Abstract

Gall rust disease caused by Uromycladium falcatarium fungus is one of sengon (Falcataria moluccana) diseases in the nursery and field.  The purpose of this study was determining the effect of seed sources and controller type against the resistance of sengon seedlings from infection of  Uromycladium falcatarium in the nursery. The research design used a factorial completely randomized design with two 2 factors i.e sources of the seed (A1 = seed from the endemic area of gall rust/Kediri; A2 = seed from non-endemic of gall rust/Cianjur) and the type of cotrollers (B1 = no treatment  l; B2 =  biological fertilizer of Plant Growth Promoting Rhizobacteria (PGPR) (5 g.l-1); B3 = Biofungicide (5 g.l-1); B4 = biofungicide of soursop leaf extract (10 g.l-1); B5 =mancozeb (2 g.l-1). Each treatment combination consisted of 10 seedlings repeated 4 times. The observation variables were the disease incidence and intensity, the number of teliospores and thickness of the epidermal cell wall. The results of the study showed that the interaction of seed sources and type of controller affected the number of teliospores and thickness of the epidermis. The lowest number of teliospores (6.48 teliospores) was found in seedlings from non endemic  gall rust areas with the controller of soursop leaf extract. The thickest epidermal cells (5.43 μ - 5.84 μ) were produced from seedlings from gall rust-free area with PGPR solution controller, soursop leaf extract and mancozeb. The disease intensity in seedlings originating from gall-free areas (3.5 percent) is lower than endemic areas (5.2 percent).  PGPR and mancozeb were effective to the infection of fungus because the disease incidence and  intensity were low after the 3rd control stage.

Abstract

Teak wood is the superior wood for carpentry, and the need for carpentry continues to increase in Indonesia. It has prompted various efforts to increase teak production, both in state forests and non-state forests. One of the efforts to increase teak production is using advanced science and technology, superior teak seedlings from mutation breeding. This study aims to describe smallholder's perception of the demonstration plot of Muna Teak from mutation breeding in the Cariu Private Forest, Bogor Regency. The research used two methods: Focused Group Discussion and semi-structured interviews by questionnaires. For the analysis, the study used the perceptual process framework) to explore the data from the two methods and present it descriptively. The result shows that smallholders had a good perception toward the mutation breeding Muna Teak demonstration plot. Smallholders can carry out intercropping (agroforestry) activities in the demonstration plot and increase their knowledge of forestry plant cultivation, especially teak. The activity provides an opportunity for smallholders to improve their welfare.
