20.500.12556/RUL-142160 Vpliv podlage na vsebnost metabolitov v cepljeni sorti Influence of rootstock on metabolite content in grafted varieties V današnjih časih je na trgih povpraševanje po kakovostni hrani vedno večje. S pravilno izbiro podlage, ki se še vedno uporablja predvsem kot pomoč za razmnoževanje sort, bi lahko pridelovalci pridelali bolj zdravo in kakovostno hrano. Raziskave so pokazale, da imajo podlage vpliv tako na primarne kot tudi sekundarne metabolite v plodovih na njih cepljenih sort. Kolikšen je ta vpliv, je odvisno od podlage, sadne vrste in tudi sorte. Raziskava, v kateri so bile limone cepiljene na dve različni podlagi v kombinaciji s sedmimi vmesnimi debli, je pokazala, da na vsebnost flavonoidov bistveno bolj vpliva podlaga kakor pa vmesno deblo. Poskusi na agrumih so pokazali, da bujnejše podlage z boljšim sprejemom vode v rastlino zmanjšajo vsebnost sladkorjev in organskih kislin. Pri breskvah pa so se najbolje odrezale podlage, ki so hibridi breskve in mandlja. Ugotovili so tudi, da ima genotip podlage večji vpliv na vsebnost fenolov kakor bujnost ter da bi lahko v jabolkih s pravilno kombinacijo podlage s sorto dosegli stabilnejšo vsebnost le-teh, kljub spremenljivim vremenskim razmeram. Ni bilo ugotovljena nobena podlaga, ki bi bila najbolj optimalna za vse sorte iste sadne vrste, ampak so bile za različne sorte optimalne različne podlage. Kopičenje fenolov okoli cepljenega mesta pa bi lahko bil pokazatelj neskladnosti podlage in sorte. The demand for quality food in the markets is increasing nowadays. With the correct selection of the rootstock, which is still used mainly as an aid for the propagation of varieties, growers could produce healthier and better-quality food. Research has shown that rootstock has an impact on both primary and secondary metabolites. The extent of this influence depends on the rootstock, the fruit class and the variety. Research in which lemons were grafted onto two different rootstocks in combination with seven different interstock showed that the content of flavonoids is significantly more influenced by the rootstock than the interstock. Experiments on citrus fruits have shown that vigorous rootstocks with better water uptake into the plant reduce the content of sugars and organic acids. In research on peaches, peach and almond hybrids performed best along other rootstock. The results have also shown that the genotype of the rootstock has a greater influence on the phenol content than induced tree vigour and that a more stable concentration of these could be achieved in apples with the correct combination of the rootstock and the variety. No rootstock was found to be the most optimal for all variety of the same fruit species, but different rootstocks were optimal for different variety. Accumulation of phenols around the graft site could be an indication of incompatibility between the rootstock and the variety. podlaga sorta primarni metaboliti sekundarni metaboliti neskladnost rootstock variety primary metabolites secondary metabolites incompatibility true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2022-10-22 07:15:28 2022-10-22 07:15:35 2022-10-26 09:07:22 0000-00-00 00:00:00 2022 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 213866 127136515 28200.pdf 28200.pdf 1 67E486642BD66BDDDCBE6AF682E8E2B9 62f0a29adc3084005b8a27f885c15bfaa04cc36cf7090f8074729faf4f2096f7 7f70306e-51c8-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=163442 Biotehniška fakulteta 0 0 0
