Linking structural traits, non-structural carbohydrates and tree ecological strategies in different climates

Abstract:

Functional traits which impact plant fitness indirectly via their effects on growth, reproduction and survival are considered the widely accepted tool for studying the plant strategies. As an important functional trait, non-structural carbohydrates (NSC) are considered as indicator of balance between carbon sources and sinks in plants and reflect the adaptive strategies of plants. In xylem, NSC are mostly stored as soluble sugars and starch in radial and axial parenchyma (RAP). The design of the xylem space of woody plant species also plays important roles in tree growth and multiple functions including water transport, mechanical integrity and carbohydrate storage. However, little is known about how NSC impacts xylem multi-functionality, nor how the relationship between NSC and parenchyma fractions vary among species and climates. Whether NSC content in different organs coordinates with traits linked to the economic spectrum, that design plant ecological strategies, is still less known. In this seminar I will present how NSC and xylem traits are linked to tree physiological processes and ecological strategies and explore the trade-off of xylem structure and function, especially across a broad range of species and climates.
