Abstract

Corpse flower (Amorphophallus sp.) is a type of flora endemic to Indonesia which belongs to the Araceae family. Corpse flowers are compound flowers that have flower stalks and single flowers. This research aims to determine phenology, germination percentage and the effect of planting media on Amorphophallus gigas seedlings. This research was carried out in September-December 2023. Observations of flower phenology included flower development, budding period, blooming period, and when the flowers began to wilt. The source of the seeds comes from Luat Lombang village, and the source of tuber seeds comes from the villages of Aek Nabara, Sipenggeng, Luat Lombang and Pancur Napitu. Based on observations of the phenology of corpse flowers, planting of Amorphophallus gigas (Aek Nabara) was carried out on October 9 2023, shoots appeared on November 12, flower peak blooming was on December 8, withering phase was on December 10. The corpse flower Amorphophallus gigas (Sipenggeng), buds appeared on 2 Dec, peak blooming on 24 Dec, flowers withered on 28 Dec. Phenology Results of Amorphophallus gigas (Sipenggeng) leaves planted on 09 Oct 2023 weighing 6.8 kg, vegetative shoots appeared in the 8th week, leaves appeared in the 12th week, and began the dormant period in the 24th week. Growth of Amorphophallus gigas tubers (Luat Lombang) planted on 09 October with a weight of 800 g, vegetative shoots appeared in the 15th week, leaves appeared in the 20th week, starting the dormant period in the 36th week and the growth of Amorphophallus gigas (Pancur Napitu) was planted on 09 October with a weight of 50 g , vegetative shoots appear in the 1st week, leaves appear in the 8th week, starting the dormant period in the 27th week. From the observation results it can be seen that the greatest growth in height is the Sipenggeng tube, carcasses are sand media. Sand media has a germination percentage of 97.5%.
