After the Agricultural Settlement 2021, the scheme with subsidies for climate advice was established as a three-year pilot. NIBIO and Ruralis have carried out an evaluation of this pilot, conducting 18 in-depth interviews with farmers and climate advisors, and two surveys among Norwegian farmers. The results show that support and familiarity with the scheme has increased, but that a third of the farmers do not plan to use this. Subsidies is an important reason for farmers to apply for climate advice. Farmers are satisfied with the climate advice, perceiving it contributed to comprehensive knowledge and increased motivation to implement measures. Advisors state that to reduce skepticism, it is important to communicate that climate measures may have positive impact on farm economy and management without increasing workload or investments. Advisers describe lack of capacity as a barrier to increased use of the scheme. We find that the climate advice measure is expedient, recommending the subsidy to continue, as a voluntary scheme. The advisory capacity must be increased, including advisers from a broader range of productions, and that better and more targeted information about the scheme is required.

The fungus Neonectria ditissima causes fruit tree canker, a serious desease on apple and pear. In the past years the disease has become a threat for Swedish and Northern European apple production since devastating outbreaks destroy large numbers of trees. To date, no complete genetic resistance to N. ditissima is known in apple but genotypes (scion cultivars and rootstocks) differ greatly in their level of partial resistance. Furthermore, susceptibility of a scion cultivar may be influenced by the rootstock it is grafted to. Thus we aimed to improve our understanding of genetically determined differences in resistance among rootstocks and clarify cultivar/rootstock interactions with regards to canker resistance. For that, two experiments where conducted where differences in resistance were evaluated in 23 rootstocks (including two ‘M.9’ clones) and in the four most common scion cultivars in Swedish orchard grafted to four rootstocks differing in vigour (16 rootstock/scion combinations). The trees were inoculated in a greenhouse in artificially created wounds and the symptoms were assessed seven times every second week. In the experiment on rootstocks, significant differences (p=0.008). The new knowledge will be useful for growers, nurserymen and breeders.

The total phenolic content and antiradical activity in vitro varied significantly among the fruit mesocarps samples extracts of seven plum cultivars. It shows the influence of the cultivar factor on the quantitative composition of phenolic compounds and antiradical activity in vitro of P. domestica fruit mesocarps samples extracts. The highest total phenolic content and the strongest antiradical activ ity in vitro was determined in the fruit mesocarps samples extracts of the cultivar 'Čačanska Najbolja' (bred in Serbia). The fruit mesocarps from this cultivar could be valuable for the future researches – determination of the qualitative and quantitative composition of the individual phenolic compounds.

In the frame of EUFRIN apple rootstock trials, seven apple rootstocks are being tested for their resistance to ARD (apple replant disease) in several European countries. Current paper focus on the rootstock and soil type (ARD vs. fresh soil) effect on the accumulation of phenolic compounds in apple fruit. This research was performed at the Lithuanian trial site. Accumulation of phenolics compounds in fruit tissues was enhanced at replant soil. On the average of all rootstocks, total phenol content in fruit flesh increased by 25%, and in fruit peel by 31%. Hyperoside and rutin in fruit flesh and hyperoside, reynoutrin, phloridzin and procyanidin C1 were the most variable among detected phenolic compounds and their content in fruits from ARD soil was by 50 – 77 % higher than in fruits from the fresh soil. Content of (-) epicatechin in fruit flesh and (+) catechin and procyanidin B1 in fruit peel was similar in both ARD and fresh soil. Rootstock had a significant effect on the accumulation of phenolic compounds, but this effect was modified by soil conditions. Soil type had no effect on total phenol accumulation in fruits (flesh and peel) grown on Pajam 2 rootstock. Also, a stable phenol content in fruit flesh was on G.11 and M200 rootstocks, and in fruit peel on G.41. The highest increase of total phenol content at replant conditions was recorded on B.10 (by 66% in flesh and 60% in peel) and on G.935 (by 68% in flesh and 47% in peel) rootstocks.
