Morphological Characteristics Analysis of Three Introduced Seed Types of Quercus L
Objective] Morphological characteristics of three introduced seed types of Quercus L.were analyzed to enrich the resources of Quercus L.in China, and to breed the high-quality variety.[ Method] With Quercus coccinea Muench, Quercus palustris Muench, Quercus rubra L.and Quercus wutaishansea Mary as the research objects, we analyzed the morphological characteristics of seeds.[ Result] Grain weight had significant differences in different seed types.The minimum grain weight was Quercus palustris Muench (1.69 g on average); the maximum grain weight was Quercus rubra L.(5.91 g on average).The difference of the two was 4.22 g.Quercus rubra L.had the maximum grain length (2.25 cm on average).Quercus palustris Muench had the minimum grain length (1.33 cm on average).The difference of the two was 0.92 cm.Quercus rubra L.had the longest diameter (2.07 cm on average); and Quercus wutaishansea Mary had the shortest diameter (1.29 cm on average); the difference of the two was 0.78 cm.[Conclusion] Morphological characteristic index is an important basis for the classification of Quercus L..
