Penelitian tentang perkembangan bunga Pinanga coronata (BL. Ex Mart.)
Bl. yang bertujuan untuk mengetahui anatomi perkembangan
ginoesieum telah dilakukan. Pengamatan anatomi perkembangan
ginoesieum dilakukan dengan menggunakan metode paraffin. Bahan
disayat setebal 6–10 m dan diwarnai dengan Hemalum Mayer. Hasil
penelitian menunjukkan bahwa Bakal biji bertipe hemianatrop, bitegmik
dan krasinuselat. Megasporogenesis menghasilkan megaspora bentuk
linier dan megagametogenesis menghasilkan kantung embrio dengan
tipe Polygonium.

ABSTRACT
An investigation of the flower development of Pinanga coronata was
carried out to obtain information about anatomical development of
gynoecium. Anatomical observation were done by paraffin methods.
Serial section of then material were made at 6-10 m and stained with
Mayer’s Hemalum. The result showed that the ovule is hemianatropus,
bitegmic and crassinucellate. Megasporogenesis formatted a linier tetrad
of megaspores and megagametogenesis formed a Polygonum type
embryo sac.
