| ABSTRACT: Salt stress is one of several major abiotic stresses that affect plant growth and development, and there are many evidences that silicon can ameliorate the injuries caused by high salinity. This study presents the results of an assay concerning: (1) the effect of in vitro NaCl-induced salt stress in cape gooseberry plants and (2) the possible mitigating effect of silicon in saline conditions. For that, nodal segments were inoculated in Murashige and Skoog (MS) medium under salinity (0.5 and 1.0% NaCl) with different silicic acid concentrations (0, 0.5 and 1.0g L-1). Phytotechnical characteristics, photosynthetic pigments content, and leaf anatomy were evaluated after 30 days. Shoot length, root length, number of leaves and buds, fresh and dry... |

| The small passerine Cyclaris gujanensis can tear into small pieces large or heavy-bodied preys that could not be swallowed whole such as frogs, snakes, bats and birds. However there are few studies on the cranial anatomy of this species. Thus, we focused on the description of the cranial osteology to contribute to the anatomical knowledge of this species and to make some assumptions about functional anatomy. The fossa temporalis is shallow but broad and the fossa of os palatinum is deepened. The os quadratum processes are long and thick. The os pterygoideum is enlarged and the upper jaw is strongly inclined ventrally (140°) with reference to the skull. The rostral extremity of rhamphotheca is hooked with ventral concavity to fit the mandible (pincer form).... |
