Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were described in the late 19th century from complex bud galls on Atriplex halimus in the Mediterranean Basin. In the present study Asphondylia punica is redescribed, A. ...
Shrubs of the Great Basin desert in Utah are subjected to a prolonged summer drought. One potential consequence of drought is a reduced water transport capability of the xylem. This is due to drought-induced cavitation. We used the centrifuge method to measure the vulnerability of root and stem xylem to cavitation in six native shrub species. The shrubs fall into three categories with regards t...

Phytoremediation potentials of four poplar lines, Populus nigra (N-SL clone), Populus canescens, and two transgenic P. canescens clones were investigated using in vitro leaf discs cultures. The transgenic poplars overexpressed a bacterial gene encoding gamma-glutamylcysteine synthetase in the cytosol (11ggs) or in the chlopoplasts (6LgI), and therefore, they contained an elevated level of gluta...
The efficiency of livestock production in shortgrass steppe may be increased by grazing fourwing saltbush (Atriplex canescens [Pursh] Nutt)-dominated rangeland in late fall and/or early spring, but there is a paucity of information concerning stocking rates and animal gains. The objective of this study was to compare the effects of light and moderate stocking rates on weight gains of heifers gr...
چکیده در تحقیق حاضر تکنیک های شکست خواب بذر در پنج گونه از جنس atriplexمتعلق به تیره chenopodiaceae مورد بررسی قرار گرفت. دو گونه atriplex leucoclada و a. verrucifera از هالوفیتهای بومی ایران می باشند ولی گونه های a. canescens، a .halimus، a .lentiformis وارداتی بوده و برای اصلاح مناطق خشک و نیمه خشک ایران کشت می شوند. نتایج تحقیق حاضر نشان داد برخلاف a. lentiformis، گونه های a. canescens، a....
