carpogonium การใช้

• Upon their collision, the walls of the spermatium and carpogonium dissolve.
• The initiation of Gonimoblast filament starts from the ventral side of Carpogonium.
• They can also reproduce via spermatia, produced internally, which are released to meet a prospective carpogonium in its conceptacle.
• The male nucleus divides and moves into the carpogonium; one half of the nucleus merges with the carpogonium's nucleus.
• The male nucleus divides and moves into the carpogonium; one half of the nucleus merges with the carpogonium's nucleus.
• Carpogonium slightly protruded or broader on ventral side and 7.50 to 12.85 祄 in diameter, trichogyne cylindrical elongated with wavy margin.
• The genus Sirodotia has been recognized by the two important reproductive characters such as asymmetrical carpogonium in the gametophyte and indeterminate / indistinct gonimoblast filament in the carposporophyte.
• The trichogyne will continue to grow until it encounters a spermatium; once it has been fertilized, the cell wall at its base progressively thickens, separating it from the rest of the carpogonium at its base.
• Further recognition of species inside the genus is done by various distinct characters like morphology of the gametophyte, position of spermatangia, position of the carpogonial branch, gonimoblast filament arising from the side of from carpogonium, and the size of the carpogonium.

• Spermatangia are produced in separate male plants on both primary and secondary laterals, apical or sub apical in position which are either single or in clusters, pairs are also common . First carpogonial branch arises at 15 30th axial cells, 1 2 per basal cell, 3 5 cell long, slightly curved with distinctly stalked cylindrical trichogyne on the dorsal side of asymmetrical carpogonium.
