  • Received Date: May 10, 2018
  • Revised Date: August 08, 2018
  • In October 2011, nuts of 9 individuals of 9-yearCaryaillinoensis‘Mahan’ were collected in Tonglu of Zhejiang province.Determinations were implemented on nut mass, length and width.Sowing and seedling cultivation was carried out in January 2012 in Hangzhou.Seedling height and ground diameter were measured in January 2015 and 2018.The result showed that it had great differences of fruit characters among different individuals (P<0.01).The greatest variation was the nut mass with mean coefficient of variance of 23.91%.There was extremely evident difference of height and ground diameter of 3-year seedlings among different individuals, while evident of height ground diameter ratio.The average seedling height of different progeny was 45.95-78.67cm, average ground diameter of 5.75-9.30mm and average height/ground diameter ratio of 6.95-8.88.Correlation analysis demonstrated that the growth of seedling height and ground diameter was significantly correlatedwith the mass of nut, with correlation coefficient of 0.63 and 0.71.There was no significant difference in height, ground diameter and height/ground diameter ratio of 6-year seedlings among different progeny.Comprehensive analysis indicatedthat ‘Mahan’hada large differentiationof fruit traits.The massof nuts was significantly correlatedwith the growth of 3-yearseedlings, but lower down of 6-year seedlings.
