In conse- quence understory vegetation can fill a more important role in forest ecosystems, especially in interactions （competi- tion or facilitation） between understorey vegetation and forests trees that might affect tree growth and nutrition. Considerable research has been carried out on plant inter- ference. However, the experimental designs used in these studies vary from one study to another, and from species to species depending on the aims, objectives and practicalities of the studies. Thus there is no optimum design for com- petition experiments. This review discusses designs avail- able in studying plant interferences in a glasshouse, particularly the effects of below-ground interaction of understorey vegetation and forest trees.展开更多
