Fruits of Capsicum chinense, a native species of Amazon Basin, express high levels of bioactive components such as vitamin C and carotenoids; some of them with pronounced pro-vitamin A activity such as β-carotene, which confers high economic potential to this species. The characterization of C. chinense germplasm helps in its management and conservation. Therefore, this practice is considered crucial for the identification of genotypes with superior characteristics, especially in relation to agronomic aspects and chemical-nutritional characteristics of fruits. This study aimed to characterize 55 C. chinense accessions collected from the Brazilian Amazon in terms of their agronomic and chemical-nutritional descriptors aiming to identify superior genotypes for these traits. The characterization was performed in a completely randomized design with 5 replications in non-heated environment. There was significant difference for all descriptors, confirming the variability among accessions. High heritability estimates for descriptors, such as fruit yield (95.1%) and vitamin C content of fruit (92.4%), was found to be associated with high CVg/CVe ratios of these traits, indicating a favorable condition for the selection of superior genotypes for these characteristics. A considerable part of the accessions expressed averages higher than the checks, notably for the fruit yield and the content of vitamin C. The cluster analysis resulted in the formation of 11 groups, corroborating the high variability of accessions for the agronomic and chemical-nutritional aspects of fruits. The evaluated C. chinense germplasm thus expressed high fruit yield and vitamin C content in the fruits, which makes it a promising source for the selection of superior genotypes.

Capsicum Species

Fruits of Capsicum species (peppers) accumulate high amounts of ascorbic acid or vitamin C. C. chinense occurs in the Midwest and Northeast regions and the Amazon Basin (where its greatest genetic diversity is found). The objective of the present work was to quantify the vitamin C content in peppers of 22 accessions of C. chinense 'Habanero' from the Breeding Program of Embrapa Vegetable Crops. Vitamin C was extracted from mature fruits with TCEP-HCl (tris 2-carboxyethyl-phosphine hydrocloride) and its content determined by high performance liquid chromatography (HPLC). Vitamin C content ranged from 54.1 to 129.8 mg/100 g. Accessions were divided into four heterogeneous groups of diversity. Vitamin C content of the first group varied between 116.2 and 129.8 mg/100 g; the second group ranged from 94.0 to 104.6 mg/100 g; the third group ranged from 76.7 to 87.5 mg/100 g; and the fourth group ranged from 54.1 to 66.6 mg/100 g. These results highlight the diversity of C. chinense collection in terms of vitamin C content.

The nutritional quality of the food has become a serious concern in existing agricultural system as the present world aims to enhance only the food production. A field experiment was carried out to study the effect of different fertilizers on growth, vitamin C and calcium content in yield of Capsicum chinense at Regional Agricultural Research and Development Center, Makandura consisting four treatments as without fertilizer (control/ T1), only compost (T2), compost + inorganic fertilizer (T3) and only inorganic fertilizer (T4) with a randomized complete block design (RCBD) replicating four times. Vitamin C content was measured by Indophenol dye redox titration method and calcium content was analyzed by atomic absorption spectrophotometer. Data was analyzed using analysis of variance. The highest growth was recorded in T3 and no significant differences between treatments in growth parameters at 50% flowering stage.The Vitamin C content was highest in treatment with only compost (T2) and the lowest in treatment compost + inorganic fertilizer (T3). The results indicated that yield from organically managed crops contain significantly higher amount of vitamin C (9.24±2.27 mg/100g, p= 0.0274). The highest calcium content was found in T1 (control) (1.1±0.05 %) and a significant difference (p= 0.0296) was observed between T1 (control) and T3 (calcium=0.75±0.12 %). Compost alone can be used to produce food with high amount of vitamin C. Use of inorganic fertilizer alone or integration of compost with inorganic fertilizer was less effective in producing high quality nutritious foods.

The aim of the study was to find effects of tomato grafting on another cultivar. The tomato cultivars used as scions were Yeni Talya, Swanson and Beril. Cultivars used as rootstocks were Beaufort and Arnold. Cleft grafting methods were applied. The following characteristics of grafted and nongrafted plants were recorded: fruit index, number of fruits/truss, fruit weight, fruit yield, dry matter, pH, concentration of soluble solids, titratable acidity, total sugar and lycopene and vitamin C. The results showed that fruit yield and fruit index, number of fruits/truss and fruit weights were improved by grafting. Fruit quality, measured in terms of dry matter, concentration of soluble solids, total sugar, and vitamin C content, was lower in the fruits of grafted plants than in nongrafted ones. No significant difference in lycopene and pH content was found. Titratable acid content was improved by grafting. A positive effect of grafting was recorded when Beaufort was used as rootstock. These results showed that grafting could be an advantageous alternative in tomato production.

