Selection of appropriate size part and shape of a crude drug is very important in obtaining a good section.
In cas eof stem/root/stolon, select a portion of drug having a diameter of of 3 to 5mm and length of 25cms.
A sample shorter in length will be difficult to hold and sample thicker in diameter may give rise to thick and wedge shaped sections.
