Abstract

The giant corpse inflorescence (Amorphophallus titanum) is native to Indonesia. It is one of the flagships of The Center for Plant Conservation Bogor Botanic Gardens, Indonesian Institute of Sciences (LIPI) to raise public awareness for saving plants from extinction and caring the living environment. The blooming of the giant inflorescence attracts many visitors. Therefore, one of the research focuses of Amorphophallus titanum is how to predict the blooming-time in order to inform visitors earlier. The results of this study can be used as the basic information to predict the blooming of the inflorescences. Previous researchers had tried to predict the blooming based on firstly, the differential diagnostics of an inflorescence bud and leaf bud, and secondly, the growth pattern of the flowering bud from one individual sample only; whereas, our results suggested new findings. In this research, the prediction was examined from 2011-2012 on five individual samples planted in Bogor Botanic Gardens. We suggested that (1) the differential diagnostics of an inflorescence bud and leaf bud were not only based on the early bud shapes but also the growth rate, and (2) our results supported Lobin?s findings by providing a statistical formula for growth pattern of the flowering bud.

Abstract

Amorphophallus titanum is famous as the gigantic inflorescense and economically prospective due to its 20% glucomannan contents.Various cultivation techniques including germination have been conducted due to the delay in the seed germination of Amorphophallus titanum. Previous studies revealed that A. titanum seeds has not produced faster and better germination rate.Therefore this research was aimed to test the following hypotheses: (1) Fruit pericarp and the pericarp inhibited the germination,(2) testa/seed coat inhibited germination, (3) GA3hormone promoted the germination rate.The germination pattern was also monitored. The experiments consisted of:Experiment 1: sowing the fruit with the seeds inside and Experiment 2 with two treatments: testa peeling and GA3 hormone treatments. The results of Experiment 1 showed that the fruit pericarp and the pericarp inhibited the germination for 124 days. Experiment 2 resulted in: (1) the delay of the germination for 7-35 days caused by the testa/seed coat, (2) GA3 hormone promoted the germination rate 2.19 coefficient of germination rate; and higher GA3 (1000 ppm) may enhance the seedling growth (reached the highest 23.6 ± 1.3).We also recorded developmental stages from the seed germination, first-leaf emergence and tuber development in series of photographs overtime during the experimental period.
