Abstract
STIMULATORS of plant cell division have been demonstrated in several types of fruits1–3 and seeds4,5. Stimulators of cell division have been reported in the fruitlets of apple, plum, peach, pear, quince and pumpkin1. Explants from the secondary phloem of carrot roots were used for bioassay. A highly active kinetin-like preparation has been isolated from peas and has been described as containing at least one active purine derivative which is different from kinetin5. Cell division factors from apple fruitlets and coconut milk have also been reported3.
