| 内容記述（抄録等） | By an investigation of cone-bearing ratio on each tree of Kuromatsu of residential and seaside windbreaks, roadside trees and hedges in the vicinity of Matsue City, in Sep. and Oct. of 1961., the author observed the followings :
1) Of residential windbreaks, unprolific trees seemed to decrese in accordance with the years after pruning. On prolific trees cones were found evenly on all parts of a crown, nevertheless on unprolific ones they were founnd more on an upper part of a crown, independent of planting distances and direction of a windbreak. 2) Generally speaking, about the half of trees examined are unprolific and several of them are remarkably prolific. 3) He supposes the productivity should be inherent with these trees. |
