It was studied the fertility, type, and size of pollen inspecies of Angelica, Cnidium, Bupleurum and a few different kind of Umbelliferae's, in order to adapt the practical cultivation.
Material are treated in Aniline blue lacto phenol for 24 hours in room temperature and count the stained grain (×70, × 100) an microscope. It was adopted Ikuse's method in size and type judgement.
As a result,
the type of pollen grain : prolate, perprolate, triangle
the size of pollen grain : 37.6~24.0μ in length, 20.8~12.0μ in width common size : 32μ long, 10μ wide
fertility : Species of Angelica and Cnidium are generally high. Cnidium officinale Makino's is 9%
Low fertility plant use Radix, high ones use seed.
