Abstract:
With Juglans mandshurica Maxim.and Juglans regia L.as test materials，the effect of rootstocks on the quality of which was a kind of precocious walnut was researched in this paper.The results showed that the vertical diameter of nut with J.mandshurica and J.regia rootstock were 3.914 cm and 3.308 cm，and the transverse diameter were 3.269 cm and 4.039 cm，respectively.The index of shape were 1.199 and 0.819，and the content of walnut green husk were 60.22% and 52.87%.There were very significant difference with the 4 index above.The shell thickness of nut with J.mandshurica and J.regia rootstock were 0.102 cm and 0.082 cm，and there was significant difference between them.The kernel percent of nuts with J.mandshurica and J.regia rootstocks were 59.28% and 65.44%.The content of fat were 604 mg/g and 642 mg/g，and content of soluble protein were 19 mg/g and 11 mg/g.There were very significant difference about the three index above，also.However，there was no difference about the content of total protein between the two kind of nuts.Compare to nut with J.regia rootstock，the contents of leucine，valine，isoleucine，threconine，methionine which were classified as essential amino and arginine，aspartic acid，alanine，proline which were classified as nonessential amino in nut with J.mandshurica rootstock were more，and very significantly.Contents of Ca，Mg and Mn were very significantly more，and Zn was significantly more in nut with J.mandshurica rootstock.
