Boron tolerance in NS wheat lines
Tolerancija NS linija pšenice na visoke koncentracije bora
Апстракт
Boron is an essential micronutrient for higher plants. Present in excessive amounts boron becomes toxic and can limit plant growth and yield. Suppression of root growth is one of the symptoms of boron toxicity in wheat. This study was undertaken to investigate the response of 10 perspective NS lines of wheat to high concentrations of boron. Analysis of root growth was done on young plants, germinated and grown in the presence of different concentrations of boric acid (0, 50,100 and 150 mg/1). Significant differences occurred between analyzed genotypes and treatments regarding root length. Average suppression of root growth was between 11,6 and 34,2%, for line NS 252/02 are even noted 61,4% longer roots at treatments in relation to the control. Lines with mean suppression of root growth less than 20% (NS 101/02, NS 138/01, NS 53/03 and NS 73/02) may be considered as boron tolerant. Spearmans coefficients showed high level of agreement regarding rang of root length for genotypes treated ...with 100 and 150 mg H3BO3/l.
Ukoliko se mikroelemenat bor u zemljištu nalazi u prevelikoj količini postaje toksičan za više biljke. Supresija rasta korena je jedan od simptoma trovanja borom kod pšenice. Reakcija korenovog sistema 10 perspektivnih NS linija pšenice na visoke koncentracije bora utvrđena je naklijavanjem na filter papiru navlaženom rastvorima Н3ВО3 koncentracija 0,50,100 i 150 mg/l. Između ispitivanih genotipova i tretmana su zabeležene značajne razlike u pogledu dužine korena. Prosečna redukcija rasta korena se kretala od 11,6 do 34,2%, dok su za liniju NS 252/02 izmereni 61,4% duži koreni na tretmanima u odnosu na kontrolu. Linije kod kojih je prosečna redukcija rasta korena bila do 20% (NS 101/02, NS 138/01, NS 53/03 i NS 73/02) bi se mogle smatrati tolerantnim na bor. Spirmanovi koeficijenti su pokazali visok stepen saglasnosti ranga dužine korenova analiziranih genotipova na tretmanima 100 i 150 mgH3BO3/l.
