Abstract

Research was conducted on a banana cultivar of Rajabulu/AAB inside the green house. This research was aimed to study the effect of rhizobacteria and the ability of in vitro bacterization to prevent FOC. This study was conducted using split plot design. The main plot was rhizobacteria treatments (P. fluorescens ES-32, B. subtilis SB-3, a mix of both types and without bacteria), sub plots consist of in vitro (2 weeks and 1 week prior to application) and in vivo (during acclimatization) bacterization. All treatments were repeated 3 times, each consist of 7 polibags. The result of rhizobacteria treatment (B. subtilis SB3 or P. fluorecens ES32) was able to reduce the Disease Severity (Rhizome Discoloration) caused by Fusarium oxysporum f.sp cubense (FOC). The incorporation of mixed rhizobacteria provided significant effect suppressing the infestation of FOC. The application of mix bacteria was better than single treatment.Keywords: B. subtilis, P. fluorecens, rhizome discoloration, fusarial wilt, suppressing

Abstract

ABSTRACTContamination of yellow sap (GK) in the mangosteen fruit leads to low quality of the mangosteen fruit. GK contamination occurs because the cell walls of the fruit is weak due to lack of calcium (Ca) and boron (B). Ca and B plays a role in maintaining the integrity of the cell wall. The study aimed to get the best treatment of dose and the time of application of Ca and B in controlling the contamination of GK on the aryl and mangosteen pericarp. This study used a nested design with 3 factors. First factor was study site, consisting of Cigudeg, Citeureup and Cikembar. The second factor was combination dose of fertilizer, consisting of control (without Ca + B), 1.6 kg Ca tree-1 + 1.553 g B tree-1, and 3.2 kg of Ca tree-1 + 1.553 g B tree-1. The third factor was time of fertilizer application, consisting of anthesis, stadia 1, and anthesis + stadia 1of fruit development. Result of the study showed that location which produced the best fruit was Cikembar where GK on aryl was 22.49% and on pericarp was 29.51%. A dose of 1.6 kg Ca tree-1 + 1.55 g B tree-1 and 3.2 kg Ca tree- 1 + 1.55 g B tree-1 were equally well in reducing GK contamination In aryl (19.91%) and pericarp (28.86%) compared to treatment without Ca and B which showed percentage of GK contaminated fruit on aryl was 50.00% and on pericarp was 56.46%. Ca and B application time was the best at stage 1, which lowered the percentage of GK contamination in aryl (40.44%) and pericarp (27.10%). Ca and B did not affect the physicochemical qualities including diameter, weight, hardness, total soluble solid, total titratable acidity of mangosteen fruit in three study sites.Keywords: fertilization, immobile nutrient, cell wall, pericarp, yellow sap.ABSTRAKCemaran getah kuning (GK) pada buah manggis menyebabkan rendahnya mutu buah manggis.

Abstract

ABSTRACTSiam tangerine peel is green when harvested. Degreening technology by ethylene can improve the citrus peel color becomes uniformly orange. Degreening is a process to break down green pigment (chlorophyll) on citrus peel chemically and form the orange color (carotene) without affecting internal quality of fruit. The purpose of this research was to determine the effect of ethylene concentration and ethylene exposure duration to bring out the color on Siam tangerine from Banyuwangi. Ethylene 0, 100, 200 ppm was injected into the box containing 2.8 kg citrus and was exposed to the cooling chamber with a temperature 18 0C for 24 hours ethylene + 48 hours without ethylene, 48 hours ethylene + 24 hour without ethylene and 72 hours ethylene. Ethylene exposure was conducted using multiple shots method. After exposure, tangerines were put at room temperature condition. Observations were conducted every two days: (a) non-destructive observation conducted using color reader to determine the color changes; (b) destructive observations for measuring chlorophyll and carotenoids content and physico-chemical changes i.e. the hardness, soluble solid content, titratable acidity and vitamin C. The results showed that the best combination was 200 ppm ethylene concentration for 48 hours ethylene exposure. This degreening technique altered the Citrus Colour Index (CCI) value from -1.60 to be 6.50, changed the tangerines into a bright orange. Degreening did not give negative impact on internal quality.Key words: carotenoid, chlorophyll, citrus color index, cooling chamber, tropical citrus         ABSTRAKWarna kulit buah jeruk siam saat dipanen umumnya hijau.
