20.500.12556/RUL-137827 Pot and ridge production of three highbush blueberry (Vaccinium corymbosum L.) cultivars under high tunnels In recent years, new approaches to intensive blueberry (Vaccinium corymbosum L.) production have become necessary, in terms of protected environments and planting systems. These are designed to avoid numerous production difficulties, such as market saturation, damage from hailstorms, bird attacks, and spring frosts, and specific soil property requirements. Use of high tunnels and planting in a custom substrate (e.g., pots, along ridges) have gained interest among growers in recent years. As in our previous study, we determined the performance of three blueberry cultivars, ‘Duke’, ‘Aurora’, and ‘Brigitta’, when planted in pots and along a ridge under a high tunnel. Substrate water content was maintained at the same level for the pots and the ridge, although the substrate temperature fluctuations were greater for pots. Plant growth in pots was significantly lower for ‘Duke’ and ‘Aurora’ compared to the ridge. Additionally, for ‘Aurora’, the fruit yield was significantly lower for pots (103.4 g/plant), compared to the ridge (315.2 g/plant), although the opposite was seen for ‘Brigitta’ (122.4 vs. 93.5 g/plant, respectively). Individual sugar and organic acid contents mostly coincided with total contents, with lower total sugars for ‘Duke’ and higher total organic acids for ‘Aurora’ and ‘Brigitta’ for pots. For ‘Duke’ and ‘Brigitta’ fruit, the contents of some individual phenolics showed significant differences between treatments for phenolic acids and flavonols. These data show that growth in pots can be a useful planting method for the blueberry cultivars ‘Duke’ and ‘Brigitta’, and high yields and good fruit quality can be attained by following correct technological measures. blueberry substrate water content substrate temperature plant volume yield fruit quality Vaccinium corymbosum ameriška borovnica vsebnost vode v substratu substrat temperatura substrata pridelek kakovost pridelka true false true Angleški jezik Slovenski jezik Članek v reviji 2022-07-01 13:56:01 2022-07-01 13:56:02 2022-09-15 04:15:53 0000-00-00 00:00:00 2022 0 0 14 str. iss. 4, art. 438 Vol. 12 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634.1/.7 2077-0472 10.3390/agriculture12040438 113557251 agriculture-12-00438.pdf agriculture-12-00438.pdf 1 109D4D3280921CDEC49CFC3AB9615F7B 8848fa3046e9e25c518244d6016bbb97e500dc97af8ff72103ae64f975ee896b 24abe38f-f936-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157925 https://www.mdpi.com/2077-0472/12/4/438 1 9311dd1d-f934-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157922 Biotehniška fakulteta 0 0 0
