Abstract
The use of aluminum-tolerant upland rice varieties is an effort that can be made to utilize ultisol land. The application of water culture techniques in greenhouses can be an alternative method in the testing of plant tolerances. This study aims to examine the tolerance level of F8 upland rice lines to aluminum stress through low-pH water cultures. The method used is the Randomized Block Design with Split Plot pattern. The Concentration of Al as the main plot and genotypes of upland rice as subplot. The main plot treatment consists of 2 levels of treatment, i.e. 0 mg kg-1 and 60 mg kg-1 Al concentrations. The treatment of the subplot is consisting of 5 F8 upland rice promising lines and 3 varieties as comparison. Concentration of Al 60 mg kg-1 is likely to inhibit the growth of upland rice lines. Lines 19I-06-09-23-03 and 23A-56-20-07-20 are moderate based on the sensitivity index of stress and anatomy of the roots, while 21B-57-21-21-23, 23F-04-10-18-18 and 23A-56-22-20-05 are sensitive to aluminum stress in water culture media. Line of 19I-06-09-23-03 is a promising line with the best growth in aluminum concentrartion of 60 mg kg-1.
