Boron tolerance in wheat roots

Abstract

One of the consequences of high boron concentrations in soil is the suppression of wheat (Triticum aestivum L.) roots growth. Variability of boron tolerance in wheat genotypes was analysed by germination on filter paper soaked with different concentrations of boric acid (0, 50, 100, 150 mg/l). Observed genotypes showed significant differences in roots length and number at different boron treatments. Genotypes which had very small differences in roots length between the control and treatments are identified as boron tolerant.

Redukcija rasta korena pšenice (Triticum aestivum L.) je jedna od posledica prisustva visokih koncentracija bora u zemljištu. Analizirana je varijabilnost genotipova pšenice u pogledu tolerancije korena na visoke koncentracije bora metodom naklijavanja semena na filter hartiji navlaženoj rastvorom borne kiseline koncentracija 0, 50, 100, 150 mg/l. Ispitivani genotipovi su ispoljili značajne razlike u dužini i broju korenčića na različitim tretmanima. Izdvojeni su genotipovi kod kojih je uočena vrlo mala razlika u dužini korenčića između kontrole i tretmana i koji se smatraju tolerantnim na visoke koncentracije bora.
