Species competitive abilities and their distributions are closely related to functional traits such as biomass allocation patterns. When we consider how nutrient supply affects competitive abilities, quantifying the apparent and true plasticity in functional traits is important because the allometric relationships among traits are universal in plants. We propose to integrate the notion of allom...

The high quality and quantity seed production in old saxual shrubs are essential for regeneration and sustainable development of saxual forests in desert areas. The objective of this study was to determine the effects of different pruning height on saxual seed production. The study was carried out in an obviously wilted saxual forest located in Ashkezar desert in Yazd in 1994. The experiment wa...

soil is known as a suitable reservoir for carbon sequestration. the objective of this study was to investigate the capability of haloxylon on sequestration of carbon in sand dunes of yahya abad, sabzevar, in northeastern iran. eighty soil samples were taken from two depths of 0-5 and 5-10 cm under and between haloxylon trees. eight soil profiles under and between haloxylon trees were described ...

Haloxylon ammodendron (C.A.Mey) Bunge is one of the important species arid desert vegetation in China, and it also an ideal material for studying plant stress resistance, which plays extremely role protecting ecosystems preventing land desertification. However, there are relatively few studies on regeneration fusiform, genetic transformation system has not been successfully reported, restricts ...
