Metabolic activities of eight oil palm progenies grown under aluminum toxicity

Abstract. Putra ETS, Purwanto BH, Wulandari C, Alam T. 2021. Metabolic activities of eight oil palm progenies grown under aluminum toxicity. Biodiversitas 22: 3146-3155. In Indonesia, is mostly cultivated on red-yellow podzolic soils, which mainly contain the high availability (Al). This condition might affect growth i.e stunted and root damage. Therefore, this study was aimed to characterize metabolic Al The conducted from January December 2018 in Bendosari Hamlet, Madurejo Village, Prambanan Sub-District, Sleman District, Province Yogyakarta, Indonesia. trial laid out a randomized complete block design (RCBD) factorial with three blocks as replications, experimental factors including concentration. observation concentration planting medium, activities, growth. data were analyzed using ANOVA, PLS-SEM, stepwise regression, hierarchical clustering heatmap, GGE-Biplot. results showed that Simalungun, Dumpy, Yangambi progeny could grow adapt better than other toxicity conditions. resistance poisoning mechanism shown by relatively low activity O2-, H2O2, MDA, REL, whereas SOD, POD, GB, AARed, ?-Toch, TPC RDW and, SDW higher relatively.
