Abstract:
Growth and fruit characters of 4a Schima superba clonal seed orchard in Xipi Stateowned Forest Farm, Hua′an County, Fujian Province were investigated. The results showed that ground diameter change range was 783-1380cm. The diameter change range was 468-938cm. The bifurcation number change range was 10-25. The clear bole height change range was 333-2990cm. The tree height change range was 330-488m. The crown width change range was 233-380m. The seed setting rate in 2014 and fruit setting rate in 2015 of A4 were the highest, up to 75%, they were 282 times and 421 times of the average, respectively. The seed setting rate was 2727% in 2014, fruit setting rate was 2091% in 2015. In 33 clones, 8182% of the clones had seed in 2014, 6061% had fruit in 2015, 1818% without fruiting in two years. The correlation between 2014 seed setting rate and 2015 fruit setting rate was extremely significant, whose correlation coefficient was 083. The seed setting rate and fruit setting rate were positively correlated with diameter, reached a significant level. The comprehensive score of A4 was the highest, up to 33442.
