In addition, a strong staining was observed in maternal chalazal tissue shortly after fertilization, and persisted throughout seed development. |
The stalk is usually longer, the chalazal scar larger and often oval in outline, and the grooves on the back of the pip parallel to each other. |
Currently an autapomorphy for Cyanastrum, although may be homologous with chalazal elaiosomes or pachychalaza in other taxa. |
Nevertheless there are curious points to be investigated in the earlier stages of development, such as the vascular supply and the chalazal lobings. |
Moreover, within an embryo sac, endosperm nuclei were always of the same size, with no typical chalazal cyst formed in endosperms with three or more syncytial mitoses. |
Note the chalazal vascular bundle that encircles about three-quarters of the seed and the two short side branches that contain phloem only. |
