Relationships between shoot length, bud number and branch production in Quercus petraea (Matt.) Liebl
1992
Harmer, R.
Over a 3-year-period the relationships between shoot length, number of buds and branch production were investigated on the leading shoots and major crown branches on 10-year-old Quercus petraea. The pattern of growth was similar in leading shoots and branches indicating that for some aspects of growth observation of branches can substitute for study of the leader. There were significant relationships between shoot length and either number of buds or branches, and between number of buds and branches; some of the relationships differed between years. There were significant between tree differences in the proportion of buds forming branches. Failure of the terminal bud increased lateral branch production. The overall shape of the crown was related to the average annual extension growth. Results are discussed in relation to prediction of crown development and the selection of superior genotypes in a tree improvement programme.
