With complete abscission of all the leaves, the male cone cluster was up to 20 cm long, pendulous and spike-like forming a panicle. In early February, the male cones enlarged gradually and the microscopical protruded outside the scales. In mid-February, the male cones began to shed pollen.

Characteristics of male cone pinus

Explanation:

  • Male pine cones have littler structures than female cones and just live half a month. Dark colored, tube-like bunches on the parts of a pine, the cones contain scales, or microsporophylls, around a focal stem. Each scale holds a dust sack, or microsporangium, and every dust sack contains dust grains, each called a microgametophyte, or microspore.  
  • Through mitosis, microspores in the male microsporangium become male gametophytes, which are usually known as dust. The male gametophyte has two air bladders that will assist it with coasting reporting in real time when it is discharged by the male cone.
