Studies on Differential Response of Spring Canola Cultivars to Boron Toxicity.

This experiment was carried out at Central Anatolia, Turkey from 2002 to 2003, to determine genotypic range in B efficiency of eight spring canola cultivars, to identify the B-inefficient cultivars and to identify specific responses. The cultivars were grown under B moderate deficiency (extractable B 0.56 mg kg-1) and toxic B applied (15 kg B ha-1) conditions. According to the results, seed yield varied significantly among the cultivars and B application decreased the seed yield by 31% on average. Also, toxic B application reduced protein and oil contents similar to seed yield, and increased leaf B concentration in all varieties. This study has shown that leaf B concentration has increased considerably when B is applied to Pactol and Star cultivars, but seed yield of +B and -B has not shown significantly a change. It is possible to say that Star and Pactolwhich have not been affected by the toxic B applicationare genotypes that are tolerant to B toxicity and may be cultivated at B toxic lands.en10.1080/01904161003763740info:eu-repo/semantics/openAccessboron toxicityinteractionoil ratioprotein ratioseed yieldcanolaArticle33811411154Q2WOS:000277724500004Q3
