5个薄壳山核桃品种果实性状综合评价OA

To explore the growth and development patterns as well as economic characteristics of the fruits of the Carya illinoinensis,this paper used 5 varieties of Carya illinoinensis,namely Jinhua(JH),Mahan(MH),Stuart(ST),Pawnee(BN),and Yalin 21(YL21),as the research materials.Changes in fruit length and width were analyzed,and indicators such as fresh fruit weight,dry fruit weight,and kernel weight for different varieties were measured.The results showed that the fruit length and width of the 5 types of Carya illinoinensis reached their maximum in September.The fruit lengths were 42.2,72.4,42.4,59.9 and 54.9 mm respectively,and the fruit widths were 29.1,35.1,30.9,37.7 and 31.1 mm respectively.The fruits rapidly expanded in late June and early August,and then basically stopped growing after mid-September.The kernel weight of BN was the largest,at 6.95 g,and the kernel extraction rate was good with a low shrunken rate.Overall,the single fruit weight of BN is excellent,with a high kernel yield and a low rate of empty or shriveled fruits.It is an ideal choice for orchard cultivation.
