20.500.12556/DKUM-73980 Spremljanje razvoja jagodnjaka (fragaria x ananassa duch.) v jesensko – zimskem času Development of the strawberry plant (fragaria x ananassa duch.) during the autumn – winter period V obdobju 2018/2019 smo v jesensko-zimskem času od septembra do januarja v nasadu jagod v Zrkovcih spremljali razvoj posameznih delov jagodnjaka (Fragaria x ananassa Duch.) sorte 'Clery'. Zanimala nas je dinamika razvoja posameznih delov jagodnjaka v obdobju, ko klimatske razmere ne omogočajo optimalnih pogojev za rast in rastline preidejo v obdobje zimskega mirovanja. Meritve smo izvedli v petih terminih, v vsakem terminu vzorčenja pa smo po sistemu naključnih blokov izbrali 9 rastlin jagodnjaka, jih izkopali in stehtali ter izmerili posamezne dele nadzemnih in podzemnih delov. Spremljali smo povprečno mesečno temperaturo zraka v obdobju izvajanja meritev in temperaturo tal na globini 15 cm na dan vzorčenja. Rezultati so pokazali, da je padec temperature tal s 3,6 °C na 0,2 °C spodbudil rast korenin, medtem ko je nadzemni del jagodnjaka z nižanjem povprečne temperature zraka skozi termine vzorčenja upočasnil rast. V obdobju od septembra do januarja so rastline jagodnjaka pridobivale na masi, vendar je bila do tretjega termina vzorčenja (26. 4. 2018) rast nadzemnega dela rastlin intenzivnejša, kasneje pa je nadzemni del rastline prešel v obdobje mirovanja in se je začela intenzivna rast korenin, ki so dosegle največjo povprečno maso (83,4 g) v zadnjem terminu vzorčenja v januarju. During the autumn-winter season of 2018/2019 – from September to January – we observed the development of the strawberry plants (Fragaria x ananassa Duch.), species 'Clery', in the strawberry plantation in Zrkovci. We were interested in the dynamics of the development of the individual parts of the plants in the period, when the climate does not allow optimal conditions for growth and the plants enter the period of winter stagnation. The measurements were performed five times. Each time we coincidentally chose 9 strawberry plants, dug them out, weighted them and measured their above and below ground parts. We followed the monthly average air temperature during our measurements and the soil temperature 15 centimetres below the ground on the day of the measurement. The results showed that the fall in temperature of the soil from 3,6 °C to 0,2 °C encouraged the root growth, while the fall in temperature of air during the measurements resulted in slower growth of the above ground parts of the plants. From September to January the plants were gaining their mass, but the growth of the above ground parts of the plants was more intense until the third term of the sampling (26. 4. 2018). Later the above ground parts entered the period of stagnation and the root growth became more intense. They reached the biggest average mass (83,4 g) in the last term of sampling in January. jagodnjak dinamika rasti razvoj koreninski sistem temperatura strawberry plants the growth dynamics development root system temperature true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-07-11 13:31:32 2019-07-18 10:07:11 2022-08-09 07:56:11 2019-07-26 11:55:53 2019 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:BSB382HJ UN_Lobnik_Mitja_2019.pdf UN_Lobnik_Mitja_2019.pdf 1 51494D54886BB81D4373E1E2D3EBA183 6400268502d4cce204b6b99bad2412eadad7549172ca9140392dfff2e1f66826 c9d1294b-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/b10d47cc-f93b-4283-baf9-287efd09f9a5 https://dk.um.si/Dokument.php?lang=slv&id=135262 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
