刺五加雌、雄花的花柱引导组织结构观察

利用光学显微镜、透射电子显微镜观察了刺五加(Eleutherococcus senticosus)雌、雄花的花柱及其引导组织的结构.结果表明:1.刺五加花柱处合生心皮内表面未完全融合,形成由中心向四周分支的裂缝；2.雌性花柱较雄性花柱,引导组织更为发达；3.发育过程中引导组织细胞内不断有储存为脂体的营养物质分解,并分泌...

Ultrastructure of stylar transmitting tissue in male and female flowers of Eleutherococcus senticosus

Structure of style and transmitting tissue was observed by optical and transmission electron microscope in male and female Eleutherococcus senticosus.The results showed that：（1） The inner morphological surface of the carpel didn＇t fused completely at style in Eleutherococcus senticosus,and gap can observed in cross-section of the style.（2） Transmitting tissue in female flower style is better development than in male flower style in all the developmental stage.（3） Lipid droplet in transmitting tissue cell seem to dissolved in the vacuole,and them diffuse and pass through the cell wall as intercellular substances.（4） After pollination the transmitting tissue cells deteriorated partly in female flower style,formed lysigenous intercellular space,in which pollen tube passed through.Lysigenous intercellular space and pollen tube were not observed in male flower style.
