| Abstract: | Based on the determination of the growth characters and timber basic density of open-pollinated progenies in 11-year-old Pinus massoninana clone seed orchard,the results indicated that there were significant difference between families in tree height,DBH,individual volume increment and basic density,respectively.The 10 selected clones with fast growth and high quality had individual volume 0.1568 m3 and basic timber density 0.3507 g/cm3 of its progenies.Compared with the population average value,their gains... |
