摘要
厚朴不同种源树叶形状从先端急关到裂成2钝圆裂片，存在渐变过程，又有遗传稳定性，大体上可以分为3个类型。不同种源厚朴苗木和幼林高生长、物候期、生长节律都存在明显的差异，差异的变异与树叶形状类型存在显著的相关。幼林高生长估算遗传力达到0．52～0．69，具有中等以上的遗传力。
The blade profiles of Magnolia officinalis from the different provenances had anamorphism and genetic stability. They were classified into 3 types. Among the provenances, high growth of sprout, phenological phase and growth rhythum had sigmifical differences. The variances of differences significally related to the blade profiles. The heritability estimated by high growth of sprout, reached 0. 52～0. 6g. which was above average.
