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。
In this paper, the relationship between the viability of nine species of Pinus tabulaeformis, Platycladus orientalis and Larix gmelinii and their indoor germination and field sowing indices was studied. The results showed that there was a significant positive correlation between the vigor of coniferous trees and the above indexes Significant correlations. According to the results of the determination of viability, the theoretical values of indoor germination and field sowing indexes can be calculated, which has important practical significance for quickly determining the seed value.
