Method of investigation on tree phenology was examined to obtain the basic data to make clear the yield forecast of acorns of Quercus crispula trees. We developed the new method of tree phenology to get objective data using photographs.Relationship between the numbers of female flowers and matured acorns was investigated. The number of female flowers was decreased in a poor crop year, but the ratio of the numbers of female flowers and matured acorns was same value.Relationship between the mass of leaves and mature acorns was investigated. There was no relation in each mass.Relationship between the mass of mature acorns and the width of annual rings was investigated. But we could not obtain the sufficient data to make clear the relation. This survey will be continued.Relationship between the tree phenology and the process of wood cell formation using pin-marking method. It was cleared that the trachea was formed before bud opening. But we could not make investigate the cell form when the acorn was matured because of poor crop years.Number of female flowers was very important factor for estimation of acorn production.

对树木物候调查的方法进行了探讨，为明确皱皮栎橡子产量预测提供了基础数据。我们发展了树木物候学的新方法，利用照片获得客观的数据，研究了雌花数与成熟橡子数的关系。结果表明，在歉收年份，雌花数减少，但雌花数与成熟橡子数之比保持不变，叶片质量与成熟橡子数之间存在一定的关系。结果表明，成熟橡子的质量与年轮宽度之间无相关性。但我们无法获得足够的数据来阐明这种关系。树木物候与木材细胞形成过程关系的针点法研究。明确了芽开放前气管已形成。但由于连年歉收，无法对橡子成熟时的细胞形态进行研究，因此，雌花数是衡量橡子产量的重要指标。
