Lemma

dioecious

Etichetta di dominio

EN

Etichetta grammaticale

Adj.

Definizione

Of or relating to organisms, especially plants, having the male and female reproductive organs borne on separate individuals of the same species; sexually distinct. 1

Nota

A plant species is said to be dioecious when its male and female reproductive organs are carried on separate individual plants of the same species. When a plant species is dioecious, at least one male plant must be present in a group for the fruit-bearing female plants to be pollinated. 2

Contesto

Consider the unusual-looking actinidia, especially the species Actinidia kolomikta. This spectacular vine, which is native to Asia, is a vigorous grower. It usually evokes some sort of comment, for it has variegated foliage: green, pink and white on the same leaf. The male form of this dioecious vine has the white or pink-tip leaves. 3
