Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Foreliggende rapport er en utredning av konsekvensene for reindriftsnæringen ved etablering av ny 132 kV kraftlinje på strekningen Leirosen – Meisfjord i Leirfjord kommune. Både planområdet og influensområdet har «stor verdi» for Røssåga/Toven reinbeitedistrikt. Samlet belastning for Røssåga/Toven reinbeitedistrikt er stor, og ethvert nytt inngrep vil redusere fleksibiliteten til distriktet. I anleggsperioden vurderes det at påvirkningen på reinen fører til at området blir «sterkt forringet». I driftsfasen er det vurderingen av mulig visuell påvirkning på reinen fra kraftlinja som fører til at influensområdet blir «noe forringet». Dette gir konsekvensgrad «-» (inkludert samlet belastning). Det er foreslått skadereduserende tiltak som er vurdert at reduserer de negative konsekvensene nok til å sikre framtidig drift i Røssåga/Toven reinbeitedistrikt.

European fruit research institute network (EUFRIN) has started coordinated apple rootstock trials across the Europe in 2017. Until now, nineteen research institutions from 14 countries established 6 apple rootstock trials where 33 apple rootstocks of different vigour are in tests. Introduction of new apple orchard designs, multileader canopies usually require more vigorous rootstocks. Investigations of semi-dwarfing apple rootstocks ‘PFR1’ and ‘PFR3’ (New Zealand), ‘G.935’ and ‘G.202’ (US), ‘EM_01’ (UK) and ‘G.11’ as control were performed with apple ‘Galaval’ in Spain, France, and Lithuania during 2017-2023. On the average of five trial sites, the most vigorous trees were on ‘EM_01’, ‘PFR1’ and ‘PFR3’, exceeding vigour of trees on ‘G.11’ by 61 – 84%. Apple trees on rootstocks ‘PFR1’, ‘PFR3’ and ‘G.935’ produced higher cumulative yields, ‘G.202’ similar and ‘EM_01’ significantly lower yield comparing with ‘G.11’. Fertility index of ‘G.935’ equalled fertility of dwarfing ‘G.11’. Fertility index of ‘PFR3’ was similar to ‘G.202’, and the lowest was recorded for ‘EM_01’. Average fruit size did not depend on rootstocks. Rootstock – site interaction was not significant for tree vigour, fruit size, however significant interactions were recorded for cumulative yield and fertility index.

European fruit research institute network (EUFRIN) has started coordinated apple and pear rootstock trials across the Europe in 2017. First pear rootstock trial was established in 2019 where quince rootstocks from NIAB (UK) breeding program ‘QR196-9’ and ‘QR530-11’ were compared with rootstocks ‘Adams’ and ‘Sydo’. Investigations were conducted with pear cultivar ‘Conference’ in Spain, Romania, Poland and Norway during 2019-2023. In all sites the most vigorous pear trees grew on ‘QR196-9’ rootstock. On the average of four trial sites, the weakest growth was recorded on ‘QR530-11’, except the Spanish site. Pear trees on rootstock ‘Adams’ produced the highest cumulative yields. Cumulative yields on other rootstocks were significantly lower by 16-23% without significant differences between them. However, site geographical position, climate and soil properties had a significant effect on rootstock performance. Similar to trees on ‘Adams’ high pear yield in Spain was harvested from trees on ‘QR196-9’; on ‘QR530-11’ rootstock in Poland, but ‘Sydo’ and ‘QR530-11’ rootstocks gave the highest yield in Romania. On the average of all sites, the least cumulative fertility index was recorded on ‘QR196-9’. Significant rootstock site interactions were revealed: rootstock ‘Adams’ had the highest cumulative fertility index in Spain and Norway, while rootstock ‘QR530-11’ in Poland and Romania.
