from Wikipedia, the free encyclopedia

A perisperm is a nutrient tissue in plant seeds that emerges from the nucellus . In water lily plants , pepper plants and ginger plants , it exists alongside the endosperm . In contrast, it serves as the sole nutrient tissue for many carnation species . In contrast to the mostly triploid endosperm , the perisperm is diploid and it consists mainly of starch .

Similar is the rare Chalazosperm , which is also diploid and emerges from the Chalaza adjacent to the Nucellus. This can occur alone or together with the perisperm if there is no endosperm.
