Abstract. Thrips is one of the most damaging pests in pepper (Capsicum). Resistance to thrips was identified in Capsicum annuum. This study was aimed at the elucidation of the genetic background of thrips resistance in Capsicum through QTL mapping. The QTL analysis was carried out for Frankliniella occidentalis resistance in an F2 population consisting of […]
Abstract. Starch and soluble solid content in papaya are an important parameter for measuringthe maturity of fruit after harvesting. In this work, the application of near infrared (NIR) spectroscopy in measuring starch and soluble solid content in papaya wereevaluated. Samples of papaya were harvested at 135, 131, 128, 121 and 114 days after anthesis. NIRFlex […]
Abstract. Indonesia is one of the megabiodivesity, which is rich with germplasms including tropical fruit. Snake fruit (Salacca spp.) is a native fruit of Indonesia with a scaly peel and sweet-tart taste. The genetic diversity of 17 accessions of Indonesian snake fruit was resolved using the Random Amplified Polymorphic DNA Polymerase Chain Reaction with 5 […]
Abstract. Near infrared spectroscopic (NIRS) techniques have shown promise as rapid and non-destructive tools to evaluate the internal quality attributes of fruits. The objective of this work were to develop a calibration model for prediction soluble solids content (SSC) and acidity in ‘Gedong Gincu’ mango using NIRS and to analyze the effects of different preprocessing […]
Abstract. Internal and external qualities of mangoes during storage were evaluated by hyperspectral spectroscopy. Green mature mangoes were harvested in Okinawa Prefecture, Japan, and stored for 14 d at 27℃ [relative humidity 90%]. Spectral reflectance (380 _ 1000 nm), anthocyanin concentration, chlorophyll concentration in skin, and soluble solid content (SSC) in flesh were measured during […]
Abstract. The leaf trichome morphology of 19 Durio kutejensis (lai) landraces was studied. The observation of cross- and paradermal sections of D. kutejensis leaves showed that all landraces have glabrous leaves on the adaxial surface, while their abaxial surfaces are covered by six trichome types, one glandular (one- or two-celled stalks with a spheroid multicellular […]
