| These nutrients enter the seed through a single vascular bundle in the funiculus that extends into the seed coat as the chalazal vein and its two lateral branches. |
| 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. |
| No changes in the staining of chalazal cell walls were detected at the end of grain filling. |
| In addition, a strong staining was observed in maternal chalazal tissue shortly after fertilization, and persisted throughout seed development. |
