vernalization experiment of carrots

Abstract

This study was carried out to ascertain the effects of cold storage of seeds on the flower-bud differentiation and bolting of carrots. The varieties used were Kokubu, Kintoki and Gosun.
(1) The influence of vernalization (at 2_??_3°C for 1, 2 and 3 months) on the flower-bud differentiation and bolting of carrots was clear, though the response of each variety to the vernalization was not same.
(2) The variety Kintoki was the most sensitive to the vernalization treatments, and the Kokubu was the least.
(3) In this experiment two months treatments showed the most effective influence upon the flowering.
