As investigation was carried out into the chemical and sensory assessment of canned satsuma mandarin during long-term storage. The carbonyl compounds as 2,4-dinitrophenyl hydrazones were separated by silica gel TLC. 3-Deoxyglucosone, 3-deonypentosone, 5-hydroxymethyl furtural (HMF) and furtural were identified. The content of HMF as a dominant carbonyl compound increased noticeably during storage at higher temperatures. Canned satsuma mandarin which contained HMF above 50 ug/g gave inferior quality in sensory evaluation. This HMF level was achieved by three to four years storage at ambient temperature. These results demonstrate that HMF is good as a quality index of canned satsuma mandarin. Furthermore, the amount of d-limonene decreased significantly during storage, whereas furtural increased. This result demonstrates that determination of these volatiles is also available for quality assessment. |

In oat production, tillering persistence is the determinant of one important yield component, namely the number of panicles. This process is highly infl uenced by the inter- and intraspecifi c interactions of the agroecosystem, which in turn depend on agronomic practices. The hypothesis of this research is that nitrogen does not increase oat tolerance to negative interference from trees, so oat tillering persistence in grain production remains un-modifi ed by nitrogen at distances relative to the eucalyptus tracks, within the alley cropping agroforestry system (ACS). Thus, nitrogen should not be used to increase oat yield potential in these systems. The objective of this study was to determine how the tillering persistence for grain production and oat (Avena sativa L. cv. ‘IPR 126’) tiller traits were infl uenced by nitrogen levels (12 and 80kg N ha-1) at fi ve equidistant positions between two adjacent eucalyptus (Eucalyptus dunnii Maiden) double line tracks [20m (4mx3m)] in ACS and traditional no-till agriculture in subtropical Brazil. The experiment was conducted in a split-block randomized block design with four replicates. The goal was to evaluate the oat phytomass, tiller-to-main shoot phytomass ratio, tillers per main shoot, grain yield and tiller-tomain shoot grain yield ratio. The oat tillering persistence for grain production is dependent on different nitrogen levels at distances relative to adjacent eucalyptus tracks and therefore, different nitrogen levels should be used in those areas, to improve oat yield potential inside ACS in subtropical Brazil.
