Abstract

Abstract:

Populus euphratica with heteromorphic leaves plays an irreplaceable role in maintaining the ecological balance in the arid desert area of Northwest China. It is of great significance to study the relationship between branch and leaf morphology and biomass and to explore the strategy of resource allocation for P. euphratica. By measuring the morphological characters and biomass of annual branches and leaves of male and female P. euphratica at different diameter classes， we studied the relationship between male and female branches and leaves of P. euphratica， at different development stages and canopy. The results showed that the number of leaves of male and female plants decreased， and the diameter of branches， petiole length， diameter of the petiole， leaf area， the number of leaves， branch dry weight， and dry weight increased with the increase of diameter class. Further analysis showed that there was an allometric relationship between the branch and leaf morphology of male and female P. euphratica with different diameter classes. The morphological transformation speed between branches and leaves was faster in males， while the biomass conversion efficiency between the branches and leaves was higher in females. Also， there was an allometric growth relationship between the branches and leaf morphology of male and female P. euphratica at different canopy heights. With the change in canopy height， the transformation speed between the branches and leaves of female plants was faster， while the biomass transformation efficiency of male plants was higher. There was an allometric growth relationship between male and female branches， leaf morphology， branch dry weight， leaf dry weight， and leaf morphology of P. euphratica in different diameter classes or different canopy layers. In the high canopy and mature development stages， P. euphratica may efficiently provide water and mineral elements for the leaves with large petiole length， the diameter of the petiole， and leaf area through shorter and thicker annual branches. It provides a theoretical basis for further understanding of the differences in environmental adaptability between male and female P. euphratica and the distribution of male and female in the future planting.

Key words: Populus euphratica, allometric growth, morphological characters, biomass, developmental stage
