Specific leaf area and leaf dry matter content of plants growing in sand dunes
We investigated the variations in specific leaf area (SLA) and leaf dry matter content (LDMC) of 20 species (10 annuals and 10 perennials) that have different distributional patterns in the Kerqin Sandy Land in northern China. The main purpose of our study was to determine if SLA and/or LDMC could be used as indicators of plant resource-use strategy in sand dune environments. The selected speci...
متن کاملIs leaf dry matter content a better predictor of soil fertility than specific leaf area?
BACKGROUND AND AIMS Specific leaf area (SLA), a key element of the 'worldwide leaf economics spectrum', is the preferred 'soft' plant trait for assessing soil fertility. SLA is a function of leaf dry matter content (LDMC) and leaf thickness (LT). The first, LDMC, defines leaf construction costs and can be used instead of SLA. However, LT identifies shade at its lowest extreme and succulence at ...
متن کاملConvergence in leaf size versus twig leaf area scaling: do plants optimize leaf area partitioning?
BACKGROUND AND AIMS Corner's rule states that thicker twigs bear larger leaves. The exact nature of this relationship and why it should occur has been the subject of numerous studies. It is obvious that thicker twigs should support greater total leaf area ([Formula: see text]) for hydraulical and mechanical reasons. But it is not obvious why mean leaf size ([Formula: see text]) should scale pos...
متن کاملSpecific leaf area and dry matter content estimate thickness in laminar leaves.
BACKGROUND AND AIMS Leaf thickness plays an important role in leaf and plant functioning, and relates to a species' strategy of resource acquisition and use. As such, it has been widely used for screening purposes in crop science and community ecology. However, since its measurement is not straightforward, a number of estimates have been proposed. Here, the validity of the (SLA x LDMC)(-1) prod...
متن کاملLeaf Area Calculating Based on Digital Image
A new and simple method for plant leaf area measurement using image processing technique was provided. Sixty leaves with different shape and size of six plant species were selected for study. The software using for image processing and leaf area calculation was matlab6.0. Experiments were performed to test the performance of the estimating system by comparing the estimated leaf area with the gr...
