Atriplex spp. (Atriplex canescens, A. lentiformis and A. halimus) plantation has been extensively used to reclaim rangeland in Iran for the past several decades. However, the impacts of this practice have been controversial. Due to the increasing adoption of this reclamation technique for degraded rangelands, it is important to investigate its impacts. The aim of this study was to investigate t...

this experiment aimed to investigate the effect of (zero, 20, 40 and 60 mg/kg atriplex forage) malva sylvestris on digestibility and microbial fermentation of atriplex in one-humped camel. fermentation parameters by gas production technique and in vitro digestibility by two-stage digestion were measured by two years old female fistulated camels. addition 40 and 60 mg/kg malva sylvestris increas...

Alongside Clem Tisdell’s prodigious scholarship, colleagues appreciate a quality he displays which characterises both economists and natural scientists. He sees the oddities in things – their incongruities, underside, gaps. Perusing the literature on regional and town planning, then, Professor Tisdell would notice articles with titles like the present one [1] and others suggesting uncertainty o...

Four new triterpenoid saponins, 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)-11alpha-methoxy-23-hydroxylongispinogenin, 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)-11alpha-methoxy-23,29-dihydroxylongispinogenin, 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)-29-hydroxysaikogenin F and 3-O-([beta-D-glucopyranosyl-(1-->2)]-beta-D-galactopyranosyl)...

Plant hydraulic characteristics were studied in diploid, tetraploid and hexaploid cytotypes of Atriplex canescens (Chenopodiaceae) to investigate the potential physiological basis underlying the intraspecific habitat differentiation among plants of different ploidy levels. Populations of A. canescens from different habitats of the Chihuahuan Desert (New Mexico, USA) were analyzed using flow cyt...

Plant productivity is limited by salinity stress, both in natural and agricultural systems. Identification of salt stress-related genes from halophyte can provide insights into mechanisms of salt stress tolerance in plants. Atriplex canescens is a xero-halophyte that exhibits optimum growth in the presence of 400 mM NaCl. A cDNA library derived from highly salt-treated A. canescens plants was c...

Increasing salinity led to substantially higher ratios of mesophyll surface area to leaf area (A(mes)/A) for Phaseolus vulgaris and Gossypium hirsutum and a smaller increase for Atriplex patula, a salt-tolerant species. The increase in internal surface for CO(2) absorption did not lead to higher CO(2) uptake rates, since the CO(2) resistance expressed on the basis of mesophyll cell wall area (r...
