And Storage

‘Maha Chanok’ 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-1) 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-1 1-MCP for 24 h had the maximal fruit firmness. For chlorophyll content, the results showed that fruit-treated with 1500 nl l-1 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-1 1-MCP for 12 h.

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.

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.