Проведен фитохимический анализ цветков, плодов и листьев по содержанию биологически активных веществ на двух видах клена: инвазионном Acer negundo L. и аборигенном A. platanoides L. (Sapindaceae Juss). У 40 образцов, собранных в 5 популяциях Московского региона, найдены сумма флавоноидов, содержание аскорбиновой кислоты и суммы органических кислот по стандартным методикам Государственной фармакопеи РФ. В данном исследовании впервые обнаружено, что максимальное накопление флавоноидов (1,75-1,94 мг%) фиксируется в мужских цветках A. negundo. Содержание витамина С в цветках (до 53 мг%), плодах и листьях A. negundo на 25-30 % больше, чем в аналогичных органах у A. platanoides. По мере созревания плодов содержание флавоноидов, аскорбиновой кислоты и органических кислот (до 8 %) у инвазионного и аборигенного видов клена снижается почти в 1,5 раза. Листья мужских и женских особей A. negundo по насыщенности флавоноидами, витамином С и органическими кислотами не отличаются. Выявлено, что цветки A. negundo и A. platanoides, являются наиболее перспективным источником биологически активных веществ - флавоноидов, включая катехины, антоцианы, лейкоантоцианы и флавонолы, а также аскорбиновой кислоты. Сбор растительного сырья рекомендуется проводить в экологически чистых фитоценозах, поскольку известно о способности растений A. negundo аккумулировать из почвы и воздуха тяжелые металлы. A phytochemical analysis of flowers, fruits, and leaves revealing the biologically active substances in two types of maple: invasive Acer negundo L. and native A. platanoides L. (Sapindaceae Juss) was carried out. In 40 samples collected in 5 populations of the Moscow Region, a sum of flavonoids, the presence of ascorbic acid, and organic acids were found according to the standard methods of the State Pharmacopoeia of the Russian Federation. We discovered for the first time that the maximum accumulation of flavonoids (1.75-1.94 mg%) is in male flowers of A. negundo. The content of vitamin C in flowers (up to 53 mg%), fruits, and leaves of A. negundo is 25-30% higher than in similar organs in A. platanoides. As the fruit ripens, the content of flavonoids, vitamin C, and organic acids (up to 8%) in invasive and native species of maple decreases by almost 1.5 times. The leaves of male and female trees of A. negundo do not differ in saturation with flavonoids, vitamin C, and organic acids. Flowers of A. negundo and A. platanoides are the most promising source of biologically active substances - flavonoids, including catechins, anthocyanins, leukoanthocyanins, and flavonols, as well as ascorbic acid. The collection of plant substances is recommended in ecologically clean phytocenoses since A. negundo can accumulate heavy metals from soil and air.

ABSTRACT The study on the native species of fast growth and nodulation capacity, Ormosia discolor, intends to conserve genetic resources and make available seed lots of high vigor for seed orchards. This work evaluates the physical and physiological characteristics of seeds from 20 O. discolor trees as a subsidy for selecting superior mother trees. Twenty matrices selected from a population in the state of Amazonas were inventoried. Physical tests were performed on the seeds collected, including water content, biometrics, the weight of one thousand seeds, and coat permeability test. For vigor estimates and classification regarding seed storage, the seeds were frozen for five months. The germination test was carried out at a constant temperature of 30 °C. It was used a completely randomized design consisting of 20 mother trees, 4 replicates, and 25 seeds per plot. The germination characteristics evaluated were germination percentage, speed index, mean germination time, and synchronization index. Cut seeds are more efficient for determining water content. All biometric variables are representative for the selection of vigorous lots, with emphasis on geometric diameter, surface area, and sphericity of seeds. Species seeds were classified as orthodox and as having physical dormancy. The protrusion of the primary root is the best morphological characteristic for evaluating germination in the laboratory. The mother trees 7, 16, and 10 showed superior characteristics for dendrometric and technological data, being indicated for marking, phenological monitoring, and planting.

Four recently developed adolescent language tests, the Fullerton Test for Adolescents (FLTA), the Test of Adolescent Language (TOAL), the Clinical Evaluation of Language Functions (CELF), and the Screening Test of Adolescent Language (STAL), were compared to determine: (a) whether they measured the same language skills (content) in the same way (procedures); and (b) whether students performed similarly on each of the tests. First, respective manuals were reviewed to compare selection of subtest content areas and subtest procedures. Then, each of the tests was administered according to standardized procedures to 30 unselected sixth-grade students. Despite apparent differences in test content and procedures, there was no significant difference in students' performance on three of the four tests, and correlations among test performance were moderate to high. A comparison of the pass/fail rates for overall performance on the tests, however, revealed a significant discrepancy between the proportions of students identified in need of further evaluation on the STAL (20%) and the proportion diagnosed as language impaired on the three diagnostic tests (60-73%). Clinical implications are discussed.
