Growth Characteristics and Starch Productivity of Folk Varieties of Sago Palm around Lake Sentani near Jayapura, Papua State, Indonesia

説明

<p>The names of 21 folk varieties of sago palm (hereafter varieties) were mentioned by the sago palm growers around Lake Sentani near Jayapura, Papua State, Indonesia, which is included in the sago palm’s area of origin, based on the earliness of flowering, morphological differences, starch yield and quality, ecological characteristics, etc. Among these varieties, 8 major varieties focusing on starch productivity were selected, and 5 to 7 palms of each variety were sampled at the optimum harvest stage (flower bud formation to fruit-setting stage) to obtain and compare their growth characteristics and starch productivity. The early-flowering variety (one variety) had a short growth period of about 13 years, but both the trunk length and diameter were inferior to those of the late-flowering varieties (years to harvest: 19 to 21 years), and the starch productivity was also lower. In late-flowering varieties (7 varieties), differences in the trunk weight and volume were found due to differences in the trunk length and diameter. The varietal difference in starch percentage in the pith was small, so the starch content (yield) was determined by the pith dry weight, closely related to trunk weight and volume. The starch content was highest for the variety Para, which showed an average content of 674 kg, with a maximum content of 975 kg. The content of macronutrients in the pith tended to be higher in the order of K> N> Ca> Mg> P, and the content per plant was mainly determined by the pith dry weight.</p>
