Criteria For Selection

A problem encountered in plant breeding process to determine bean color quality of fine-flavor cocoa is a long selection period. Preliminary results indicatedthat the fine-flavor cocoa has a low color reflectance than bulk cocoa. The objectiveof this study is to find more applicable and easier method to do the early detectionof fine-flavor cocoa on the breeding population. Detection of the leaf color haracteristics was done by chromatographic and spectrophotometry analysis. hromatographic analysis was carried out in Kaliwining Experimental Station, IndonesianCoffee and Cocoa Research Institute using complete random design consistedof two types of cocoa; fine-flavor (10 clones) and bulk cocoa (10 clones). pectrophotometric analysis was conducted at Ma Chung University, Malang, East Java.Four clones of bulk cocoa and six clones of fine flavor cocoa were used in thisanalysis. The results of the study showed that the flush color characteristics of thefine-flavor cocoa were different from the bulk cocoa characteristics as shown bythe differences in the value of L*, b* and anthocyanin content. Flush characteristic s ofthe fine-flavor cocoa had brighter color, more toward green with higher yellowlevel, while the bulk cocoa had darker flush, red and lower yellow level. Thecolor parameter of L* and b* had a higher genetic variation compared with theenvironment variation. However, the parameter a* had a higher environmental variation compared with genetic variation. Grouping of fine-flavor cocoa and bulk cocoacould be done through the detection of flush anthocyanin content, when tendencyof flush anthocyanin content on fine-flavor cocoa was lower than bulk cocoa.The detection of flush color particularly L* and b* parameters through hromatographic analysis and anthocyanin content through spectrophotometric analysismay be used as a criteria for selection the fine flavor cocoa on seedling phase.

This study was carried out to determine the effects of ultraviolet-B (UV-B) and LED light on improving postharvest quality of 0900 Ziraat cherry fruits. In the present study, UV-B treated to cherry fruits 10, 20, and 40 min, and then stored dark conditions. On the other hand, the blue (M), red (KR) and ultraviolet-A (UVA) LED light had applied to fruit during storage, continuously. Fruits without application were used as a control. Cherry fruits were stored at 4±1°C temperature with 85-90% RH for 35 days. As a result of the study, the best treatment in terms of increasing the TSS/TA rate (19.3), fructose (5.27%), glucose (6.22%), total soluble phenol (170.16 mg/100 mL CAE) and anthocyanin content (12.11 mg/kg FW), red color, and taste quality (4.63) of fruits was UVB20. It has also been seen that the KR treatment could be used to reducing the titratable acidity content, and increase the amount of fructose, total soluble phenol. The UV-A LED treatment is particularly significant in reducing weight loss, and providing in the fruit stalk remains green. Also, the treatments of both UVB and LED improved the color quality of cherries by increasing brightness, darkening red color, and protection of anthocyanins, whereas increased the EL. As a result, it might be concluded that the UVB20 (5.95 kJ / m2s) treatment was the best and usable treatment to maintaining both biochemical and taste quality cherry fruits during cold storage.

Quality of Carrots Grown for Processing as Affected by Nitrogen Fertilization and Harvest TermIn 2007-2008 the effect of nitrogen fertilization and harvest term on quality of two carrot cultivars was investigated. The field experiment was carried out in Żelazna Experimental Station of Warsaw University of Life Sciences. Karotan F1and Trafford F1cultivars, commonly grown for juice industry, were the objects of the experiment. Carrot seeds were sown at the beginning of May. Nitrogen fertilization was applied in five rates, ranged from 0 to 120 kg·ha-1and in two terms — before sowing and in the middle of growing season. Roots were harvested in three terms: mid-September, mid-October and the first decade of November. After harvest there were determined: nitrates (NO3) content in carrot roots and juice, soluble solids, colour parameters of juice in CIE L*a*b*system. The dose and the term of nitrogen fertilization influenced nitrates content in carrots, and the highest NO3concentration was found in carrots fertilized with 120 kg·ha-1of N before sowing. Karotan showed higher nitrates accumulation than Trafford. The content of nitrates in the roots was markedly higher than in carrot juice. Nitrates content in carrots decreased with delaying of harvest time, in opposite to soluble solids content. Soluble solids content and colour parameters of carrot juice were not affected by nitrogen fertilization, but the lowest L*, a*and b*values were observed at the last term of harvest.

Light causes damage when it is absorbed by sensitive artwork, such as oil paintings. However, light is needed to initiate vision and display artwork. The dilemma between visibility and damage, coupled with the inverse relationship between color quality and energy efficiency, poses a challenge for curators, conservators, and lighting designers in identifying optimal light sources. Multi-primary LEDs can provide great flexibility in terms of color quality, damage reduction, and energy efficiency for artwork illumination. However, there are no established metrics that quantify the output variability or highlight the trade-offs between different metrics. Here, various metrics related to museum lighting (damage, the color quality of paintings, illuminance, luminous efficacy of radiation) are analyzed using a voxelated 3-D volume. The continuous data in each dimension of the 3-D volume are converted to discrete data by identifying a significant minimum value (unit voxel). Resulting discretized 3-D volumes display the trade-offs between selected measures. It is possible to quantify the volume of the graph by summing unique voxels, which enables comparison of the performance of different light sources. The proposed representation model can be used for individual pigments or paintings with numerous pigments. The proposed method can be the foundation of a damage appearance model (DAM).

