The new variety had oval nut, circled base of fruit and lightly sharp top fruits with the average single fruit weight of 14.44 g, and the shell engraved a large shallow with wrinkle surface. The suture line was protuberant and tight, and the shell thickness was 0.89 mm. The inner fold wall had paper quality, and diaphragm was well-developed. The kernel rate was 51.2% with rough fat content of 74.67%, protein content of 18.5%. And it was easy to peel off the kernel, which was large and full with delicate taste. ＂Ludian-dama No.1＂ passed the examination and approval of the Forest Variety Approval Committee of Yunnan Province in December, 2014.展开更多

Comparison shows that Qingxiang has strong tree vigor, making it suitable for loose planting, needs pollination tree, bears food late and shows very stable yield performance, while Liaohe 1 has medium tree vigor, bears food early and shows stable yield performance. Based on years of regional planting tests, suggestions were proposed to the high yield cultivation techniques of walnut.展开更多

Studies have reported that mortality from Coronary Heart Disease (CHD) in diabetic patients is 2 - 4 times higher than nondiabetics. In this respect, walnut is a treatment which has beneficial effects on CHD risk factors. PPARα and SREBP-1c play an important role in the regulation of lipid metabolism. This study was aimed to evaluate the effects of walnut on lipid profile as well as SREBP-1c and PPARα protein levels in rats. Animals were randomly divided into 3 groups (n = 6);Group 1: Received chow only (control), Group 2: Diabetic rats + chow, Group 3: Diabetic rats + chow supplemented with 4% of whole walnuts. After four weeks rats were sacrificed, blood was collected;lipid profiles as well as SREBP-1c and PPARα protein levels were determined. Compared with diabetic rats walnut significantly decreased serum cholesterol (P < 0.01), LDL-c (P < 0.01), triglyceride (P < 0.001) and VLDL-c (P < 0.001) and also increased HDL-c (P < 0.05) compared with diabetic. Moreover, SREBP-1c protein level significantly decreased (P < 0.05) and PPARα significantly increased in walnut group compared with diabetic group (P < 0.05). The findings showed that walnut administration in diet clinically decreases atherosclerosis risk factors. Lipid profile reduction might be due to the rise of PPARα and the reduction of SREBP-1c by this medical treatment in liver.展开更多
