Description
In the northern Hokkaido, Quercus dentata Thunb. and Quercus mongolica var. grosseserrata Rehd. et Wils. have two main bud bursting styles. One of them is the inland type and it is sure to burst from terminal bud.
In the contrast with this, the coastal type does not have bursting from upper buds such as terminal bud, terminally lateral buds and upper lateral buds. That is, bud burst only from lower lateral buds in the coastal forest.
In this paper, the author deal with a relationship between bud bursting style and seeding style. The seeding style was given a defintion as follow. What bud part of two years old shoot did one year old shoot with spike burst from and what bud part of one year old shoot did spike grow on.
The results obtained are as follows :
1) Whenever one year old shoot had spikes, they were burst from upper buds (inland type) , even if, in the natural coastal forest zones.
2) The spikes that were grown on the one year old shoot were always taken the places of terminally lateral buds part and the upperest lateral bud part.
3) One year old shoot burst from terminal bud and spike grew on the terminally lateral buds part are the most common seeding style in inland forest. However, in the coastal zone, one year old shoot burst from upper part bud (terminal bud, terminally lateral buds and upperest lateral bud) and spike grew on the terminally lateral bud part.
4) Terminal buds are the most important organ, because they reserve the generative functions such as spikes. So, they are larger than orther part buds.
5) In the coastal forest, not only terminal bud but also ternimally lateral buds and upperest latewral bud had spikes. From this seeding style, it is suggested that terminally lateral buds and upperest lateral buds become more and more larger in the coastal forest.
