Influence od storage duration on primary root and germ lenght of sunflower hybrid seed

Dorađeno sjeme (nezaprašeno) hibrida suncokreta Fakir, Orion i Apolon skladišteno je 36 mjeseci u dvoslojnim papir vrećama, u podnom betonskom skladištu s termoizolacijom (relativna vlaga zraka 55-60% i temperatura 10-12°C). Analiza istraživanih svojstava (dužina primarnog korijena i klice) bila je na početku skladištenja i nakon svakih 12 mjeseci skladištenja tijekom tri godine istraživanja. Rezultati istraživanja su pokazali da sjeme hibrida Fakir ima duži primarni korijen i klicu (0.3-0.6 cm i 0.3-0.7 cm) od Oriona i Apolona na početku i na kraju skladištenja. Hibrid Apolon ima najkraći primarni korijen i klicu (5.4 cm i 2.2 cm) na početku, kao i na kraju skladištenja (4.3 cm i 1.6 cm). Kod svih hibrida najveće smanjenje dužine primarnog korijena i klice bilo je poslije 36 mjeseca skladištenja. Dobivene razlike su statistički vrlo značajne za sva istraživana svojstva (hibrid, dužina skladištenja, interakcija hibrid x dužina skladištenja).After seed processing, sunflower seed Fakir, Orion and Apolon has been storage for 36 months. Seed samples were packed in two film paper bag and storage in two different storage. Concrete floor and storage with termoizolation (relative air humidity 55-60 % and air temperature 10 °C – 12 °C). In the time of storage, every 12 months, seed samples was getting and seed properties has been analyzed. After 36 months, primary root and germ length were measured. Results of this investigations approved, that Fakir hybrid seed has higher on primary root and germ length in accordance with Orion and Apolon. It was conclude that decreasing of primary root and germ length depend on hybrid and storage duration. Apolon hybrid had the largest decreasing of primary root (1.1cm) and germ length (0.6cm). Fakir hybrid had the smallest decreasing. Each hybrids in this investigations had the largest decreasing of primary root and germ length after 24 months of storage. Hybrid and storage duration, statistically very significant influence on seed quality decreasing

GTI-space : the space of generalized topological indices

A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way. Thisapproach defines a GTI-space from which both simple and composite TIs represent particular subspaces. Accordingly, simple TIs such as Wiener, Balaban, Zagreb, Harary and Randićconnectivity indices are expressed by means of the same GTI representation introduced for composite TIs such as hyper-Wiener, molecular topological index (MTI), Gutman index andreverse MTI. Using GTI-space approach we easily identify mathematical relations between some composite and simple indices, such as the relationship between hyper-Wiener and Wiener index and the relation between MTI and first Zagreb index. The relation of the GTI space with the sub-structural cluster expansion of property/activity is also analysed and some routes for the applications of this approach to QSPR/QSAR are also given

Incorporating stakeholders’ preferences into a multi-criteria framework for planning large-scale Nature-Based Solutions

Hydro-meteorological risks are a growing issue for societies, economies and environments around the world. An effective, sustainable response to such risks and their future uncertainty requires a paradigm shift in our research and practical efforts. In this respect, Nature-Based Solutions (NBSs) offer the potential to achieve a more effective and flexible response to hydro-meteorological risks while also enhancing human well-being and biodiversity. The present paper describes a new methodology that incorporates stakeholders’ preferences into a multi-criteria analysis framework, as part of a tool for selecting risk mitigation measures. The methodology has been applied to Tamnava river basin in Serbia and Nangang river basin in Taiwan within the EC-funded RECONECT project. The results highlight the importance of involving stakeholders in the early stages of projects in order to achieve successful implementation of NBSs. The methodology can assist decision-makers in formulating desirable benefits and co-benefits and can enable a systematic and transparent NBSs planning process
