以木薯品种UnB 201和UnB 122为砧木，用木薯接穗嫁接木薯，进行解剖学研究。切下根，用番红和阿辛蓝染色，用显微镜检查，并与未嫁接根的切片进行比较。结果表明，砧木中的维管束、周鞘纤维和纤维素的数量明显减少。它们显示出明显更大的血管。解剖结构的这些变化是遗传物质从接穗转移到砧木所引起的遗传效应的结果。比较了相同的未嫁接物种。这是第一次报告解剖变化，由于木薯嫁接。
Cassava rootstocks of varieties UnB 201 and UnB 122 grafted with scions of Manihot fortalezensis were prepared for anatomic study. The roots were cut, stained with safranin and alcian blue, and examined microscopically, comparing them with sections taken from ungrafted roots. There was a significant decrease in number of pericyclic fibers, vascular vessels and tyloses in rootstocks. They exhibited significant larger vessels. These changes in anatomic structure are a consequence of genetic effects caused by transference of genetic material from scion to rootstock. The same ungrafted species was compared. This is the first report on anatomic changes due to grafting in cassava.
