Interactive effects of aluminum and iron on several soybean genotypes grown in nutrient solution

Abstract

The effects of combined stress of aluminum (Al) and iron (Fe) on plant root were studied using four soybean genotypes differing in Al+Fe tolerance in nutrient solutions. Those genotypes were selected based on their root length sensitivity index. The results showed that the root growth inhibition of Anjasmoro and Yellow Biloxi (Al-Fe tolerant genotypes) was 14.04%, less than Tanggamus and Lawit (Al-Fe sensitive genotypes) which was 60.38%. Anjasmoro and Yellow Biloxi accumulated less Al and Fe in root and shoot than Tanggamus and Lawit. © 2014 Asian Network for Scientific Information.
