Abstract

Bengkalis has various soil types, one of them is acid soil. The major problem in acid soil is aluminium toxicity that can harm rice plant roots. The objective of this study was to identify sticky chromosomes in some local rice genotypes from Desa Bantan Air, Bengkalis, Riau Province grown in Al stress medium. Plant materials examined were four local rice genotypes from the Desa Bantan Air, i.e. Amat Candu, Sadani, Solok, and Yamin. All of the rice genotypes were exposed to 12 ppm Al for 72 hours in minimum nutrient culture, pH 4. Each treatment was repeated three times. Randomized Block Design was used in this research. The results showed that sticky choromosomes were only detected at Yamin genotype treated by 12 ppm Al. It concluded that the sticky chromosomes found in the local rice genotypes from Bengkalis was Yamin genotype

Abstract

The major problem in acid soils is aluminium toxicity that can harm the rice plant roots. The objective of this study is to identify of Al-tolerant local rice genotypes from Bengkalis, Riau Province. Plant materials tested were four local rice genotypes from Desa Bantan Air, Kecamatan Bantan, Kabupaten Bengkalis, Riau Province, i.e., Amat Candu, Sadani, Solok, dan Yamin. Grogol variety was used as an Al-tolerant rice variety, while IR64 variety was used as an Al-sensitive rice variety. All genotypes/varieties were exposed to 12 ppm Al for 72 hours in nutrient culture, pH 4. Each treatment was repeated three times. Ten seedlings per genotype/variety were tested. Randomized Block Design was used in this research. The results showed that Yamin had the smallest PPA value (67%), followed by Grogol and Sadani (70%), Amat Candu (71%), Solok (72%), and IR64 (80%). Grogol and Sadani had same value of PPA and PAR, which demonstrated that both rice genotypes were tolerance to Al stress. It concluded that there were two Al-tolerant local rice genotypes from Bengkalis, such as Sadani and Yamin, while two others were Al-moderate, such as Amat Candu and Solok.
