Developmental Inherent Rhythm and Dynamic Changes in Cell Ergastic Substances of Secondary Vascular Tissues in Populus deltoids;

Study on Plant Regeneration of Excised Leaf from Populus deltoids(I-63×I-69);

The Rust Resistance of Populus deltoids Cultivars to Melampsora larici-populina;

Differentiation in a secondary xylem vessel element of Populus deltoides using ultrastructural analysis;

The Variation of Inner Physiological and Biochemical Characters Under Flooding Stress of Populus deltoides Clones;

Effects of Flooding Stress on the Activity of Cell Defensive Enzymes of Populus deltoides Clones;

The Genetic Stability Analysis of Growth for New Cottonwood Clones;

Water and Temperature Change Model and Energy Consumption During High Temperature Drying of Cottonwood;

The variations within trees of microfibril angle(MFA) were inverstigated in three 6-year-old cottonwood clones: 366, 370, I-69.

Study on tissue culture techniques of triploid Populus tremula;

This study was performed to establish a method for single chromosome microdissection and microcloning in forest plants using poplar(Populus tremula) as a model.

The Populus euphratica calli were cultivated to study its salt tolerance ,which was compared with Populus tremula.

The dynamic analysis of height, DBH, and volume were done based on the data taken from 12 years plantation of clones of Poplus deltoides (I-69)× P.
