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 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 کاملMapping forest leaf dry matter content from hyperspectral data Abebe
Leaf dry matter content (LDMC) is a central vegetation property that plays an important role in assessments of ecosystem functions. In this study, LDMC was estimated from hyperspectral airborne image by inversion of the INFORM radiative transfer model using Continuous Wavelet Analysis (CWA). Stand parameters were collected for 33 sample plots during a field campaign in July 2013 in the Bavarian...
متن کاملQuick Estimation of Apple (Red Delicious and Golden Delicious) Leaf Area and Chlorophyll Content
ABSTRACT- The evaluation of leaf area and leaf nutritional value is important for crop growth modeling and estimations of its performance. The purpose of this study was to use image processing techniques to develop an economical method to ease the assessment of nutrient status and leaf area (LA) of plants and to compare the outcomes of this method with linear models. Leaf area and leaf chloroph...
