provenances of different Castanopsis hystrix elite trees

The growth traits of progeny seedlings of 13 Castanopsis hystrixr elite trees，from three differentprovenances were compared. The results showed that Guangxi provenance had the largest thousand-grain weightwith 968.64 g， and followed by Guangdong and Fujian provenances. The seed length and seed width of the threeprovenances showed the same rule as thousand-grain weight. The differences in thousand-grain weight，ground diameterand seedling height of different provenances were significant. It took 25-34 d from sowing to germination，and thecumulative days of budding were 62-76 d. The earliest time of budding was Guangxi provenance，and the fastest growthof progeny seedlings was also appeared in Guangxi provenance，the ground diameter and seedling height were 0.35 cm，24.04 cm，respectively. The ground diameter and seedling height of the best provenance were 1.12 times and 1.17 timesof those of the worst provenance. The correlation analysis results showed that the thousand-grain weight had significantpositive correlation with ground diameter and seedling height.
