Theoretical research on a model for predicting the shadow boundary of an individual conical crown on a slope;

Crown profile models, including branch diameter, branch length, angle of origin, and branch chord length, were developed from branch attributes and tree variables.

Models for simulating locational distribution of total branches, both along and around the bole, and for estimating crown profile of primary branches within live crown were developed in a 26-year-old Larix olgensis plantation based on the circular branch analysis technique.

Study on the affect of the crown-fullness ratio on the growth of the tree and the form of the tree-trunk;
