Coordination of leaf economics traits within the family of the world's fastest growing plants (Lemnaceae)

چکیده
The duckweed family (Lemnaceae) is a group of free-floating aquatic plants with bodies consisting single floating fronds that multiply clonally. Although they are known to have the fastest relative growth rate (RGR) among higher plants, their functional trait coordination in relation within-family variation RGR poorly understood. We tested how species fit within covariation patterns as world-wide leaf economics spectrum (LES). To this end, several traits were evaluated for 15 species, and compared those global database plant traits. As group, duckweeds exhibited most acquisitive suite traits, extremely small mass per area (LMA), short life span high mass-based photosynthetic (Amass). These LES showed tight correlation RGR, corroborating our hypothesis resource underpins RGR. However, unlike other LMA weak association Amass family. also found unique positive between area-based rates, an indication represents different significance typical plants. Synthesis. Duckweeds, world's growing mostly follow locate at its extreme end. slight deviation from highlights experience some physical chemical constraints not faced by
