<p>‘Maha Chanok’<strong> </strong>mango is an economic fruit crop widely cultivated commercially throughout Thailand. By nature, mango fruit has a rather limited storage life after harvest. 1-methylcyclopropene (1-MCP) has been accepted as a commercial substance to improve several fruit qualities. The objective of this research was to study the effects of 1-MCP on the external postharvest qualities and storage life on the ‘Maha Chanok’ mango fruit. The experiment was laid out in a Completely Randomized Design with three replicates, ten fruits per replicate. Mango fruit was fumigated with 1-MCP at three concentrations (1000, 1250, or 1500 nl l<sup>-1</sup>) and three fumigation periods (12, 18, or 24 h), compared with the control fruit. After treating, all treatments were stored under ambient temperature (27 °C, 80%R.H.). The following determinations were made every two days for assessment of fruit weight loss, firmness, chlorophyll content, decay incidence, and storage life. The results showed that fruit treated with 1500 nl l<sup>-1</sup><strong> </strong>1-MCP for 24 h had the maximal fruit firmness. For chlorophyll content, the results showed that fruit-treated with 1500 nl l<sup>-1</sup><strong> </strong>1-MCP for 12 h could effectively retain the highest chlorophyll contents. Furthermore, both the lowest fruit decay and the longest storage life of 12 days were achieved from the fruit treated with 1000 nl l<sup>-1</sup><strong> </strong>1-MCP for 12 h.</p>

ABSTRACT The objective of this study was to verify the efficiency of two portable chlorophyll meters (Minolta SPAD® 502 and Falker ClorofiLOG® 1030) in assessing the nutritional status of wheat plants, correlating the indices from the devices and the direct determination of chlorophyll content with the concentration of nitrogen (N) in the plant. The experiment was conducted in a greenhouse, in pots with 5 dm3 of Oxisol, in a completely randomized design, with six N doses (0, 80, 160, 240, 320 and 400 mg dm-3) and five replicates. At 47 days after emergence, the readings of SPAD and Falker indices and the quantification of chlorophyll content and N concentration in wheat plants were performed, as well as analysis of variance and correlation test, both at 0.05 probability level. The chlorophyll meters Minolta SPAD® 502 and Falker ClorofiLOG® 1030 do not differ with respect to the indirect determination of chlorophyll in wheat plants. The Falker chlorophyll index was statistically equal to the chlorophyll content. Indirect chlorophyll indices and chlorophyll content showed a high correlation with the N concentration in the plant.

Level of anthocyanin content in flush is different between fine flavor cocoa and bulk cocoa. This study was aimed to determine the potential of anthocyanin and chlorophyll content in flush as one of the selection indicator for fine flavor cocoa. Flush sampling was carried out at Cocoa Germplasm Collections in Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, while anthocyanin and chlorophyll analysis was conducted at Laboratory of Ma Chung Research Center for Photosynthetic Pigments, Ma Chung University, Malang.The research utilized a completely randomized design consisted of four genotypes of fine flavor cocoa, namely DR 2, ICCRI 02, DRC 16, PNT 16 and five genotypes of bulk cocoa, namely Sulawesi 1, MCC 01, MCC 02, KW 617 and PA 191.Each treatment was repeated three times. Anthocyanin and chlorophyll content in flush was measured. Anthocyanin analysis was done by destructive methods, while flush color was observed based on Munsell Color Chart for Plant Tissues Data analysis used orthogonal contrast, multivariate and simple correlation. The results showed that there were differences in flush color on fine flavor cocoa and that of bulk cocoa. The flush of the fine flavor cocoa had a tendency towards yellow and that of bulk cocoa had a tendency toward red with different levels of variation among genotypes. The analysis results of chlorophyll content in flush showed that chlorophyll content of fine flavor cocoa was higher than bulk cocoa with a range of 2376-3692 µmol/L for fine flavor cocoa and 1567-2628 µmol/L for bulk cocoa. On the contrary, anthocyanin content in fine flavor cocoa was lower than bulk cocoa with a range of 3.82-5.72 µmol/L for fine flavor cocoa and 6.01-11.88 µmol/L for bulk cocoa. The analysis results of orthogonal contrasts showed that chlorophyll content value was more stable than anthocyanin. There was negative relationship between anthocyanin and chlorophyll in flush with the regression Y = -221,1X + 3935 with a value of correlation r = -0.50. The anthocyanin and chlorophyll content in flush had a potential to be used as selection markers for fine flavor cocoa hybrid

