Maybe the white starchy substance can be used, but it hardly seems like good plant material compared to other embryos that are in the plant world.
Banana embryos are actually quite easy to find and easily removable, and the practice of germinating them in vitro is very routine in breeding. It looks like a little yellowish-offwhite mushroom sitting right below the "hole" in the seed.





This picture is kind of poor, but it is 2 Ensete glaucum embryos germination on my windowsill, the smallest one is the 3rd one which did not germinate (appearently due to mild contamination perhaps). This was just for fun, its using normal micropropagation subculture medium instead of something that would better develop a seedling, but it seems to have gotten them to start growing at least, they began to develop about 4 days after initiation and over 3 years after purchase. In this photo they are about 15 days old and each is forming shoots (one has split into 2 shoots actually and is the first to start growing some roots as well).
