sempervirens L.，一个非侵入性的本地人我们推测，更大的形态可塑性可能有助于L。japonica占据了更多的生境类型，并有助于其入侵。我们比较了形态的植物提供了攀援支持与植物，没有攀援支持，从而量化了它们的形态可塑性在其栖息地的一个重要变量。这两个物种对处理的反应不同，L。粳稻表现出更大的反应，在更多的字符。例如，藤梨对攀援物的反应是节间长度减少15.3%，节间数增加一倍，地上部生物量增加43%。攀援物对羊草的节间长度和地上部生物量没有影响。sempervirens，仅导致节间数增加25%。这种可塑性可以使L. japonica能够主动地将植物模块放置在有利的微生境中，并最终影响植物适合度。
sempervirens L., a non-invasive native. We hypothesized that greater morphological plasticity may contribute to the ability of L. japonica to occupy more habitat types, and contribute to its invasiveness. We compared the morphology of plants provided with climbing supports with plants that had no climbing supports, and thus quantified their morphological plasticity in response to an important variable in their habitats. The two species responded differently to the treatments, with L. japonica showing greater responses in more characters. For example, Lonicera japonica responded to climbing supports with a 15.3% decrease in internode length, a doubling of internode number and a 43% increase in shoot biomass. In contrast, climbing supports did not influence internode length or shoot biomass for L. sempervirens, and only resulted in a 25% increase in internode number. This plasticity may allow L. japonica to actively place plant modules in favorable microhabitats and ultimately affect plant fitness.
