孢子果

一些水生蕨类的孢子囊群，由特化的羽片或囊群盖包被所形成的一种卵形、肾形或球形体，如苹属的孢子果的壁为羽片特化而成，内含多个孢子囊群，每个孢子囊群中杂生有大、小孢子囊；再如槐叶苹的孢子果球形，孢子果的壁由囊群盖特化而成，而且有大小孢子果之分，大孢子果的体积稍小，内含少数大孢子囊，小孢子果稍大，内含多个小孢子囊；满江红的孢子果的壁也是由囊群盖特化而成，也有大、小孢子果之分，大孢子果较小，内含１个大孢子囊，每个大孢子囊中仅产１个大孢子，小孢子果较大，内有多个小孢子囊，每个小孢子囊中产生６４个小孢子.Some aquatic fern sori from the specialization of the pinna, or cover-coated capsules group formed a kind of oval, kidney-shaped or spherical bodies, such as the ping is a fruit of the spore wall made for the pinna specialization containing multiple sori, sori in each mixed together large and small sporangium; another example, the spores of Salvinia ping fruit spherical, spore wall of fruit-based gate formed by the capsule group, but also the size of spore fruit of the points, large spore size of fruit is smaller sporangia containing a few large and small spores slightly larger fruit, containing several small sporangium; Azolla spore wall is also the fruit group from the gate of the cystic Cheng, there are large and small spores divided fruit, large fruit spores smaller, containing a large sporangium, each large sporangia produced only one large spore, Microspore fruit large, there are several small spores capsule, each small sporangia produced 64 small spores.
