20.500.12556/DiRROS-7636 Genetski vidik naravne obnove smrekovega sestoja na nastali raziskovalni ploskvi Šijec na Pokljuki The genetic aspect of the spruce stand natural regeneration in the permanentforest research plot Šijec on the Pokljuka plateau Namen raziskave je bil preveriti sposobnost naravnega obnavljanja genetskega vira Picea abies (L.) Karst. na objektu stalne raziskovalne ploskve Šijec na Pokljuki, Slovenija. Genetsko strukturo zrelega sestoja smreke in genetsko strukturo naravnega mladja v razlino velikih pomladitvenih jedrih smo preuili z elektroforetsko analizo 15 polimorfnih izoencimskih genskih lokusov desetih encimskih sistemov (GDH, F-EST, GOT, IDH, LAP, MDH, PGI, PGM, SKDH, 6-PGDH). Pod doloenimi pogoji je bila genetska struktura 101 dreves naravnega pomladka in 64 dreves sestoja, iz katerega je nastal, popolnoma primerljiva. Obnova smrekovega sestoja z naravnim pomlajevanjem zagotavlja trajno ohranjanje genskega vira smreke in je v primeru vejih pomladitvenih jeder tudi zagotoviloza neprekinjeno ohranjanje njegove prilagoditvene sposobnosti. The aim of the research was to check the ability of natural regeneration for sustainable conservation of Picea abies (L.) Karst. genetic resource in the permanent forest research plot Šijec on the Pokljuka plateau, Slovenia. The genetic structures of spruce stand and its natural regeneration centres of different size have been studied by means of electrophoretic analysis of ten enzyme systems (GDH, F-EST, GOT, IDH, LAP, MDH, PGI, PGM, SKDH, 6-PGDH) for 15polymorphic isozyme gene loci. Under certain conditions, the genetic structures of 64 adult mother trees of the basic stand compared to 101 young spruce trees from the regeneration centres included in the study were closely similar. The regeneration of spruce stand by natural regeneration permanently conserves the spruce genetic resource and is, in the case of bigger regeneration centres, also an assurance of its continuous adaptability.
