Traits related with tolerance to excess boron in wheat

Abstract

Excess boron can limit the plant growth and yield, particularly in and and semiarid environments. Sixty wheat genotypes were included in the trial in order to investigate the relationship among traits related to tolerance to excess boron and to determine the most informative treatment. Root length, dry weight and boron content were measured at seedling stage. Genotypes with small root growth Suppression on treatments, namely boron tolerant genotypes, generally had smaller dry weight reduction and lower boron content. Positive correlations among diverse boron treatments were found for all studied traits; therefore, any analysed treatment may be informative enough for further research.
