应用实体解剖镜对兴安落叶松、长白落叶松、华北落叶松３种１９个种源种子的９项２１个指标进行了比较形态研究，通过对各形态指标的观察比较与统计分析，确定了鉴别３种落叶松种子的主特征和辅助特征；绘制了１９个种源种子的聚类谱系图；提供了应用解多元一次方程组确定混杂种子中３种落叶松所占比例的方法，拍摄了形态特征照片。
The morphological characteristics of nineteen 21 species of three provenances of Larix gmelinii, Larix olgensis and Larix principis-rupprechtii were studied by using physical dissecting microscope. Through the comparison and statistical analysis of morphological indexes, The main characteristics and auxiliary characteristics of three kinds of larch seeds were obtained. The clustering phylogeography of 19 provenances was drawn. The method for solving the proportion of three kinds of larch in mixed seeds by using the solution of multiple linear equations was provided. Feature photo.
