| Seedlings at the vegetative cotyledonary stage, about 7-10 days old, were transplanted into plastic pots containing the same medium. |
|
| Further development of cotyledonary embryo showing closed vascular system and characteristic cotyledonary notches. |
|
| In the first attempts to achieve embryo-to-plantlet conversion, 16-week-old cotyledonary stage embryos were selected for use as experimental material. |
|
| This explant consists of only cotyledonary ring along with intact cotyledons. |
|
| These species exhibit central implantation and have placentae of the diffuse and cotyledonary types. |
|
| QsHUB1 and QsHUB2 showed a transient increase expression from white callogenic structures and globular embryos to immature cotyledonary embryos. |
|
| On day 75 of pregnancy, placentomes from each ewe were fixed with Carnoy's solution by perfusion of the main vessel supplying the cotyledonary tissue. |
