Phenotipic diversity and biometry of fruit and seeds of a natural population of Cenostigma macrophyllum Tul. The aim of this study was to characterize and estimate the phenotipic diversity of Cenostigma macrophyllum in a natural population in the state of Piauí (PI), Brazil, from the physical characteristics of the fruit and seeds. The data were collected in the municipality of Floriano, PI. The following variables were evaluated in biometry: fruit length (mm), fruit width (mm), fruit weight (g), number of seeds per sample fruit, seed length (mm), seed width (mm), and seed thickness (mm). The biometric data were analyzed by descriptive statistics, and deviations from normality of the data were confirmed by the Lilliefors test for use of the Spearman non-parametric correlation. The phenotipic divergence observed among the individuals was based on cluster analyses (Tocher and UPGMA) and principal components. According to principal components and the dendrogram, individuals 3 and 11 have the greatest dissimilarity. The variables related to the fruit (length, width, and weight) had significant positive correlation, and these variables were the ones that most contributed to intraspecific variation. The results obtained were relevant because they will assist studies related to pre-breeding and conservation of the species.

O objetivo deste trabalho foi avaliar a biometria e morfologia de S. brasiliensis, visando identificar características que auxiliem no uso e propagação dessa espécie da Caatinga em programa de restauração ambiental. Os dados biométricos foram obtidos a partir de 1000 frutos e 1000 sementes. Foram medidos o comprimento, largura, espessura e massa de frutos e sementes. Os dados foram ajustados utilizando a estatística descritiva e teste de Shapiro-Wilk. Para a descrição morfológica dos frutos, foram relatadas observações sobre os aspectos externos e internos do pericarpo, consistência da casca, coloração, brilho, forma e deiscência. Já as descrições morfológicas externa das sementes foram feitas observações sobre consistência, coloração, textura, forma e hilo. A caracterização biométrica de frutos e sementes de S. brasiliensis, possibilitou verificar a variação existente entre as classes biométricas através de histograma de frequência. Os frutos apresentam morfologia completa, em forma de sâmara, indeiscente e monospérmico. As sementes foram caracterizadas em oblongas e reniformes, envolvidas pelo endocarpo, resultando no pirênio, sendo esta a camada que dificulta o processo de embebição de água, a qual antecede a germinação, no entanto, esta camada é capaz de promover maior longevidade as sementes.Palavras-chave: análises biométricas, características morfológicas, sementes florestais, Caatinga. BIOMETRIC AND MORPHOLOGICAL ASPECTS OF THE FRUITS AND SEEDS OF SCHINOPSIS BRASILIENSIS ABSTRACT:The objective of this work was to evaluate the biometry and morphology of S. brasiliensis, aiming to identify traits that help in the use and propagation of this Caatinga species in an environmental restoration program. Biometric data were obtained from 1000 fruits and 1000 seeds. The length, width, thickness and mass of fruits and seeds were measured. Data were adjusted using descriptive statistics and Shapiro-Wilk test. For the fruits morphological description, observations on the external and internal traits of the pericarp, peel consistency, coloration, brightness, shape and dehiscence were reported. Already the external morphological descriptions of the seeds were made on consistency, color, texture, shape and thread. The biometric characterization of fruits and seeds of S. brasiliensis made it possible to verify the variation between the biometric classes through frequency histogram. The fruits presented complete morphology, in the form of a samara, indiscriminate and monospermic. The seeds were characterized in oblong and reniform, surrounded by the endocarp, resulting in the pyrenium, which is the layer that hinders the process of water imbibition, which precedes the germination, however this layer is able to promote greater longevity of the seeds.Keywords: biometric analyzes, morphological traits, forest seeds, Caatinga. DOI:

Species arboreal, native of the Atlantic Forest biome, Poincianella pluviosa var. peltophoroides (Benth.) L.P. Queirozis widely used in urban landscaping due to the beauty of its flowering and indicated for the recovery of degradedareas as an initial or pioneer secondary species. The objective of the study was to characterize the fruits and seedsbiometrically, thus helping in its conservation and improvement. The work was conducted at the Federal Universityof Campina Grande, campus of Patos-PB, and the fruits were collected manually in matrices located on campus, usingas a selection criterion those who were mature. To obtain the biometric data, the fruits were selected and separated100 fruits and 100 seeds at random. To measure the biometric variables (length, width and thickness) of the fruitsand seeds, a digital caliper with a precision of 0.1 mm was used and then the amplitude of the classes of each analyzedvariable was calculated. The results showed that the fruits presented variation in the length of 4.51 to 10.53 cm,however, the predominance of fruit frequency was in the class of 6.03-6.77 cm. The seed length varied from 0.918 to1.208 cm, with a higher incidence in the class of 1.064-1.112 cm, where it concentrated about 45% of the seeds. It isconcluded that the fruits Poincianella pluviosa var. peltophoroides presented greater uniformity in the variable lengthand their seeds presented greater uniformity in the biometric variables in which they were evaluated, being this afavorable criterion for its propagation.

