nustatytas penetrometru IDP-500, audiniø tvirtumas – penetrometru FT 327. Ið kiekvieno varianto imta po 10 vaisiø, tvirtumas matuotas prieðingose vaisiaus pusëse. Vaisiø elektrocheminiai tyrimai atlikti LÞÛU Aplinkotyros laboratorijoje. Vandenilio jonø koncentracija nustatyta tiesioginës potenciometrijos metodu, matuojant jonometru Methrom AG CH -9101, redokso potencialas (rH vertë) nustatytas tiesioginës potenciometrijos metodu, matuojant jonometru Methrom AG CH –9101, naudojant platinos elektrodà, savitasis elektrinis laidis (rho vertë) matuotas konduktometru intoLAB WTW. Iðvestinio dydþio P vertë, charakterizuojanti produkto energinæ vertæ, apskaièiuota pagal NERST-o lygtá: P[µW] = [29,07 (rH-2pH)] 2 x rho -1 Rezultatai. Tyrimo metais abiejø variantø derlius akivaizdþiai didëjo, nes tyrimas pradëtas antraisiais po sodo pasodinimo metais. Pirmøjø ir antrøjø derëjimo metø duomenimis, obelø veislës ’Elise’ derëjimo dinamikos skirtumai, taikant skirtingo ûkininkavimo sistemas, neesminiai. 2005 metais ekologinës gamybos variante gautas 5 proc. didesnis derlius (1 pav.). 1 pav.
