Seed gal nematode (Anguina tritici Stein.) has not been reported as a parasite of wheat and barley in Bulgaria for more than thirteen years. However, in 2012 it has been detected in two locations of southeastern Bulgaria. Regarding this, the aim of the present study was to focus on the nematode pathogenicity and its impact on wheat plants. In a laboratory experiments were tasted five varieties of wheat against A. tritici. None of them showed to be resistant to the nematode. Field experiment were carried out in infested farmer fields during the 2012/2013 growing season to evaluate the effect of seed gall nematode on grain yield. A. tritici severity corresponded both with a decrease in number of grain spike and with an increase of number of distorted and died spike. Nematode pathogenicity potential corresponded also with a decrease of grain weight spike and its affect on yield.

Summer field trip to Sfântu Gheorghe branch at Ilganii de Jos (Tulcea County, Romania): A naturalistic approach

Between July 29 and August 5 2013, near Ilganii de Jos village (part of ROSCI 0065 Danube Delta, Nufăru commune, Tulcea County), on the oldest Danube branch, Sfântu Gheorghe, a personal field trip took place. In order to complete the didactic collections with some new fresh material, both animal and vegetal samples were collected, photographed, preserved and brought back in Bucharest, at U.A.S.V.M. laboratories. With the aid of an entomological net, various terrestrial arthropods (adult and larval insects, opilionids and arachnids) were captured on plants. Many species of the local vascular flora were pressed and dried further in a herbarium. Some of the specimens were already arranged for the use of students in class, like a Decticus verrucivorus (Orthoptera, Tettigonidae) female ovipositor, unionid adductor muscles or water caltrop (Trapa natans, Lythraceae) seeds. Natural phenomenons as mimicry and camouflage were noticed for Hyla arborea/Xanthium italicum or Coreus marginatus/Rumex obtusifolius associations.

The study was conducted in a hunting reserve in northeastern areas, Albania, in animals and wild birds such as stock dove, partridges, turtledoves and boars. The Institute of Food Safety and Veterinary (IFSV) Tirana, Albania, conducted the test in 158 samples taken from animals and birds. In order to achieve the analytical procedure of isolation and identification of Salmonellas the Standard method (ISO) was used, whereas for the serological identification, antiserum salmonele were used according to the White-Kayffmann scheme. The latest was mainly used to determine the exact species that used salmonelare antisera, Kauffmann-White scheme. After checking, the total positive samples resulted 49.31%, from which the E. coli 20, or 12.6% and salmonella 29, or 18.4%. Positive samples from poultry meat resulted in E. coli 13.3% and salmonella 10%, positive samples of pork resulted in E. coli 5% and salmonella 25%. Positive samples of eggs: E. coli 11.1%, salmonella 22.1%. The results also show that the samples with higher positivity result were turtle eggs, and less positive were doves and quails. Tests were also conducted from stool samples the results show as follows: Birds E. coli 8% and salmonella 16%, whereas pork with E. coli 10% and salmonella 30%. From the examined samples 5 strains of Salmonella spp were isolated and identified, the larges affected was that in birds i.e stock dove, partridges, turtledoves. Due to this 4 types of Salmonela were isoleted and detected: Salmonella agony, Salmonella entertidis, Salmonella infantis, from birds and also one from boar Salmonella typhimurium.

Urban green space – environment and culture

Written by Augustina TRONAC, Elena NISTOR, Nicoleta SÂRBU

The paper aims to be an interdisciplinary approach to green spaces in Bucharest with special reference to the Cișmigiu Garden. It is divided into two parts: scientific, in which the existing data emphasize environmental, economic and social benefits, and literary, in which examples of representative writings highlight the aesthetic and cultural dimension of the green spaces.

Yield components at some hybrids of sunflower (Helianthus annuus L.) under drought conditions from South Romania

Published in AgroLife Scientific Journal, Vol. 2 Issue 2
Written by Viorel ION, Georgeta DICU, Adrian Gheorghe BĂȘA, Daniel STATE

Sunflower (Helianthus annuus L.) is the most important oil crop in Romania. The grain yield is determined by the yield components, respectively those elements participating to the yield formation, such as: plant population (number of plants per hectare), head diameter (cm), number of grains per head, grain weight per head (g), weight of thousand seeds (g). Water deficit is considered to be an important yield-limiting factor of sunflower. However, sunflower is considered to be a crop well adapted to drought conditions, better adapted than maize. The aim of the paper was to present the results regarding yield components and grain yield obtained at an assortment of Romanian sunflower hybrids studied under drought conditions from South Romania. Also, it was aimed to evaluate the impact of drought on the sunflower yield components and grain yield compared to those values obtained under favourable conditions. The study was realised under field conditions in the year 2012, which was characterised as being a drought year. Researches were performed at an assortment of ten sunflower hybrids created in Romania, respectively: PRO 112, PRO 111, PF 100, PRO 229, PRO 121, PRO 122, PRO 131, PRO 132, PRO 141, and PRO 142. The study was implemented in three different locations in South Romania. Under drought conditions of 2012, the most affected yield component at the studied sunflower hybrids was head diameter. Compared to values obtained in favourable climatic conditions, in average for the studied sunflower hybrids the grain yield represented 70.0%. Under the same conditions, in average for ten maize hybrids, the grain yield represented only 37.8% from the values obtained under favourable climatic conditions. This is showing that sunflower is a better adapted crop to water stress than maize.
