Abstract

Aluminum can have harmful effects on plant growth both directly and indirectly. This study aims to examine the tolerance level of lines of rice plants to aluminum stress in ultisol soil. This research was conducted from February 2020 to May 2020 in.the Experimental and Research Field of Faculty of Agriculture, Fisheries and Biology, Universitas Bangka Belitung. The experimental design used a Factorial Complete Randomized Design (FCRD) consisting of 2 factors. Factor 1 was 10 F6 rice lines and 2 check varieties. Factor 2 were P0 as control (0 ppm) and P1 as stress Al 200 ppm. The results showed that plant varieties had very significant effects on plant height, leaves number, productive tillers number, root length, panicle length, flowering age, harvest age, the weight of pithy seeds, and the number of pithy seeds, but no significant effect on the root volume. The application of 200 ppm aluminum does have not a significant difference with the control treatment (0 ppm aluminum) for all observed characters. Based on the results showed that all f6 rice lines tested had a score of 1 (tolerant) of aluminum stress in ultisol soil.
