The difference between male pine cones and female cones is in their size, shape, and color. Female pine cones are the characteristic woody, scaly ovoid cones that dangle visibly on pine trees. Male pine cones are the smallest types of pine cones.
The female cone (megastrobilus, seed cone, or ovulate cone) contains ovules which, when fertilized by pollen, become seeds. The female cone structure varies more markedly between the different conifer families, and is often crucial for the identification of many species of conifers.
The female cones of the Japanese White Pine are relatively small, measuring 6-8 cm (2.4-3.1 inches) and grow in clusters of up to 10 at the branch tips. In contrast, the male cones appear in larger clusters of about 30 higher up the branches.
Female pine cones from the ponderosa pine reach 4 inches when mature. They take two years to mature like the other pine cones. The tips of the pine cone’s petals have small, outcurved prickles. The pine cones are dark brown to orange-brown, depending on the tree’s age.
Male and Female Pine Cones. Interestingly, pine trees produce male and female cones, each playing a distinct role in the reproductive cycle. Male cones, often smaller and more inconspicuous, produce pollen, the fine powder that carries the tree’s genetic material.
Pine cones are the reproductive parts of a pine tree. Some cones are male and release pollen to fertilize female cones. The female cones then produce seeds. Pine trees have cones to protect their seeds until they are mature. As Gymnosperm trees, their name means ‘naked seeds’ in Greek.
Female pine cones contain a single winged sand pine seed with a tear-shaped seed at the base. An inedible hard shell surrounds pine seeds. As the pine scales or plates open, the papery wing of the pine cone seed releases them in the wind.
Seed bearing cones are female, while pollen filled cones are male. Both sexes of cones grow on the same tree, but male cones grow on lower branches so that the wind can blow pollen up to the female cones.
Let’s start with female pine cone formation. In the months of spring, mostly in the uppermost branches of the pine tree branches, small, green female pine cones begin to form. They come out of those branches that instead of adapting leaves, have formed scale-like structures.
Female pine cones can be identified by their characteristic scaly, woody exterior, and ovoid shape. They hang down from the branches of pine trees. To put it another way, male conifers are smaller than female conifers.
