Research progress on leaf mass per area

doi:10.17521/cjpe.2015.0428

Abstract

Abstract:

Leaf mass per area (LMA) is a composite structural parameter as well as a basic leaf functional trait in the leaf economics spectrum (LES). It is not only closely related to many physiological responses of plants, but also can measure the investment of dry mass per unit of light-intercepting leaf area. LMA is considered an important indicator of plant ecological strategies and has been studied widely in plant ecology, agronomy, forestry, and plant physiology. This paper elucidates the structural analysis and computational methods of LMA at the organizational scales of whole leaf, tissues and cells, examines the influence of LMA on photosynthesis, and discusses the inherent differences in LMA and the responses of LMA to environmental stresses (temperature, water and light), aiming for clarifying research frameworks and methods in studies of LMA and providing guidance on future research.

Key words: leaf mass per area (LMA), leaf density, leaf thickness, photosynthesis, mesophyll conductance to CO2 (gm), environmental stress
