Shoot and crown development of alfalfa (Medicago sativa L.) seedlings when defoliated at different regrowth intervals

摘要：

Alfalfa ( Medicago sativ a L.) is the most productive and long‐lived temperate legume under intensive cultivation.Longevity is promoted by the vigorous development of persistent crowns (Teuber and Brick.,1988).However, seedling establishment is often disturbed by improper management such as too frequent defoliationand shading caused by high initial seedling densitybringing about poorer crown development.This work examined morphological tendencies in branching habit and crown formation in alfalfa seedlings when defoliated at different intervals.
