Istraživanja su obavljena u pokusnom voćnjaku Sadjarskog centra Maribor-Gačnik sa sortama Elstar i Jonagold (2500 stabal/ha), te Idared i Golden Delicious (3000 stabala/ha), cijepljenim na podlozi ...M9, uzgajanim u obliku vitkog vretena. Pokus je trajao tri godine(3-5. godina poslije sadnje). Pokus je za svaku sortu postavljen u pet tretmana (fertirigacije s 45 kg N/ha, 120 kg N/ha, 60 kg N/ha, natapanje bez gnojiva i kontrola – bez gnojiva i vode), u dvije varijante (tretmani tijekom vegetacije od 1. svibnja do 20. lipnja varijanta A i tretmani od 1. svibnja do 1. kolovoza – varijanta B. Neovisno o primijenjenim tretmanima, tijekom dvije godine prirast debla bio je približno jednak kod sorti Idared i Golden Delicious, nešto veći kod sorte Jonagold, a najveći kod sorte Elstar. Najveća prosječna dužina jednogodišnjih izbojaka utvrđena je kod sorte Elstar, dok kod sorte Jonagols, koja po svojim osobinama spada u bujne sorte, prosječna dužina jednogodišnjih izbojaka nije bila bitno veća nego kod sorte Idared i Golden Delicious. U odnosu na ostale sorte, kod sorte Elstar utvrđen je značajno veći broj jednogodišnjih izbojaka, a najmanji kod sorte Idared. Istraživanja su pokazala da fetirigacija jabuke pojedinih sorti ima učinke različitog intenziteta na vegetativni rast. Dobiveni podaci potvrđuju poznatu činjenicu da su sorte Jonagold i Elstar bujnije od Idareda i Golden Deliciousa.
El interés que tienen los países con grandes riquezas naturales en la reducción de su deuda externa y el interés que tienen los países industrializados en la conservación de la naturaleza se pueden ...combinar mediante un canje de deuda externa por conservación de naturaleza (Debt-for-Nature Swaps swap (del inglés): cambio, canje). Existen dos esquemas para el canje: (I) Dos gobiernos, uno acreedor con interés en la protección de la naturaleza y otro deudor interesado en la disminución de la deuda externa, acuerdan la donación de la obligación a cambio de la conservación de la naturaleza. (II) Un banco comercial de un país desarrollado, acreedor de un país en desarrollo con dificultades en la cancelación de la deuda, vende en el mercado secundario títulos de esta deuda por un precio menor que el de su valor nominal, pues sólo así logra disminuir la pérdida ocasionada por la no cancelación de dicha deuda. Una organización no gubernamental ambiental internacional compra la deuda y negocia con el país deudor la forma de cancelarla. Los canjes de deuda externa por conservación de la naturaleza representan un valioso complemento de la ayuda para el desarrollo orientada hacia el medio ambiente otorgada por los países industrializados, que sin duda deben desembolsar la contribución decisiva para la protección de ls grandes riquezas naturales en los países en desarrollo.

The interest that countries with great natural wealth have in the reduction of external debt and the interest that industria- lized countries have in the conservation of the nature can be combined by means of an exchange of external debt for nature conservation. (Debt-for-Nature Swaps swap (from the English language): change, exchange). Two schemes for the exchange exist: (I) Two governments, one, a creditor, interested in nature preservation and another, the indebted one, interested in reducing external debt, decide to cancel the obligation in exchange for the conservation of the nature. (II) A commercial bank of a developed country, creditor of a developing country with difficulties in the cancellation of the debt, sells in the secondary market titles of this debt by a price smaller than that of its nominal value, because only in this manner can it manage to diminish the casualty inflicted by the noncancellation of this debt. An international environmental nongovernmental organization buys the debt and negotiates with the indebted country the manner in which the debt is to be cancelled. The exchanges of external debt for nature conservation represents a valuable complement to the aid for the development oriented towards the environment granted by the industrialized countries, that without a doubt must disburse the decisive contribution for the protection of the great natural wealth in developing countries.

La gestion et la valorisation des sédiments de dragage et de curage non-immergeables constituent des enjeux scientifiques et industriels majeurs auxquels la chaire industrielle de recherche " ...Économie Circulaire des Sédiments : EcoSed ", lancée en 2014 par l’IMT Lille Douai, vise à répondre à travers une approche pluridisciplinaire. Les travaux menés dans le cadre de cette thèse de doctorat s’inscrivent dans un contexte de recherche partenariale associant des producteurs de sédiments et des industriels. Ces travaux visent plus particulièrement (i) la mise en place d’une méthodologie de caractérisation de l’écotoxicité intrinsèque des sédiments dans la perspective de leur intégration dans les filières de valorisation ; (ii) l’application de la méthodologie multi-échelle de la démarche nationale "SEDIMATERIAUX" pour la démonstration de l’innocuité environnementale d’un sédiment marin utilisé dans un scénario de valorisation en voirie légère ; et (iii) la comparaison de la méthodologie nationale sur l’acceptabilité environnementale des matériaux alternatifs en technique routière avec celle proposée dans le cadre réglementaire européen sur les produits de construction. Ces travaux ont permis de proposer un protocole de préparation des matrices sédimentaires et une batterie de bioessais sensibles.L’évaluation environnementale des sédiments marins utilisés dans les différents scénarios de valorisation en génie civil (bétons pour voiries légères, assises routières, bétons compactés routiers) a permis de valider l’innocuité de ces matériaux et de mettre en évidence la bonne stabilisation des éléments traces métalliques et métalloïdes au sein de leur microstructure.
The management and beneficial reuse of non-immersible dredged sediments are major scientific and industrial issues. The industrial research chair " Circular Economy of Sediments: EcoSed ", launched in 2014 by IMT Lille Douai, aims at answering these issues through a multidisciplinary approach. As part of this Doctoral Thesis, investigations were carried out under a partnership research context by combining sediment managers and industrial partners. More specifically, this work aims at (i) to set up a methodological approach to measuring the intrinsic eco-toxicity of sediments prior to their beneficial reuse; (ii) to implement the multi-scale national approach “SEDIMATERIAUX” to check the environmental safety of marine dredged sediment used as aggregates in road concretes; (iii) to compare the national approach on the reuse of alternative materials in road engineering with the European framework developed for environmental assessment of construction products. The results of this work allowed to propose a preparation protocol for the sediment matrix and a sensitive battery of bioassays. Environmental assessment of marine sediments reuse in the field of civil engineering (road concrete, roadbed, roller compacted concrete) allowed validating the environmental safety of these materials and to highlight the achievement of the good trace elements stabilization through their microstructure.
