Chiba Prefectural Institute: Find cypress with no possibility of pollen flying
花粉が飛ぶ季節になりました
The pollen season has come
ヒノキは花粉症の原因の１つです
Cypress is one of the causes of hay fever
The Forest Research Institute in Chiba Prefecture has looked for trees that are less likely to fly pollen among the eight types of cypress in the Kanto region
And found two kinds of trees
One was 36% and the other was 56%. The pollen-producing male flowers did not grow and proved incapable of pollen production.
The Institute says that the two species can produce pollen-free trees
The research institute says, Planning trees without pollen to fly is good for people with hay fever.
I want to continue research so that it can be produced from around 2028.
