n.
The diploid spore-producing phase in the life cycle of a plant that exhibits alternation of generations. It is the dominant stage in vascular plants.

sporophyte

(ˈspɔːrəʊˌfaɪt; ˈspɒ-)
n
(Botany) the diploid form of plants that have alternation of generations. It develops from a zygote and produces asexual spores. Compare gametophyte

the form of a plant in the alternation of generations that produces asexual spores. Compare gametophyte.

spo·ro·phyte

(spôr′ə-fīt′)
In plants, fungi, and certain algae, the individual organism or generation of organisms that produces spores. A sporophyte is formed from the union of the nuclei of male and female reproductive cells, and each of its cells has two sets of chromosomes. In nonvascular plants, such as the mosses and liverworts, the sporophyte is a small plant or a part that grows on top of the gametophyte. In vascular plants, such as the ferns, grasses, conifers, and flowering plants, the sporophyte is the main form of the plant. Compare gametophyte.

Small populations with sporophytic incompatibility systems can be expected to experience a reduction in seed production caused not by low or infrequent pollinator visitation depositing few pollen grains but rather by a limited number of compatible mating types within the small population (quality or mate limitation; Aizen and Harder, 2007; Campbell and Husband, 2007) as S allele diversity declines (Les et al.

In other species, the sporophytic cycle is seasonal although the gametangial cycle is not, e.
In this project, we will focus on the sporophytic self-incompatibility system in outcrossing Arabidopsis species, a model biological system in which two distinct co-evolutionary processes are becoming well-understood: 1) between the male and female reproductive proteins allowing self-pollen recognition and rejection and 2) between small non-coding RNAs and their target sites that jointly control the dominance/recessivity interactions between self-incompatibility alleles.
Staminate plants, with male flowers only, are routinely called males, and pistillate (carpellate) plants, with female flowers only, are called females, and this standard terminology (albeit technically incorrect, since the sporophytic phase of plants is asexual) is followed here.
The primary leaf enters into a natural stage of senescence after the first weeks of the sporophytic phase, and is replaced by secondary bilobed leaves, characteristic of the adult plant.
According to Maheshwari (1950), supernumerary embryos of sporophytic nature can originate from nucellus or integuments cells, by zygote or pro-embryo cleavage and differentiation of suspensor cells.
The life cycle of land plants alternates between a diploid sporophytic generation and a haploid gametophytic generation.
