As treatment with jasmonic acid was predicted to negatively growth, our results of root and shoot biomass supported this hypothesis. Our results of inhibited growth are consistent with previous studies show jasmonic acid as a growth inhibitor to plants (Dathe et al. 1981; Redman et al. 2001; Koussevitzky et al. 2004). Root weight for treated plants were significantly lower than root weight for control plants. Previous literature shows that root growth of plants treated with jasmonic acid should be significantly effected (Yu et al. 2000; Tung et al. 1996). However, it has been shown that jasmonic acid deters herbivores from consuming the roots of the plant (Lu et al.). Although root mass was significantly affected by treatment, the roots of these plants may be less preferable to herbivores. This is something that would require further experimentation.