Mature fruit of 330 accessions of Capsicum chinense Jacq. from the USDA/ARS Capsicum germplasm collection were characterized for fruit length, width, weight, and color. Mean fruit length was determined to be 47 mm with a range from 7.9 mm to 113.7 mm. Mean fruit width was 21.17 mm with a range of 6.18 mm to 40.0 mm. Mean fruit weight was 6.31 g with a range of 0.18 g to 22.7 g. Distributions of all characteristics were positively skewed. Distributions of fruit length, fruit weight, and fruit length/width failed the Kolmogorov-Smirnov test for normality. The distribution for fruit width was normal. Ninety-two percent of the accessions examined were elongate. Mature fruit colors included red, orange, yellow, brown (chocolate), and cream. The germplasm collection contained primarily pendent larger-fruited cultivated forms of the species, but also contained upright small-fruited primitive and semipendent transitional forms. These data define the variability for mature fruit characteristics within this germplasm collection and provide a baseline against which future introductions/acquisitions can be compared. Additional sampling of the gene pool might be expected to substantially enhance the genetic variability within the primitive forms of this species.

Abstract Rice Grain dimension and weight are two critical factors for marketing and increasing yield capacity. Seed shape is measured by its length, width, thickness, and ratio of length-width. In this study, an experiment was conducted in a controlled condition from fall 2017 to 2020 to identify QTL and candidate genes associated with seed dimension and weight using a bi-parental population resulting from two University of Arkansas developed genotypes: a restorer line 367R and an advanced breeding line RU1501139, in Stuttgart, Arkansas. Five seed dimension traits, including seed length, seed width, seed thickness, seed length-width ratio, and 100-seeds weight, were obtained for QTL detection. The study detected a total of 17 QTL. Four QTL associated with seed length were identified, in which two were positioned on chr. 3, one on chr. 7, and one on chr. 11. Two QTL related to seed length-width ratio were detected on chr. 3 and 7. Whereas a total of three QTL were identified for seed thickness, one each on chr. 5, 6, and 8. Eight QTL associated with seed weight were found, of which four QTL were detected on chr. 12, two each on chr. 1 and 10, and one on chr. 3. Of 17 QTL, four QTL originated from RU1501139, while the origin of the other 13 QTL was 367R. Since multiple genes could control the yield and seed physical characteristics, the detected QTL can play a role in introducing superior parental lines for developing conventional and hybrid rice production.

The micromorphological characteristics of the seeds of 11 species of Pleione have been studied, both qualitatively and quantitatively, to establish whether they are useful for systematic studies of the genus. The quantitative characteristics include seed length (0.237–0.626 μm), seed width (0.053–0.133 μm), seed length/width ratio (2.631–7.279), seed ridge thickness (1.4 E-3–4 E-3μm) and seed volume (1.88 E-4–3.06 E-3 μm3). The cluster analysis result agrees well with the results of previous systematic studies. The cluster analysis shows that: P. coronaria, P. forrestii and P. yunnanensis form a group, while the remaining eight species form a second group, with three subgroups, namely: P. limprichtii, P. pleionoides, P. formosana as group I; P. hookeriana and P. bulbocodioides as group II; and P. praecox, P. scopulorum and P. maculata for group III. All the Pleione species of Sect. Pleione and Sect. Humiles show the fusion of adjacent seed coat cells into a network. The shape of the seeds of P. praecox and P. maculata are very similar--being oval, and the mesh walls of their adjacent seed coat cells are not fused. Within these sections no clear pattern can be seen between the species, but the addition of further species might clarify the differences between Sect. Pleione and Sect. Humiles.