Persian lime is economically important for Mexico. However, the disease known as Huanglongbing (HLB) causes chlorosis symptoms in the foliage that affect the growth and decreases the yield of the trees. The expression of chlorosis symptoms is associated with starch accumulation and inhibition of antioxidant activity. The objective of the present work was to determine the effect of the application of three resistance elicitors on the expression of three antioxidant genes and on starch and chlorophyll content in Persian lime trees with HLB. Salicylic acid (SA), jasmonic acid (JA) or gamma-aminobutyric acid (GABA) were applied every eight days for nine weeks using a completely randomized design and a one-way ANOVA was performed for the analysis. Expression of APX, CAT and SOD genes was quantified at week nine at four different times. Starch and total chlorophyll content was estimated every three weeks by spectrophotometric methods. The application of the elicitors significantly increased the expression of the three genes, with SA and GABA generating the greatest increase at different times of application. No difference was found in starch and total chlorophyll content at most of the times evaluated. The use of resistance elicitors is promising in the management of HLB in plots already infected, seeking to extend the productive life of the orchards and thus counteract the economic losses caused by HLB.

ABSTRACT: Improper management of weeds is one of the causes of low bean yield, as it is very susceptible to interference due to their slow initial growth. This study aimed to evaluate the influence of dayflower on grain yield and nutrient accumulation of bean cultivars. The experiment was carried out in a screened house, in 5 L pots, in a 2 x 4 factorial scheme. Factor 1 corresponded to the presence or absence of weeds, and factor 2 bean cultivars: BRS Pontal, BRS Agreste, BRS Ametista and BRS Estilo. The experiment was arranged in a completely randomized design with five replications. The coexistence of bean and weed was maintained throughout the crop cycle. Chlorophyll content, number of pods per plant, number of grains per plant, nutrients contents (N - nitrogen, P - phosphorus, K - potassium, Ca - calcium, Mg - magnesium, Mn - manganese, Fe - iron and Zn - zinc) in grains were evaluated. Competition with weeds negatively influenced chlorophyll content, number of pods, yield and N content in grains. The interaction was significant to P, Mg and Fe contents in grains, demonstrating that competition with weeds may impair allocation of these nutrients, resulting in grains of inferior nutritional quality. The cultivar BRS Agreste was more efficient to accumulate P and Mg in grains in competition with dayflower.

Plant leaves are the primary source of natural colorants for food, mainly due to their chlorophyll content. However, the plant types and the degree of leaf maturity determine the quality and quantity of the chlorophyll. This study aimed to determine the best maturity level of pandan (Pandanus amaryllifolius Roxb.) leaves that serves as potential source of chlorophyll for natural food colorants. Eighty three pandan plants obtained from six different farming locations in Bantul Regency, Yogyakarta, Indonesia were used as samples. The leaves were grouped into four levels of maturity using descriptive statistics based on their morphology, anatomy, color, and chlorophyll contents. The results showed that the average number of leaves ranged from 20-24 leaves per plant (at 95% confidence interval), and 96.4% of the plant had a maximum of 24 leaves. The leaf maturity was grouped into (1) young, (2) medium, (3) mature, and (4) over mature, corresponding to leaf number 1-6, 7-12, 13-18, and 19-24, respectively. The higher the leaf maturity, the higher the chlorophyll content. However, the over mature leaves were only slightly different from the mature ones. In addition, pandan leaves have specific flavor and contain carotenoid, phenolic, and flavonoid substances. Anatomically, the mesophyll’s size was greatest in the mature leaves, while the size of chloroplast was not significantly different from medium to over mature leaves. Based on the chlorophyll content and mesophyll size, it was concluded that mature pandan leaves were the best source of chlorophyll, containing chlorophyll of 623.08 mg/100 g dry weight (DW).
