Potential of Wood Vinegar in Enhancing Fruit Yield and Antioxidant Capacity in Tomato
Hiyasmin Rose L. Benzon,Sang Chul Lee 한국자원식물학회 2016 한국자원식물학회지 Vol.29 No.6
Tomatoes are considered as one of the main components of daily meals in most households. Thus, it is important to invest in studies enhancing their yield and nutritional value. The study evaluated the effect of wood vinegar (WV) on tomato under greenhouse conditions. Data on fruit number, fruit weight, and plant height were recorded. Total phenolic content (TPC) and antioxidant activity of tomato were determined using the Folin-Ciocalteu reagent and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, respectively. FRR-CF+500x-WV significantly increased the fruit number (86.11%) and fruit weight (81.78%) over the control. Results were comparable to HRR-CF+250x-WV, indicating that conventional fertilizer and WV may have synergistic effect on each other. TPC and scavenging effect on DPPH radical was improved by 250x-WV application. The increase in the phenolic compounds can be attributed to WV as a direct source or as a factor triggering the plants to produce more secondary metabolites with the purpose of increasing natural defenses. The significant effect obtained by applying the full recommended rate of conventional fertilizer on the carotenoid content was due to the availability of the major nutrients needed by the plant. Correlation analysis showed that carotenoids have negative correlation with TPC and DPPH. However, TPC and DPPH showed that these are positively correlated with each other. Tomatoes are excellent source of antioxidants associated with the reduction of some human diseases and improved health. The results provided evidence that WV alone and/or its combination with conventional fertilizers has favorable effects on the quality of tomato.

<P><B>Abstract</B></P> <P>The neutron-rich isotopes of palladium have attracted considerable interest in terms of the evolution of the N = 82 neutron shell closure and its influence on the <I>r</I>-process nucleosynthesis. In this Letter, we present the first spectroscopic information on the excited states in <SUP>125</SUP>Pd<SUB>79</SUB> and <SUP>127</SUP>Pd<SUB>81</SUB> studied using the EURICA <I>γ</I>-ray spectrometer, following production via in-flight fission of a high-intensity <SUP>238</SUP>U beam at the RIBF facility. New isomeric states with half-lives of 144(4) ns and 39(6) μs have been assigned spins and parities of ( 23 / <SUP> 2 + </SUP> ) and ( 19 / <SUP> 2 + </SUP> ) in <SUP>125</SUP>Pd and <SUP>127</SUP>Pd, respectively. The observed level properties are compared to a shell-model calculation, suggesting the competition between proton excitations and neutron excitations in the proton-hole and neutron-hole systems in the vicinity of the doubly magic nucleus <SUP>132</SUP>Sn.</P>
