Astuti S.M. Yahya M.S. Hadi <p>Agricultural produce is commonly stored in warehouses after the harvest period, before being utilized and fulfilling the crop stock. However, crop threats are not only present during cultivation and harvest, but crops can also be infected during storage, which leads to agricultural loss. This research aimed to observe the resistance level of corn varieties of Bisma, Bisi 18, Bisi 19, Pioneer 21, Pioneer 29, and Pertiwi 3 to the <em>Sitophilus zeamaispest</em> of stored product insects. This resistance was based on the mechanism of non-preference (antixenosis) resistance, measured with the Free Choice Test Method (FCTM), and antibiosis resistance mechanism, measured with the No Choice Test Method (NCTM). The results showed that based on the susceptibility index (Dobie, 1974), corn varieties of Pertiwi 3 were categorized as resistant to <em>S. zeamais </em>pests, while the varieties of Bisi 19, Bisma, Bisi 18, Pioneer 21 and Pioneer 29 were moderately resistant.</p> 2019-06-12T11:39:41+02:00 ##submission.copyrightStatement## Evaluation of antidepressant-like effect Lavandulifolia stachys in the forced swimming test in comparison with imipramine and fluoxetine 2019-06-26T09:52:15+02:00 Shirali Kharamin Saeed Razmeh Mona Nabovvati Karim Moradian Samaneh Rahimi Maryam Orooji Laleh Taghavian Majid Kherad Mand Maher <p>Depression is a global problem associated with multiple social and health issues. In the present study, we analyzed the antidepressant effects of <em>Lavandulifolia stachys</em>, an herbal planton forced swimming test (FST). In this study, 36 rats were used. We gavaged the <em>aqueous extract of plant</em> (50, 100, 150 mg/kg), imipramine and fluoxetine (20 mg/kg) as standard antidepressant drug and normal saline for control group for a week. Then, their behavioral responses including climbing, swimming and immobility were recorded during the 5-min FST. Our experiments showed significant effects of <em>Lavandulifolia stachys</em> on swimming and immobility but not effect on climbing behaviors. Imipramine and fluoxetine increased climbing and swimming, respectively, and both reduced immobility, compared to saline control. Finally, our results show the extract of <em>Lavandulifolia stachys</em> could play an important role in treatment of depression like fluoxetine.</p> 2019-06-12T11:46:56+02:00 ##submission.copyrightStatement## Clonal integration of the invasive plant Wedelia trilobata (L.) Hitch in stress of flooding type combination 2019-06-14T11:47:15+02:00 Endang Saptiningsih Kumala Dewi S. Santosa Yekti A. Purwestri <p>The clonal invasion of <em>Wedelia trilobata</em> (L.) Hitchhas spread to riverside and edges of mangrove areas, which leads to the formation of flooding-stressed areas such as waterlogged and submergence. This study purpose to investigate the clonal integration mechanism of <em>W. trilobata</em> in stress of flooding type combination. This study was conducted in greenhouse with four combinations of flooding treatment on mother ramet (MR) and daughter ramet (DR) for 25 days. Several parameters were measured are shoot growth, relative growth rate (RGR), biomass, biomass allocation, adventitious root growth, and lenticel hypertrophy. The highest clonal performance was observed for the combination of field capacity (MR)-waterlogged( DR). The lowest performance was observed for the combination of waterlogged (MR)-submergence (DR). There were decreases in the shoot growth, RGR, and biomass allocation in mother ramet. However, adventitious root growth and lenticel hypertrophy increased in daughter ramet. The increase of flooding pressure suppresses the performance of clonal plants. Clonal integration buffered clonal plants by improving the performance of daughter ramet in the combination of flooding type. The clonal integration has facilitated <em>W. trilobata</em> invasion in inundated areas.</p> 2019-06-03T00:00:00+02:00 ##submission.copyrightStatement## Effect of two bottom fertilizers and previous crop on yield of durum wheat breeding seed (Triticum durum Desf.) 2019-06-26T09:52:13+02:00 Nadia Chiahi Louhichi Brinis <p>To improve the yield of durum wheat seed (<em>Triticum durum</em> Desf.), seven varieties were grown in an experimental field (Tifech region in Souk Ahras). The study focused on planting the varieties on two cropping precedents (sorghum and fallow grazing), in addition to the use of two bottom fertilizers, one potassic (Fosfactyl) and the other phoshonitrogen, (DAP). The analysis of the results showed a clear improvement in grain yields in the varieties harvested from the previous crop (Sorgho) and having received Fosfactyl as fertilizer. The best grain yields were displayed by the Carioca, Boussallem and Sersou varieties. After harvest, the study of soil parameters of the respective parcels showed soil with a sandy loam texture, with a low organic matter, with a slightly alkaline pH, while being low in salts.</p> 2019-06-14T10:01:31+02:00 ##submission.copyrightStatement## Conservation status and threats to vascular plant species endemic to Soutpansberg Mountain range in Limpopo Province, South Africa 2019-06-26T09:52:11+02:00 Ikarabeng Moraswi Samuel Oloruntoba Bamigboye Milingoni Peter Tshisikhawe <p>Soutpansberg Mountain range is one of the main biodiversity hotspots in South Africa and it is located in Limpopo Province. It possesses high diversity of flora and fauna. Communities surrounding this mountain have long benefited from the ecosystem services that the area provides. It is of importance to determine the threat status of plant species endemic to this mountain range that has been a great source of ecosystem services. Twenty-two endemic vascular plant species of the mountain range have been identified. In this study we use the South African National Biodiversity Institute (SANBI) current 2017 version Red List categories to determine the threat status of plant species endemic to Soutpansberg Mountain range. SANBI is the national body in South African that is responsible for national threat assessment for plant and animal species and they also provide data to IUCN (International Union ofC onservation of Nature) on threat status of plant and animal taxa found in South Africa. We calculated the categorical percentages of threat status of endemic vascular plants species of Soutpansberg Mountain range and the threats these plant species are facing were gotten from SANBI Red List. This study showed that over 50% of the plant species endemic to this area are of conservation concern meaning they deserve conservation attention. Majority of threats are due to anthropogenic pressure. This implies that the endemic flora of this region is facing risk of extinction. This study recommends protection of all the endemic plant species of this mountain range in order to prevent theirf uture extinction.</p> 2019-06-14T11:52:11+02:00 ##submission.copyrightStatement##
