Abstract: Studies were carried out onmineral elements in Torreya grandis 'Merrillii' seeds and their forest soils . The results are the following .(1)In the soils , total nitrogen , total phosphorus and hydrolytic nitrogen are rich , while available potassium insufficient .Ferrum , boron , manganese are rich and coefficients of variation are small. Cadmium and hydragyrum are undetectable , coefficients of variation of arsenic , chromium , cuprum are big while those of zinc and plumbum small , and in some soil samples , the contents of arsenic , chromium, cuprum and plumbum exceed the standard .(2)In the seeds , nitrogen , phosphorus , potassium, calcium and magnesium are abundant and their coefficients of variation are under 16 %.Manganese , cuprum and zinc are plentiful , and the coefficients of variation are small , while those of ferrum and boron are between 147.69 % and 112.99 %, respectively .Among the heavy metals , cuprum , zinc and hydragerum contents are under the safe line , and plumbum and chromium are undetectable .Only arsenic content excesses the standard in some samples .(3)Of most mineral element contents , there are no correlations between the soils and the seeds , except those of calcium and ferrum and nitrogen .[ Ch , 8 tab .19 ref .]
