摘要
采用离析法和光学显微技术,对苹果和山梨木质部导管细胞的类型、所占比例及导管细胞的长度和口径,纤维细胞的长度和口径进行了比较解剖研究.结果表明:两种材料导管类型相同,但所占比例不同;山梨木质部导管要比苹果木质部导管长且宽;山梨的纤维细胞长度和口径比苹果的纤维细胞长度和口径大,且长度上差异明显.
Using segregation process and optical microscopy, the type and proportion of vessel cells in xylem of Malus dornestica and Pyrus ussuriensis maxim, as well as the length and diameter of the vessel cells, the length and diameter of the fiber cells were carried on the comparative anatomy studies. The results show that the type of vessel cells is identical, but the proportion is different. The vessel cells of Malus domestica are longer and wider than that of Pyrus ussuriensis maxim. The length and diameter of the fiber cells of Pyrus ussuriensis maxim are larger than that of Malus domestica, and the difference in length is obvious.
