Recently,
boron (B+) toxicity has received a great deal of
attention as it decreases yield of crops significantly. In
this study, we investigated whether the application of
different levels calcium (Ca2+) could alleviate B+
toxicity in Durum wheat induced by high levels of B+
present in irrigation water. Durum wheat cv. Ege-88 was
grown in soil culture with four levels of B+ (0,
2.5, 5 and 10 mg kg-1 soil as HBO3)
and three levels of calcium (0, 100 and 200 mg kg-1
as CaOH). B+ and Ca2+ applications
increased shoots concentrations of these nutrients in a
linear fashion, while increased Ca2+ application
reduced B+ concentrations in the shoots.
According to the analysis results, increased B
concentrations were decreased while Ca concentrations
increased dry matter in shoot. These results suggest that
liming has potential to alleviate B+ toxicity and
improve crop yield in Durum wheat.
Key
words:
Boron, boron toxicity, calcium, Durum wheat.
