Assessment of inter simple sequence repeat (ISSR) technique in mangosteen (Garcinia mangostana L.) grown in different Sumatra region

Posted on Posted in Publikasi Internasional, Publikasi Internasional, Year 2010, Year 2010

Abstract. Inter-simple sequence repeat (ISSR) markers were used to examine the level of genetic diversity in mangosteen. Twenty three accessions of the Garcinia mangostana collection from Sumatra region were screened for ISSR markers. Eleven random ISSR primers were chosen to differentiate the investigated accessions. The primers generated 72 bands of which 42 (58%) were polymorphic […]

Morphological variability of apomictic mangosteen (Garcinia mangostana L.) in Indonesia: Morphological evidence of natural populations from Sumatra and Java

Posted on Posted in Publikasi Internasional, Publikasi Internasional, Year 2010, Year 2010

Summary. Indonesia is one of the most important mangosteen producing countries whose the growing areas are scattered on almost all of the islands. Mangosteen variability was observed based on field expeditions from 1992 to 2005. The data were collected on morphological observations on mangosteen production centres in West Sumatra, Riau, Jambi, South Sumatra, Bengkulu, Bangka/Belitung, […]

Comparison of static-mixer and blade agitator reactor in biodiesel production

Posted on Posted in Publikasi Internasional, Publikasi Internasional, Year 2010, Year 2010

Abstract. One of the difficulties faced in the current technology for biodiesel production is the requirement for rigorous mixing of methanol with the feedstock oil in the reactor. Utilization of blade mixer is limited by the immiscible state of those substances. This research is devoted to the assessment of static-mixer utilization in a transesterification reactor […]

Screening of pepper accessions for resistance against two thrips species (Frankliniella occidentalis and Thrips parvispinus)

Posted on Posted in Publikasi Internasional, Publikasi Internasional, Tahun 2011, Tahun 2011

Abstract. Thrips are damaging pests in pepper worldwide. They can cause damage directly by feeding on leaves, fruits or flowers, and also indirectly by transferring viruses, especially tomato spotted wilt virus (TSWV). Although thrips are among the most damaging pests in pepper, until now there is no commercial variety with a useful level of resistance […]

USE OF YEAST ANTAGONIST CRYPTOCOCCUS TERREUS TO CONTROL PETAL BLIGHT OF DENDROBIUM CAUSED BY CURVULARIA PALLESCENS

Posted on Posted in Publikasi Internasional, Publikasi Internasional, Year 2013, Year 2013

Abstract. This research sought to obtain a superior yeast antagonist as a biological control agent of petal blight disease of dendrobium, to study the mechanism involved in biocontrol activity of yeasts and to study the effectiveness of yeast antagonists under field conditions. Five yeast isolates were investigated for their antagonistic activity in-vivo on detached petals, […]
