Water and Nutrient Use Efficiency in Diploid, Tetraploid and Hexaploid Wheats

Abstract: Three diploid (Triticum boeoticum, AA; Aegilops speltoides, BB and Ae. tauschii, DD), two tetraploid (T. dicoccoides, AABB and T. dicoccon, AABB) and one hexaploid (T. vulgare, AABBDD) varieties of wheat, which are very important in the evolution of wheat were chosen in this study. A pot experiment was carried out on the wheat under different water and nutrient conditions (i) to understand the differences in biomass, yield, water use efficiency (WUE), and nutrient (N, P and K) use efficiency (uptake and utiliz… Show more

“…In the second year, the amount of nitrogen taken up by Tir and C-1252 varieties decreased depending on decreasing grain yield. It was stated that plant nutrient increased depending on increasing number of genomes and nutrient uptake efficiency increased depending on fertilization (Huang et al, 2007). In the second year, there was a decrease in the annual average of grain yield but an increase in biological yield values, resulting in a difference between years in terms of N uptake.…”

“…Stomatal conductance and D consequently appear to be negatively associated to stomatal frequency and positively to stomatal size. In the genus Triticum, water use efficiency (WUE) was found by Huang et al (2007) and Zhang et al (2007) to be highly dependent on ploidy level, with the higher WUE being found in hexaploid wheat and the lower in diploid wheat. Variation in water use efficiency among species appears to relate more to variation in harvest index or water extraction than to differences in transpiration efficiency (Khazaei et al 2008(Khazaei et al , 2009Shao et al 2008aShao et al , b, 2009).…”

“…The results might be due to high water‐induced nutrient loss in soil and nutrient uptake by plants at high water supply. The changes in soil nutrient status might have influenced leaf‐traits related to nutrient conservation, including green‐leaf N and P concentrations (Guo et al 2007; Huang et al 2007; Zhang et al 2007) and N‐ and P‐ resorption traits.…”
