Tessie C. Nuñez ABSTRACT A simple means of deriving two seedling from a hybrid macapuno embryo was developed. Macapuno embryos were allowed to grow in vitro for 1 to 1.5 months or until the shoots and roots emerged. Germinating embryos were cut longitudinally, equally dividing the shoots and roots. Split embryos were then subcultured in …
