Effects of Defoliation on Growth and Reproduction of Brazilian Peppertree (Schinus Terebinthifolius)

摘要: Abstract The exotic Brazilian peppertree is a serious invader of both disturbed and natural areas in central south Florida, forming fast-growing, impenetrable thickets that dominate entire ecosystems. has been targeted for biocontrol, two defoliating insect species may eventually be released. This study was done to consider the possible effectiveness biocontrol agents. research investigated effects different frequencies defoliation on height, crown diameter, berry production young peppertrees. All foliage manually clipped from 36 trees field plots once or twice per year ≥ 1 yr. effect clipping 100% leaves scattered individual branches one large also examined. Trees were completely defoliated five times at 6-mo intervals significantly smaller produced fewer fruits than undamaged controls. Plants time only, two...
