Comparative Study on the Resin Yield and Rosin Components of Pinus massoniana Superior Provenances among Different Ages
摘要
Abstract
The resin yield and rosin components of Tongmian and Gupeng provenances of Pinus massoniana were compared respectively in the 6-,8-,10-,12-,15-and 20-year-old stands. The results showed that the resin yield of Tongmian was lower than Gupeng at the all ages,however the mature time of resin yield was about 4 years earlier than Gupeng’s. The contents of resin acids,abietic resin acids,Hawasong type resin acids,dehydroabietic acid and the resin acid oxide were used as comprehensive evaluation index,by which the rosin quality of Tongmian provenance was higher than Gupeng’s. The rosin quality of Tongmian and Gupeng reached to the highest when the trees were 10-year-old and 20-year-old,respectively. Based on the results,the Tongmian would be suitable to a short rotation used for resin production or timber and resin production stands. Resin tapping can be started at the 7 th to the 10 th year and felling can be conducted at the 17th year. However,the Gupeng would be suitable to a long rotation. The tapping time is better to start during 11-to 15-year-old and the final felling can be conducted at 26 years old.关键词
