Studies on the tillering primordium and tillering bud in rice seedlings : (6) The influence of seeding depth on the development of tillering primordium and tillering bud : II. In the case of Flooding condition

Abstract

1. This experiment was made in the same way as described in the 5 th report except that it was carried out under flooding condition. 2. Seeding depth was 0.5 cm, 1 cm, 2 cm, and 3 cm. 3. The result of experiment is summarized as follows. The development of tillering primordium and bud observed under each seeding depth, was generally the same as observed under not flooded condition, that is, good developments & growth for shallow sowing, and as the sowing becomes deeper the growth was retarded. However, the difference of the development of the each tillering bud induced by the different seeding depth was much greater than that under the not flooded condition.
