【摘要】 在江西省余江县对引种自浙江省长乐林场的7个湿地松优良家系进行育苗试验,7个优良家系平均发芽率为76.23%,平均发芽势为62.65%,平均发芽时间为23.6 d,经9个月苗期观测,平均苗高27.63 cm,平均地径0.496cm,表现优于马尾松,平均地径甚至略高于赣州地区湿加松,初步表明,试验种源具有较好表现,在本区域具有良好适应性。此外,7个家系在发芽和生长表现上不完全一致,综合来看,4-12,4-19和Ⅲ-101三个家系表现较为突出,建议生产上优先考虑。更多还原

【Abstract】 The seedling cultivation of Pinus elliottii including 7 excellent families were introduced from Changle Forest Farm of Zhejiang Province, the seedling test was carried in Yujiang County of Jiangxi province. The results showed that the average germination percentage was 76.23%, the average germination energy was 62.65%, and the average germination time was 23.6days. After nine months observation in seedling stage, it was found that the average seedling height growth and average ground diameter growth was 27.63 cm and 0.496 cm, respectively, higher than P. massoniana, Some indicators are even higher than P. elliottii×P. caribaea in Ganzhou area. It means that the testing provenances have a good performance in this area and suitable for forestry production. In addition, the performance of germination and growth are not consistent in the 7families. Considering the height growth and ground diameter growth, the No. 4-12,No.4-19 and No. Ⅲ-101 families showed the best, which should be used a priority on the production.更多还原
