Abstract

Timoho (Kleinhovia hospita L) is a rare plant that has high economic and cultural value for the Javanese people, especially in Yogyakarta. Timoho wood has a beautiful pattern called pelet and is used as a raw material for keris sheath. In Javanese culture, the keris is a masterpiece culture that is used as a weapon, spiritual object and complementary traditional events such as marriage. In Yogyakarta, Timoho trees are difficult to find, currently, so that plant propagation in a generative way also has difficulty due to scarcity of seeds. Therefore, it is necessary to conduct Timoho propagation research through vegetative methods. The purpose of this study was to determine the relationship between the origin of stem cuttings from three Timoho mother trees and the stem section (base, middle, and end) to the success of Timoho stem cuttings. Stem cuttings come from three Timoho trees in the Arboretum of the Center for Forest Research and Development of Forest Biotechnology and Tree Improvement Yogyakarta. The research method used a nested experimental design using 3 mother trees and 3 stem parts (base, middle and end) which were nested in the mother tree. The characters observed were percentage of shoots, number of shoots, length of shoots, and number of leaves. The results showed the percentage of live cuttings varied from 10.9-60.0%, number of shoots 1-7 pieces, number of leaves 3-26 strands and length of shoots 2.00-17.7 cm. The mother tree treatment has a significant effect on the percentage of sprouts and shoot length, while the cuttings material has a significant effect on the length of shoots at the cuttings measurements of the age of 2 months since planted in polybags.

Abstract

The tree improvement research of nyamplung has entered the selection stage at the individual levels having high quality and oil yield properties. In order to maintain the superiority of this characteristics, a proper vegetative propagation techniques is required to multiply selected trees.The purpose of this study is to determine the effect  of cutting materials from sprouts on seedlings and mother trees. The study was arranged in a completely randomized design with factorial pattern. The factors tested were cutting materials (namely sprouts on seedlings and on the mother tree branches) and application of growth hormone types (control, pasta and  powder). The results showed that the survival rates and the growth of cuttings from seedlings and mother trees  were relatively similar. However, the rooting percentages and the growth of cuttings were significantlyinfluenced by the interaction between the two factors. The survival rates of shoot cuttings varied from 51.92 to 82.30% and rooting percentages range from 32 to 70%. The best result of rooting percentage and shoot cuttings growth were obtained at shoot cuttings from seedlings with growth hormone in the pasta type.

Abstract

Nyamplung (Calophyllum inophyllum) is a potential type of non-timber forest product (NTFP) with high oil yield which is useful as an alternative renewable energy sources and herbal medicine-cosmetics. Result of population selection level in Java Island have been used to build Provenan Seed Stand (PSS) nyamplung in KHDTK Wonogiri (Central Java) as an improved seed source with high oil yield and fruit productivity. Seed become nyamplung part that is used as oil raw material which is strongly influenced by flowering and fruiting period. Information on flowering fruiting ability and period is needed to support the availability of raw materials in a sustainable supply for the nyamplung oil industry. Seed become nyamplung part that is used as oil raw material which is strongly influenced by flowering and fruiting period. Information on flowering fruiting ability and period is needed to support the availability of raw materials in a sustainable supply for the nyamplung oil industry. Observation of flowering and fruiting period focused on 465 individual trees in nyamplung PSS at KHDTK Wonogiri through monthly monitoring by calculated flowering fruiting individualtree during 5 years (2014-2018). The results showed that the flowering period of nyamplung in TBP Wonogiri varied during 2014-2018. Flowering and fruiting occurs almost throughout the year. However, the peak of flowering and fruiting occurs mostly in March-August (end of the rainy season to the middle of dry season). In general, the trend of flowering and fertilization increased in 2014-2016, then decreased in 2017-2018, which is thought to be influenced by the higher canopy density. The environmental factor that most influences flowering is number of rainy days, while fertilization of TBP was strongly influenced by temperature. The management of TBP require future action such: second thinning, top pruning, application of fertilizers and hormones to stimulate flowering, and further detailed observations of flowering fruiting stage and its interaction with microclimate.
