Body

A short term greenhouse study was used to examine the vegetative effects of spotted knapweed (Centaurea maculosa) when grown in different light and competitive conditions and clipped at varying intensities. Two inter-specific and 2 intra-specific competitions were created in the green house by planting the pots to 4 different plant combinations. Each pot was subjected to three levels of light intensity (full, 2/3, and 1/2) and 7 defoliation treatments (varied in frequency, severity and stage of growth).
