- 摘要:
- 以核桃楸砧木和普通核桃砧木为试材,研究了砧木对早实核桃‘绿岭’果实品质的影响。结果表明:核桃楸砧木与普通核桃砧木的‘绿岭’核桃果实纵径分别为3.914 cm与3.308 cm;横径分别为3.269 cm和4.039 cm;果形指数分别为1.199和0.819;青皮率分别为60.22%和52.87%;这4项均存在极显著差异。壳厚分别为0.102 cm和0.082 cm,差异显著。出仁率分别为59.28%和65.44%;脂肪含量分别为604 mg/g和642 mg/g;可溶性蛋白质含量分别为19 mg/g和11 mg/g,这3项均存在极显著差异。总蛋白质含量无明显变化。核桃楸砧木‘绿岭’果实中的亮氨酸、缬氨酸、异亮氨酸、苏氨酸、蛋氨酸等5种必需氨基酸和精氨酸、天冬氨酸、丙氨酸、脯氨酸等4种非必需氨基酸含量均极显著高于普通核桃砧木;钙、镁、锰含量均极显著高于普通核桃砧木,锌含量显著高于普通核桃砧木。
- 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.
