|
| For the oak tree, these constraints are a tangible hindrance to its improvement, but they could be overcome through the use of somatic embryogenesis. |
|
| A long-term developmental trend begins after the definition of the growing point in early embryogenesis and continues thereafter through juvenility and the period of vegetative growth into the reproductive phase. |
|
| It is an extension of previous research in the embryogenesis of Japanese quails in weightlessness, which was carried out on board the Mir space station. |
|
| The objectives of this study are to document the key anatomical events in the embryogenesis of two Gastrodia species during the courses of megasporogenesis, megagametogenesis, fertilization and seed maturity. |
|
| During ovarial develop-ment, lipids synthesized in the fat body are transported to the developing ovary, and stored for use in embryogenesis. |

|
| The details of early embryogenesis in gymnosperms vary considerably. |
|
| In vascular plants embryo formation, or embryogenesis, usually occurs within a few hours after fertilization, with the first cell division that cleaves the zygote, or fertilized egg, into two daughter cells. |
