摘要
本文研究了油松、侧柏、落叶松种子9个种批的生活力与其室内发芽和田间播种各项指标的相互关系,结果表明针叶树种子生活力与上迷各项指标间存在着显著和极显著的相关关系。根据生活力测定结果可以推算出室内发芽和田间播种各指标的理论值,这对于快速确定种子的种用价值具有重要现实意义。
The intenelationships among viability, indices of indoor germination and field sowing tests in 9 seed lots of Pinus tabulae formis Carr., Platycladus orientalis (L.) Franco and Larir principis—rupprechlii Mayr. were studied. The results showed that the significant and highly significant correlations were present between the viability and each of other two indices in coniferous seeds. The theoretical value of the indices could be calculated according to results of viability dertermination. It was practical and significance in rapid defining seeding value of seeds.
