Abstract
Seeds of folk varieties, Manno Kecil (Small Manno; MK) and both Manno Besar (Big Manno; MB) and MK were respectively collected in September 2005 (Exp. 1) in Yabaso village and in September 2006 (Exp. 2) in Yabaso and Kehiran villages, District of Sentani, Jayapura, Papua Province, Indonesia. The collected fruit weight of MK and MB ranged from 7.4 g to 44.6 g and 31.8 g to 46.2 g, with an average of 28.2 g and 37.6 g, respectively. The seed weight of MK and MB ranged from 5.8 g to 31.9 g and 21.7 g to 32.9 g, with an average of 20.4 g and 28.0 g, respectively. Fruit weight of both MK and MB was lower than that of the reported cultivated type of sago palms. The germination percentage of MK and MB was 70.1% and 77.3%, respectively, showing a slightly higher percentage in MB than in MK. These percentages were higher than those of the reported cultivated type of sago palms (40-60%). The seed germination of MK occurred from 6 to 69 days after sowing (DAS), showing a rapid increase (ca. 68%) from 20-34 DAS. These results suggested earlier and higher germination percentages during the rapid increase period of the wild-type Manno than in the cultivated type of sago palms. Further studies should be performed to clarify the effects of seed maturity and seed size or weight in Manno on the germination percentage and rate, using the collected fruits (seeds) from the plant.
