It is grown in Southeast Asia, but its distribution there remains unknown. We conducted literature, specimen, field, and market surveys of C. chinense in Indonesia to investigate its introduction into Indonesia and to determine its current distribution. One dried specimen collected in 1912 and stored as Capsicum sp. appears to be either C. frutescens or C. chinense. An illustration of C. frutescens in Ochse (1931), which actually appears to be C. chinense, suggests that C. chinense may have been introduced into Indonesia before World War II; however, the distribution of C. chinense in Southeast Asia remains very limited to this today. In Indonesia, C. chinense is distributed widely on at least the three major islands of Java, Kalimantan, and Sulawesi with several morphologically different fruit types; it is used as an ornamental plant as well as a spice. Four species of the genus Capsicum, including C. annuum, C. frutescens, C. pubescens, and C. chinense, are distributed in Indonesia, which suggests that Indonesia has more genetic resources and more potential to breed species of Capsicum than other countries in Southeast and East Asia.","PeriodicalId":118800,"journal":{"name":"Tropical agriculture and development","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134096139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, determination of the fl ux from the decomposition process is usually over-estimated because the total CO2 fl ux calculation includes root respiration. We clarified this issue addressing the following aims: (i) to study the relation of oil palm root distribution in peat soils to the fl ux and (ii) to estimate the relative contribution of root respiration and peat decomposition to the total CO2 fl ux. The study was conducted between January and June 2012. In the research area, three transects were established perpendicular to drainage channels, where nine14- year-old oil palm trees were selected and used as observation sites. Eight closed chambers were established as observation points at each site. We measured CO2 fl ux at each point using an Infra Red Gas Analyzer (IRGA). Root and peat samples were collected from each observation point to measure root density and analyze peat chemical properties. Our results showed that the pHH2O and nutrient content of P, K, Ca and Mg in the peat soils significantly increased of CO2 fl ux. Oil palm roots at depths of 0-15 and 15-30 cm nearest the tree showed the highest density, while root densities gradually decreased with increasing distance from the tree. CO2 fl ux in the peat soils nearest to the tree were highest at 0.44 ± 0.23 mg CO2 m- 2 sec- 1 (or 137.7 ± 73.4 t CO2 ha- 1 yr - 1 ). CO2 fl ux significantly decreased with increasing distance from the tree, showing the lowest value of 0.10 ± 0.04 mg CO2 m- 2 sec- 1 (or 30.67 ± 12.4 t CO2 ha - 1 yr - 1 ). We conclude that the CO2 fl ux was derived from peat decomposition and root respiration. Using the integral equation approach, the relative contribution of root respiration and peat decomposition was 74 and 26%, respectively to the total CO2 fl ux.","PeriodicalId":118800,"journal":{"name":"Tropical agriculture and development","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115301447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
