Abstract

Mangosteen (Garcinia mangostana Linn.) dubbed as “finest fruit of the world”, has potential for both domestic market and export. However, this potential is threatened by low fruit quality caused by production of yellow latex and fruit scarring. The research objective was to obtain technology to reduce yellow latex and control Scirtothrips dorsalis, a pest that causes scarring on mangosteen. A randomized block design with four treatments and 14 replications was used in this research. Significant differences among the treatments were calculated using the Honestly Significant Difference (HSD) test. The results showed that treatment of drip irrigation system in combination with removing weeds under the canopy (A) or removing weeds followed by minimum tillage under the canopy (B) or removing weeds then covering with rice hay mulch under the canopy (C), where N, P, K, Ca, Mg fertilizer and yellow fluorescent sticky trap were applied could reduce scarring intensity and percentage of yellow latex on the fruit peel. However, the treatments did not significantly impact fruit diameter or percentage of yellow latex inside the fruit. Nevertheless, treatment C improved mangosteen quality by as much as 67.79% fulfilling export standard requirements.Keywords: Mangosteen, quality improvement, drip irrigation, yellow fluorescent sticky trap

Abstract

Avocado is a cross-pollinated plant that has many variations of morphology. The study aimed to classify avocado accession based on morphological characters and to evaluate avocado accession based on predefined idiotype. The research has been conducted in January and February 2015 in three sub-districts in Solok District, representing lowland, middle and highland. The characters observed were morphological characters, both qualitative and quantitative in accordance with Descriptors for Avocado (IPGRI 1995). The calculation of genetic distance between accessions was done by Gower method. The selection of idiotypes has been done by collecting information on consumer preferences on the characteristics of avocado from fruit shops, fruit traders in traditional markets, farmers, and consumers. The results showed that 21 avocado accession of Solok regency can be grouped into two main groups, namely Idal 3 avocados and 20 other accessions. The coefficient of dissimilarity between the two groups is about 45% or with a similarity of 55%. Accessions that have many superior characters are the accession of Idal-1, Zainal and Asni-2.
