BACKGROUND Water influences various physiological and ecological processes of plants in different ecosystems, especially in desert ecosystems. The purpose of this study is to investigate the response of physiological and morphological acclimation of two shrubs Haloxylon ammodendron and Calligonum mongolicunl to variations in irrigation intervals. METHODOLOGY/PRINCIPAL FINDINGS The irrigation ...

The effect of mesoporous titanium dioxide nanoparticles on germination traits black saxaul seeds (Haloxylon aphyllum (Minkw.) Iljin) under drought stress

gauge instrument or prism was introduced, which significantly expedited the process. There was no national forest resource information in China during 1963–1972. The first NFI was performed during 1973–1976, in which a stratified systematic sampling technique was used to locate NFI sample plots. Each province, autonomous region, or municipal city designed one or more sampling populations accord...

Mathematical model describing energetic efficiency (defined as a ratio of energy obtained in the form of biofuel to the sum of energy inputs necessary to facilitate production) of agricultural subsystem as a function of technological parameters was developed. Production technology is characterized by parameters of machinery, topological characteristics of the plantation as well as transportatio...

There are six species in the genus Chamaecyparis worldwide, of which two, namely the Hinoki cypress (Chamaecyparis obtusa Sieb. et Zucc.) and Sawara cypress (Chamaecyparis pisifera Sieb. et Zucc.) are distributed in Japan (Maruyama et al., 2002). The Hinoki cypress is one of the most important commercial timber trees in Japan, representing about 25% of the plantation area in the country. Howeve...

This paper reports the result of the study in the AOE869 test site by exploring ASAR/APP dual polarization (VV, VH) image. The result is very promising, as it could differentiate clearly two land cover types : forest timber plantation and oil palm plantation. Although they play an important role for the monitoring of deforestation, these land covers were difficult to be differentiated in high r...

Increasing urbanisation and industrialisation have led to a dramatic reduction in forest area, and now only culturally protected remnants of natural forests and some new plantations remain in most areas of the north of Iran. To investigate the status of the chemical and physical characteristics of soil under these remnant forests and assess the possible impacts of reforestation on soil properti...
