摘要: SUMMARY The culture of isotopically labelled plant material for subsequent experimental use is described. isotopes used were 65Zn in ryegrass chemical composition analysis related to animal nutrition, 22Na and 36C1 beetroot physiological ionic studies, 59Fe wheat grain human metabolic 45Ca germination the study calcium distribution seedling roots, 14C production humic substances. Consideration given various factors involved, such as methods incoporation label into plant, radiation damage, levels specific activity double labelling.
