Amorpha fruticosa L. (Fabaceae), known as indigo bush, false indigo bush, false indigo and desert false indigo, is deciduous shrub (1-6 m tall). The woody weed species A. fruticosa has a high environmental adaptability and is present in different environmental conditions. In Vojvodina region (Northern Serbia), it is mostly present near irrigation channels and river banks, especially in alluvial or marshy areas. Since A. fruticosa is continually spreading near river banks, the aim of research was to determine seed bank composition near the Danube River. In 2014, soil sampling was performed at localities with high population of A. fruticosa (3-4 plants at age over two years and 10-14 plants at age 1-2 years). Soil samples were taken from two localities (Futog and Šangaj) with alluvial sandy soil and chernozem near the Danube River. Each sample was sieved through a system of copper sieves of various diameters. After the separation of seeds from samples, they were identified. Significant presence of A. fruticosa seeds (1,914 seeds/m²) was established in a layer of 0-10 cm. In the same soil layer, the significant presence of seeds of Stellaria media (L.) Vill. and Urtica dioica L. were also established. Seeds of A. fruticosa were not found in soil layers 10-20 cm and 20-30 cm. The invasive weed species A. fruticosa produces a large number of seeds in two cycles. The majority of the seeds stay in the upper soil layer, being dispersed by water (hydrochory).
This study presents research on the chemical composition of 15 horse chestnut seed genotypes (Aesculus hippocastanum L.) conducted on three different sites. The seeds were picked from selected trees in Bačka Palanka, Novi Sad and Sremski Karlovci at the end of September 2010. The statistical parameters point out the variables of the examined features of the seed. On the basis of the moisture, starch, fat and protein contents in the horse chestnut seeds, the genotypes, the reproductive material which would be used for the intensive production of the high grade seedlings for the greening of the different area categories in urban areas, are distinguished
In this paper are measured the changes in electrical output characteristics
of thin film solar panels as a function of external microclimate parameters.
Possible application of thin film solar panels in the production of
electricity on a small river boat was analyzed. Based on the results the
efficiency of thin film solar panels was determined. Also, cost benefit
analysis of their use on the river boat was performed as independent and
additional sources of electricity to the existing system which is based on
the ship diesel engine alternator.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
