杉木速生早期预测技术及生理生化基础的研究

Study on Forecast Technique of First Period of Quick Growing Chinese Fir and Its Physiological Biochemical Basis

1982年冬至1989年,我们开展了从种子阶段进行杉木速生早期预测技术及其生理生化基础的研究。在多年测试与种子活力有关的生理生化指标和大田多点试验,正反验证结果,表示种子活力的幼苗重量与高生长关系密切,与六年生以上杉木生长相关程度达80～90%以上。高活力家系与对照相比,其生长优势达到10%左右。表明以种子活力状况预测杉木速生与否是可能的,也是可靠的。

Study on forecast technique of first period of quick growing Chinese fir(Cunninghamia lanceolata) and its physiological biochemical basis were made from the winterof 1982 to 1989. Several years test on physiological biochemical index related with seed vigourseed and field trial showed that seedling's weight had close relationship with height growth,correlation degree reached 80～90% with over 6-year Chinese fir. Growth of high vigor familywas about 10% higher than the control. It showed that it was possible, even reliable toforecast growing Chinese fir according to seed situation.