Muscadine Grape

Biochemical juice attributes and color-related traits of muscadine grape genotypes have been investigated. For this study, 90 muscadine genotypes, including 21 standard cultivars, 60 breeding lines, and 9 Vitis x Muscadinia hybrids (VM), were evaluated. The biochemical properties of total soluble solids (TSS), titratable acidity, and TSS/Acid (T/A) ratio showed modest diversity among genotypes with a range of 10.3 °Brix, 2.1 mg tartaric acid/L, and 4.6, respectively. Nonetheless, the pH trait exhibited a tight range of 0.74 among the population with a minimum and maximum pH of 3.11 ± 0.12 and 3.85 ± 0.12. Color-related traits showed more deviation between individuals. Total anthocyanin content (TAC), luminosity index (L*), hue angle (h°), and chroma index (C*) displayed a range of 398 µg/g DW, 33.2, 352.1, and 24, respectively. The hierarchical clustering map classified the population into two large groups of colored and non-colored grapes based on L* and h°, suggesting the predominance of these two characters among the population. The colored berries genotypes clade was further divided into several sub-clades depending on C*, TAC, and TSS levels. The principal component analysis (PCA) separated the four-color characteristics into two groups with a negative correlation between them, L* and C* versus TAC and h°. Further, PCA suggested the positive influence of acidity in enhancing the different nutraceutical components. Despite the nature of anthocyanins as a member of phenolic compounds, a lack of significant correlation between TAC and nutraceutical-related traits was detected. The dissimilatory matrix analysis highlighted the muscadine individuals C11-2-2, E16-9-1, O21-13-1, and Noble as particular genotypes among the population due to enhanced color characteristics.

The Impact

The study aimed to evaluate the effects of process parameters (time and raw material weight (RMW)) of conventional (boiling for 10–45 min) and microwave-assisted (2–8 min) aqueous extraction on the color quality (i.e., lightness (L*), chroma (C*), and hue (H°) of anthocyanin –based colorants of red and Inubi sweet potato (Ipomoea batatas L.) leaves. Using response surface methodology, it was found that RMW and boiling time (BT) and microwave time (MT) generally had a significant (p < 0.05) effect on the color quality of the extract from both extraction methods. The effects were found to vary depending on the extraction method and variety of the leaves used. Both extraction methods produced a brown to brick-red extract from the Inubi variety that turned red-violet to pink when acidified. The red sweet potato leaves produced a deep violet colored extract that also turned red-violet when acidified. It is recommended that the anthocyanin content of the extracts be measured to validate the impact of the methods on the active agent. Nevertheless, the outcomes in this study may serve as baseline data for further studies on the potential of sweet potato leaf colorants (SPLC) as a colorant with functional properties.

The aim of this research is to investigate related effect of dyeability to linen textiles related to different printing parameters. The study investigated the change in color characteristics when printing on linen fabrics with an inkjet MIMAKI Tx400-1800D printer with pigmented TP 250 inks. The dependence of color reproduction on linen fabrics on the number of print head passes, number of ink layers to be coated, linen fabric density, and different types of linen fabric was investigated. All this affects the quality of print and its mechanical properties. The change in color characteristics on different types of linen fabrics was determined experimentally. We determine at which print settings the most accurate color reproduction can be achieved on different linen fabrics. The difference between the highest and the lowest possible number of head passages was investigated. The possibilities of reproducing different linen fabric colors were determined.

Hatchery and culture technology of Humpback grouper has been developed. However,  sometimes it is still found constraint in sedd production and caused instability of production due to failure by many factors. Breeding program become necessary to provide seed with high quality and good genetic variation. Quantitative characteristic selection is one of breeding program to improve productivity in grouper aquaculture. The aim of this research was to produce good phenotyphic and genotypic quality of Humpback grouper candidate broodstock. Selection of Humpback grouper F1 and F3 was done based on quantitative characteristic (body length and weight) and genotyphic characteristic by using ramdom amplified polymorphism DNA (RAPD) method.  The results of conventional selection were found candidate broodstock of Humpback grouper F1 and F3 with body weight range from 170-210 g and 160-170 g consecutively.  Heterozygosity values of Humpback grouper analized by RAPD of F1 and F3 were 0.7940 and 0.7749 consecutively and it was not significantly different. This value emphasis that population of this F3 Humpback grouper was still good to grow for broodstock. Keywords: genetic variation, humpback grouper, F1, F3.
