| Abstract |
The sensitivity to atrazine was observed in 24 wheat varieties lines with the concentration of 3000 mL/ ha 40 % atrazine solution. The varieties showed different responses to the application of atrazine. Some of them were of tolerance with most plant s growing normally and/ or slightly injured. Others were susceptible to atrazine, most of the plants were severely injured and even died. The remaining varieties were classified to medium susceptible or medium tolerant. Investigation indicated that the root s of wheat were more severely damaged than the top part s. Response to atrazine, which had not relation with cytoplasm, was cont rolled by a single nuclear gene, as revealed by segregation ratios of the susceptible plant s to the tolerant ones in F1, F2 and BC1 hybrids between different response varieties. The sensitivity was recessive, whereas the tolerance, dominant. The effect s of atrazine on immature embryo culture were also noticed. High concent ration (100 mg/ L) of atrazine that added to the media reduced the callus induction, yet low concentration (25 mg/ L) did not substantially influence the callus induction in the present study. At razine had some effect s on callus developing state during subculture regardless its concentrations in media. |
