穿孔中纹孔膜,生态对导管进化的影响等方面以及对今后的研究作了展望.
The research progress in the vessels and perforation plates of the vascular plants, including characters of vessels (including the type of perforation plates, multiple and lateral-wall perforation plates, pit membrane remnants), the origin of the vessels and specialization of the perforation plates, were summarized. The vessels and the perforation plates of ferns, gymnosperms and angiosperms were also compared.Some considerations for future researches of vessels and perforation plates in vascular plants were propsed.
