Ochikarawere studied in morphology. The results indicates that the Oochikara has lateral root primordium and lateral root, and RM109 has no those. The number of pericycle cells in protoxylem of RM109 reduces to the 77% of that of Oochikara ; the number of vessel in metaxylem increases, and the number of vessel Ⅰ is the 149% of that of Oochikara ; the number of vessel Ⅱ is the 321% of that of Oochikara ; and the vessels arrange disorderly.

Pekinensis . IAA at concentration of 0.4-1. 0 mg/L in solid MS medium incited many adventitious roots on hypocotyl segments. The earliest anatomic changes were observed on cut surface of hypocotyl segments under optical microscope 24 hours after IAA treatment: cytoplasmic and nuclear density became higher in a few of parenchytmatous cells adjacent to phloem in tissue of pericycle, followed by cell divisions.
在生长素诱导24h后，可借助显微切片观察到下胚轴切面附近明显的解剖学变化：首先是中柱鞘内靠近韧皮部的薄壁细胞的细胞质与细胞核变浓，染色加深，部分细胞分裂；随后是分裂的细胞团增大，逐渐形成根原基并分化出根冠。
