'De Cicco' cultivar was used in study the effect of the sowing time on the flower bud differentiation and development. Seeds were sowing on May 15th, 25th, June 5th and 15th respectively. The results obtained are as follows; 1. The initiation of terminal curd appeared with 11~12 expanding leaves on the average 50 days after sowing. Integrate temperature from sowing to flower bud differentiation was 1061±23.2℃. 2. Number of days from sowing to flower bud differentiation and curd appearance were decreased by late sowing, while weight and diameter of curd were increased by early sowing. 3. Appearance of lateral shoot was almost same time as the terminal flower bud differentiation. Lateral shoots appeared nearly 10~16 above 6th~7th nodes on a plant. Lateral shoots on 8th~11th nodes appeared early, and on 11th~17th nodes grew vigorously. 4. The time of flower bud differentiation on the lateral shoot was independent of the appearance order and size of the shoot. The earliest shoot curd formed was the shoot on the nodes of 3~5 below the terminal curd.
