摘要
马尾松( Pinus massoniana)是我国南方重要的工业用材及采脂树种,在我国林浆纸(板)一体化和松脂产业中发挥着重要作用。国家"六五"至"十五"期间以生长和材性为选择指标进行了地理种源/家系/无性系选择和改良,其间,"八五"国家科技攻关项目"马尾松产脂类型研究"曾经在南方六省(粤、桂、闽、赣、皖和浙)开展了产脂性状的改良,进行了高产脂优树选择、基因库营建、第一代种子园建立、优树自由授粉子代林营建等研究工作,取得了一定的成果(广东省高脂松研究协作组,1988;郑元英,1988;章洪明等,1988;颜聪炎,1991;曾令海等,1998;连辉明等,2002)。
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.
