摘要:

鹅掌楸属种间正、反交F1杂种及双亲的扫描电镜(SME)观察表明:马褂木和反交F1的下表皮细胞具明显乳突,北美鹅掌楸和正交F1则呈现平坦状;北美鹅掌楸和正交F1下表皮气孔密度显著高于马褂木与反交F1;杂种与双亲的下表皮蜡质纹饰和气孔器形态没有表现出明显差异;正、反交F1的气孔开口明显大于双亲。

Abstract:

The leaf abaxial epidermis micromorphologic characters of Liriodendron reciprocal cross hybrids and parents were observed under scanning electron microscope (SME).The results are as follows :Liriodendron chinense (Hemsl.) Sarg.and minus crossing F1 have obviously papillar cell in abaxial epidermis, that of L.tulipifera Linn.and plus crossing F1 is flat. Stomatal density of L.tulipifera Linn.and plus crossing F1 are much denser than that of L.chinense (Hemsl.) Sarg.and minus crossing F1.There are no significant differences in abaxial epidermal waxy ornamentation and stomatal apparatus form between hybrids and parents.Reciprocal cross hybrids have larger stomatal apparatus opening than parents′.
