Abstract

Agathis labillardieri fruits can be distinguished according to their colours into three different colours i.e. light green and green. This study examined variation of dimension and moisture content of Agathis labillardieri based on those colours. The fruitys are measured their avarege fruits diameter, fruits length, fruit weight, moisture content and and germination percentage. The expweriment were laid out as a Completely Randomized Design. The result indicated that mature fruits have dark green colour. The charateristics of these green fruits are germination percentage 91 %, moisture content 31.2 %, fruit diameter 8.6 cm, length 8.7 cm and fruit weight 526.97 gr.

Abstract

Research on tisuk (Hibiscus macrophyllus) wildlings was conducted in the private forest area in Pasirbatang Village, Manonjaya Sub-District, Tasikmalaya District. The material of tisuk wildings was grown in nursery area of Ciamis Forestry Research Institute. The research was conducted on September 2007, starting with the private forest observation, which covers the potency of natural seedling spreading and the measurement of 2 years old-tisuk wildling, which came from natural seedling. The diameter growth of 2 years old-tisuk natural seedling that belong to the private forest farmer are 5.6 cm, 4.9 cm and 7.1 cm, while its height are 6.0 cm, 6.3 cm and 7.1 cm. The huge number of tisuk wildling availability under the tisuk stand has high potency to be the material for forest regeneration. Some of its techniques are covering the big tree selection, tisuk natural seedling selection, taking off, packaging, tisuk natural leaf cutting, replacement and seedling maintaining.
