Introduction Evaluation of Nine Carya illinoinensis Varieties in Hechi of Guangxi
摘要
Abstract
In order to select excellent varieties of Carya illinoinensis which are suitable for popularization in Hechi of Guangxi,taking nine 7-year-old C.illinoinensis varieties which were introduced and planted in Dashantang forest farm in Hechi as materials,indexes including nut yield,nut phenotypic traits and nutritional components of kernel were determined.Taking ten indexes,principal component analysis was used for compre-hensive evaluation of nine varieties.Results showed that coefficient of variation of nut yield of single plant was the largest(82.30% ).Nut yields of single plants of nine varieties ranged from 0.08 to 2.03 kg,which was the highest in'Pawnee'.Nut rate of single plant of'YLC13'was the highest(44.90% ).Nut weight of'San Saba Im-proved'was the largest(8.20 g).Kernel weight of'YLC13'was the largest(4.47 g).Kernel rate of'Pawnee'was the highest(58.54% ).Fat contents in kernels of nine varieties ranged from 422.62 to 742.31 mg/g.In fatty ac-ids,oleic acid contents were the highest in nine varieties,accounting for 64.92%-74.54% of fatty acid contents.Contents of fat and oleic acid in kernel of'Mohawk'were the highest.Total sugar content in kernel of'MS1'was the highest(88.51 mg/g).Protein content in kernel of'Mahan'was the highest(118.64 mg/g).Tannin content in kernel of'Pawnee'was the lowest(2.80 mg/g).Principal component analysis on ten indexes of different varieties showed that'Mohawk''Pawnee'and'YLC13'had higher comprehensive scores,which could be popularized in Hechi of Guangxi.关键词
