Pakistan Journal of Biological Sciences1028-88801812-5735Asian Network for Scientific Information10.3923/pjbs.2000.883.884M.Yaseen, HussainT. 5200035Response of genotypes was measured in terms of shoot (SDM) and root (RDM) dry matter weights, root-shoot ratio and relative SDM, P concentration. Relative reduction in SDM ranged from none to 54 percent. Genotypes with none or little influence of P deficiency stress on SDM were Kohinoor-83, Pb.85, Parvaz-94 and 4770. Highly P responsive genotypes includes Faisalabad-83, Chakwal-86, Pasban-90, 4072, 4943, 5039, 6529-11 and 6544-6. Differences in SDM exhibited the presence of genetic variation among wheat genotypes under P-deficient conditions. There was 29 percent increase in SDM with increase in P supply. Phosphorus supply levels significantly affect the root dry matter. High RDM at rock-P level indicated adoptation to the P stress. This was also clear from high root-shoot ratio at this P level. Genotypes with high root-shoot ratio showed better adoptation to low P conditions. Except Pak.81 and Parvaz-94 all the other wheat genotypes had greater ratio at rock-P than at adequate P level.]]>Burauel, P., J. Wieneke and F.
