Abstract

The diversity of Mangivera caesia Jack (Balinese name: wani) in Bali was quite high. Based on the morphological characters of the fruit, 22 cultivars had been explored in the previous research (Rai et al., 2008). One of the most superior cultivar among those and very potential to be commercially developed was seedless wani (M. caesia Jack. var. Ngumpen Bali). The cultivar had specific properties that were not possessed by the others. Ninety (90) % of the total fruits produced were seedless, while the remaining (10%) has small seed. Beside that, this seedless cultivar had thick flesh, very attractive skin color (glossy yellowish green), uniformity on the size and shape of fruits, a distinctive aroma, sweet, tasty, and highly nutritious. The results of RAPD analysis of 10 wani cultivars grown in Bali showed that this seedless cultivar (Ngumpen) was grouped in to different cluster, a part from others. In comparison with 4 seeded cultivars of wani, Ngumpen cultivar had a similar nutrient content, however, it had greater fiber and a greater percentage of edible part. We concluded that the Ngumpen cultivar was a specific and unique germplasm so that should be preserved and protected.

Abstract

Cultivation of organic snake fruit in Bali which is done on dry land with the irrigation depends on rainfall and the fertilization generally only uses uncertain amount of fallen leaves, it reduces the productivity, quality, and continuity of fruit production over time. In rhizosphere of snake fruit there are various types of indigenous endomycorrhiza that potentially can be developed as biofertilizer, but as a biofertilizer, the low number of spores population for inoculum becomes a limiting factor in using indigenous endomycorrhiza. The effort that can be done are to propagate the spores by giving water stress treatment. This study aimed to obtain the best rhizosphere location of snake fruit as the source of spores and the level of soil water content to multiply the spores. The research was conducted in the green House, Farm Station, Agriculture Faculty, Udayana University at Jalan Pulau Moyo, Denpasar, from October 2017 to January 2018. The spore propagation used nested experiment with Randomized Block Design patterns. The treatments were rhizosphere location as the source of indigenous endomycorrhizas spore consists of three levels (Bebandem District Karangasem Regency, Payangan District Gianyar Regency, and Pupuan District Tabanan Regency) and soil water content consists of three levels (100%, 70%, and 40% field capacity). The results of the research showed that the source of indigenous endomychorrizae from snake fruit rhizosphere in Payangan District gave the highest number of spores found and the highest percentage of the spore increase after propagation. While in the soil water content treatments, the highest number of spores found and the percentage of the spore increase after propagation were obtained at soil water content of 40% field capacity. The percentage of root infections from different sources of indigenous endomychorrhizae and different levels of soil water content is same i.e 100%.
