In this paper, the effects of drought stress simulated by PEG on the photosynthesis of Populus pseudo-simonii were monitored by gas exchange and chlorophyll fluorescence techniques.

Studies on the width and density of ring and the length, shrinkage rate and their radial variations of wood fiber of Salix matsudana and Populus pseudo-simonii show that the physical properties of wood are significantly affected by its ring age,and the fiber length of wood is not influenced by ring width.

Cytospora chrysosperma and Erwinia herbicola made great changes on chemical quality of Populus pseudo-simonii×P.

Four-armed airflow olfactometer was used to determining the foraging behavior of Pteroptrix longgiclava (Girault) (Hymenoptera: Aphelinidae) and Encarsia gigas (Tshumakova) (Hymenoptera: Aphelinidae) to the essential oils which emitted from the healthy bark of Populus pseudo-simonii ×P.
