Descriptor: Aluminum tolerance (ALUMINUM TOLERANCE)



 
Definition:
Aluminum tolerance as expressed as P-value.(P-value is relative root growth as ratio of growth under Al stress to growth under no Al stress) between <.0001 and .05= highly sensitive, between .06 and.39= sensitive, .4 or higher = tolerant.

Distribution of Values for Aluminum tolerance (ALUMINUM TOLERANCE)

CodeDefinitionNumber of Accessions
1P-value 0.4 or higher, considered to be Al tolerant. Code based on P-values for comparing the levels of Al (control vs. 50M AlCl3) for each accession.14
2P-value between 0.06 and 0.39, PI considered to be Al sensitive. Code based on P-values for comparing the levels of Al (control vs. 50M AlCl3) for each accession.109
3P-value between <.0001 and 0.05, PI considered highly Al sensitive. Code based on P-values for comparing the levels of Al (control vs. 50M AlCl3) for each accession.197
