- Abstract
A hydroponic culture experiment was conducted to study the responses of 40 Chamaecrista varieties (lines) to 120 mg ∙ L-1 of Al3+, with the correlations between the relative tolerance values of various characters of different genotypes and the comprehensive evaluation coefficient compared. Among the characters of the genotypes, the relative plant height, relative root dry mass, relative shoot dry mass, and relative root activity could be selected as the important indices for screening the Al-tolerant genotype of Chamaecrista. In the test 40 Chamaecrista varieties (lines) , the 86134R2 , 2208 , 3170 , 316 , 2211 , and 2232 had stronger Al-tolerant capability , belonging to Al-tolerant genotype, whereas the 34721R1, 92985, and 3184 had weaker Al-tolerant capacity, belonging to Al-sensitive genotype.
