Flower-bud formation in spring turnips

open access: yesEngei Gakkai zasshi, 1951
Three seasons' data on the flower-bud formation in turnip varieties may be summarized as follows: 1. It took about 50_??_60 days after sowing to reach to the period of the flower-bud formation in spring planting, and about 60_??_80 days `in autumn planting. The turnip required 20_??_30 days more than the Japanese radish to form flower-buds from sowing.
