Influence of Genetic Variability on Zinc Response in Wheat
1974
Shukla, U. C. | Raj, Hans
Influence of genetic variability on Zn response in wheat (Triticum sp.) was evaluated in the greenhouse. There was considerable difference among 21 varieties in the time of appearance and intensity of deficiency symptoms, yield depression, and Zn concentration under Zn stress conditions. Without supplemental Zn, dry matter yields of shoot and roots were 8.6 to 33.5% and 9.4 to 36.8% lower, respectively, than at 5 ppm Zn level. Zinc concentration of varieties ranged from 4.2 to 28.3 ppm under zinc deficiency conditions. The differential response among the varieties was found closely linked to their efficiency in Zn utilization from the soil.
