Chili peppers are rich in ascorbic acid and capsaicin. In this article is proposed an easy, fast, sensitive, and inexpensive method for determining the pungency and content of ascorbic acid in chili pepper extracts. The voltammetric (cyclic and differential pulse) behavior of capsaicin on a glassy carbon electrode has been evaluated at different pH values. A calibration curve has been obtained for the peak current, IP, of capsaicin as a function of the capsaicin concentration, C, in differential pulse voltammetry in phosphate buffer solution at pH 7.0: IP(µA) = 0.0147 (±5.346·10−3) + 0.0507 (±8.984·10−4) C(µM), with limit of detection, LOD = 0.198µM, limit of quantification, LOQ = 0.660µM, and dynamic linear range from 0.660 to 20.9 µM. A variant of the standard addition method has been used for simultaneous determination of the pungency and ascorbic acid content of extracts of Capsicum annuum cubana red. In this case, the calibration for ascorbic acid was I(µA) = 0.467 (±0.012) + 2.039·10−3 (±4.601·10−5) VAA(L)), with LOD = 17.56 µL, LOQ = 58.55 µL, and dynamic linear range from 58.6 to 500 µL, being VAA the volume of 10-mM ascorbic acid added to 50 mL of solution. The ascorbic acid content was compared to that of a sweet pepper. The method is cheap, simple, and fast (30 min vs c.a. 2 h compared to the spectrophotometric method), its sensitivity being comparable to other more expensive and/or more laborious methods.

Greenhouse Production

Capsicum annuum is one of the most important plant species in the world. México has the greatest diversity for this plant. However, its production is limited due to the scarcity of improved varieties for greenhouse production. Therefore, the development of high-yield varieties would be possible through the genetic recombination of native varieties (Creole populations) and superior cultivars. Therefore, the purpose of this research work was to assess and select outstanding F3 populations for greenhouse production. The work was carried out in a greenhouse at Saltillo, Coahuila Mexico in 2018, involving 8 parents, in which 3 varieties were used as female (pollen-receptor plants), 5 varieties as males (pollen-donor plants) and 9 F3 populations derived by selfing from 9 F2 populations. The parents and F3 populations composed 17 treatments that were established in a greenhouse under a randomized block design with three replications. The variables were total fruit yield, average fruit weight, total number of fruits per plant, ascorbic acid content, total capsicinoids, days to flowering, days to harvest, final plant height, and basal stem diameter. Significant differences were found in all variables of F3 populations. The highest RTF (total fruit weight) belonged to P1,4 and P1,6, with1647.0 and 1652.0 g/plant, respectively. In terms of CAA (ascorbic acid content), population P2,4, was significantly superior to the rest of the genotypes and exceeded the best parent by 19.8%. We concluded that populations P1,4, P1,6 and P2,4 may be uased to develop cultivars with high yield and high quality for greenhouse production

AbstractCalcium (Ca) deficiency in cabbage plants induces oxidative damage, hampering growth and decreasing quality, however, it is hypothesized that silicon (Si) added to the nutrient solution may alleviate crop losses. Therefore, this study aims at evaluating whether silicon supplied in the nutrient solution reduces, in fact, the calcium deficiency effects on cabbage plants. In a greenhouse, cabbage plants were grown using nutrient solutions with Ca sufficiency and Ca deficiency (5 mM) without and with added silicon (2.5 mM), arranged as a 2 × 2 factorial in randomized blocks, with five replications. At 91 days after transplanting, the plants were harvested for biological evaluations. In the treatment without added Si, Ca deficiency promoted oxidative stress, low antioxidant content, decreased dry matter, and lower quality leaf. On the other hand, added Si attenuated Ca deficiency in cabbage by decreasing cell extravasation while increasing both ascorbic acid content and fresh and dry matter, providing firmer leaves due to diminished leaf water loss after harvesting. We highlighted the agronomic importance of Si added to the nutrient solution, especially in crops at risk of Ca deficiency.

The ascorbic acid (vitamin C) content of fresh imported field tomatoes and Nova Scotia greenhouse and field tomatoes was determined on a bi-weekly basis during the period of availability of each type of tomato to the Nova Scotia consumer in 1984. The average ascorbic acid contents of imported and Nova Scotia field and greenhouse tomatoes were 13.3, 16.7 and 17.7 mg 100 g−1 fresh weight, respectively. A study of nine recommended or promising field tomatoes for the Atlantic region showed significant differences in ascorbic acid content among the cultivars. The cultivar Quick Pick had the highest ascorbic acid content of 22.5 ± 1.5 mg 100 g−1, the cultivar Campbell 18 had the lowest content, 12.0 ± 2.9 mg 100 g−1. In Dombito greenhouse tomatoes the stage of maturity and the effect of cluster location were tested against ascorbic acid content. The lowest ascorbic acid content of 9.1 ± 1.0 mg 100 g−1 was found with the small green tomatoes while others from mature green to overripe contained 14.0–16.7 mg 100 g−1. Tomatoes from different cluster locations showed no significant difference in ascorbic acid content.Key words: Vitamin C, L-ascorbic acid, tomatoes
