Liana Root Systems, Root Foraging Efficiency, and Competitive Interactions with Trees

原产于中北部的树木和藤本植物的根系 佛罗里达将根据形态进行比较，最大 深度和效率的殖民化资源丰富的卷 土壤 藤本植物和树木的异速生长研究将阐明 在以下比例的差异：根：地上部生物量;叶 面积：根表面积;叶面积：茎横截面积;以及， 根：根生物量。 此外，P.I.将决定 密集缠绕的藤本植物抑制树苗生长的程度 通过地下和地上的竞争来实现增长。 藤本 根和茎一样， 功能，因此地下生物量可以分配给 最大限度地利用土壤的水分和养分。 藤本植物根系预计将是非常机会主义的， 分布，因此比树根更频繁地受益 从水和养分的时空变化 空房的 树木和藤本植物在根上的差异 觅食效率将通过实验确定。

Root systems of trees and lianas native to north-central Florida will be compared on the basis of morphology, maximum depth, and efficiency of colonization of resource-rich volumes of soil. Allometrical studies of lianas and trees will elucidate differences in the following ratios: roots:shoot biomass; leaf area:root surface area; leaf area:stem cross sectional area; and, root:root biomass. Additionally the P.I. will determine the degree to which dense tangles of lianas suppress tree seedling growth through competition belowground and aboveground. Liana roots, like their stems, do not serve a mechanical support function and thus belowground biomass can be allocated to maximize the volume of soil explored for water and nutrients. Liana root systems are expected to be extremely opportunistic in distribution and thus benefit more frequently than tree roots from spatial and temporal variation in water and nutrient availability. Differences between trees and lianas in root foraging efficiency will be experimentally determined.