Mature fruit of 295 accessions of Capsicum baccatum from the USDA/ARS Capsicum germplasm collection were characterized for fruit length, width, weight, and color. Mean fruit weight was determined to be 5.91 g with a range of 0.15 to 22.8 g. Mean fruit length was 6.01 cm with a range of 0.8 to 16.0 cm. Mean fruit width was 1.86 cm and a range of 0.5 to 4.75 cm. Distributions of all characteristics were positively skewed and failed the Kolmogorov-Smirnov test for normality. The distribution of fruit weight values was the most highly skewed, possibly reflecting a more intense human selection pressure for this characteristic. Distributions of fruit width, length, weight, and length:width were leptokurtic (long-tailed). Ninety-three percent of accessions were elongate. Mature fruit colors included red (73.6%), orange (19.7%), yellow (3%), green (0.3%), and mixed (3%). These data suggest that variability for mature fruit characteristics within this germplasm collection is considerable and that variability for fruit length, width, weight, and color is sufficient to provide the basis for the improvement of the aji crop.

Fruit Quality Traits

Abstract Apricot (Prunus armeniaca L.) is a world-wide highly appreciated fruit, with its attractive colour, soft texture and typical flavour. In the current investigation, 68 apricot accessions collected from Jammu and Kashmir, India were analysed to determine the measure of variation using 12 qualitative and 16 quantitative traits with an aim to identify superior apricot accessions with excellent fruit quality traits. High phenotypic variability was observed among the studied apricot accessions with significant differences among most of the qualitative and quantitative traits. Fruit-related characteristics including fruit weight, fruit length, fruit ratio, fruit firmness, fruit shape, fruit suture, stone weight, kernel weight and stone shape were the most diverse with a high coefficient of variation (>30%). One way analysis of variance showed significant differences (P < 0.0001) among all the quantitative traits. Significant positive and negative correlations were observed between all the agronomically important fruit quality traits. The principal component analysis (PCA) revealed that 75.34% of the variability was defined by the first eight components. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram, based on all traits measured grouped the accessions into two main clusters with several sub-clusters. Both UPGMA dendrogram and PCA scatter plot formed a cluster of 14 accessions, having the highest values regarding most important fruit quality traits such as fruit weight, fruit length and width, fruit ratio, stone weight and kernel weight can be treated as potentially superior accessions. These accessions can be used directly for cultivation and in future apricot breeding programmes. The present findings are promising for genetic resource management, cultivar improvement and commercial applications of apricot in Jammu and Kashmir, India.

Some physico-chemical properties of ten pomegranate accessions collected from different districts in the Kurdistan region of Iraq were investigated in this paper. Considerable correlations between the characteristics studied were found and valuable pomological traits were observed. Cluster analysis showed the homonyms between some pomegranate accessions. Principle component analysis reported that the component describing the greatest variability also positively correlated with fruit weight, total aril weight, total peel weight, volume of juice, total soluble solids (TSS), fruit length, fruit diameter, pH, aril length, and 100-seed fresh weight, but negatively correlated with titratable acidity (TA). Fruit weight was firmly correlated with total aril weight, total peel weight, volume of juice, TSS, aril length, 100-seed fresh weight, fruit length and fruit diameter. The volume of juice was correlated with TSS, aril length, 100-seed fresh weight, fruit length, fruit diameter and it was observed that with an increase in the fruit size, the volume of juice increased as well. The correlation between total phenolic compounds and antioxidant capacity was not observed. The associations found among physical and chemical traits suggest that consumers should use large fruits with large arils so that they have more juice. Thus, ?Choman?, ?Raniyeh? and ?Halabja? were juicier than other accessions.

The use of information and communication technologies (ICT) by students reflects the appropriateness of the ICT integration process. However, the typology of ICT use by students has not been established empirically based on their use at home and at the school. Thus, the purpose of the article is to determine the structure of ICT use by students, together with the influence of personal and contextual factors. A correlational design has been used, with the sample being the sixth-grade students in Latin America who answered the questionnaire on ICT use in the Third Regional Comparative and Explanatory Study (TERCE). The data analysis performed is descriptive statistics, Multivariate Analysis of Variance (MANOVA) and Categorical Principal Components analysis (CATPCA). The results obtained through the descriptive statistics show how the students make a greater use of technological resources in the area of free time than in the academic area. It has been found, by means of a categorical principal components analysis (CATPCA), that student use is structured in three planes: personal, non-school academic and school academic. In addition, the results obtained from the MANOVA indicate that the personal and contextual factors influence the use of ICT, essentially the availability of technological devices and the Internet connection. In the light of the results, it is recommended to implement programs that favour non-school academic use of ICT by students.
