Production of vertebrate-dispersed fruits is the most common strategy of tropical woody plants to disperse their seeds. Few studies have documented community-wide variation of fruit morphology and chemistry of vertebrate-dispersed fruits in species-rich tropical communities. We examined the functional diversity of fruit morphological and chemical traits of 186 species representing 57 plant families in an undisturbed lowland plant community in the Atlantic rain forest of SE, Brazil. We were particularly interested in associating morphological and chemical fruit traits to their main seed dispersers, either birds, mammals or 'mixed' (i.e. fruits eaten by birds and mammals). The morphological and chemical traits of fruits at the study site generally resemble the patterns observed in fruits worldwide. Bird fruits tend to be smaller than mammal fruits, being colored black or red, whereas mammal fruits are often yellow or green. Mammal fruits are more variable than bird fruits in relation to morphological traits, while the reverse is true for chemical traits. Mixed fruits resemble bird fruits in the patterns of variation of morphological and chemical traits, suggesting that they are primarily bird-dispersed fruits that are also exploited by mammals. Mixed fruits are common in tropical forests, and represent an excellent opportunity to contrast the effectiveness of different functional groups of frugivores dispersing the same plant species.

ABSTRACT The market requirement regarding fruit type varies from region to region and it is necessary to produce cultivars with different patterns of fruit morphology. Therefore, the aim of this study was to select lines with resistance to tomato leafminer and different fruit shapes in order to meet the different market segments. Seventy-six lines and pre-selected populations were used for pest resistance together with four other susceptible controls (TOM-584, TOM-684, NC-123S, and Santa Clara) and two wild accessions (Solanum pennellii ‘LA 716’ and S. habrochaites var. glabratum ‘PI-127826’) considered resistant. The experiment consisted of tests of resistance to the tomato leafminer Tuta absoluta. The selection of lines was efficient, being obtained 33 lines or populations resistant to the tomato leafminer that comprise the market segments of the types of multilocular fruit, Santa Cruz, Saladette or Italian, as well as intermediate standards of fruits.

AbstractThis study evaluates the agronomic and morphological traits, chemical composition and traits related to consumer perception of local tomato landraces mostly collected in the suburban area of Madrid. Results showed remarkable variability at all the studied levels in this small area – intra- and inter-accession variability, and in morphological, agronomical and quality traits – and was often dependent on the environmental conditions where the crop was grown. However, few morphotypes could be defined. Some morphological traits of the studied samples seemed to be associated. For instance, ribbed fruits ripened with green shoulder and dark flesh accumulated more soluble solids. Consumer appreciation and fruit morphology, i.e. traits related to fruit size and shape, seemed to be the main determinants of tomato-type definition, although nutrient content also played an important role. Consumers positively received heirloom tomatoes, especially when they were cultivated in the open-field near their area of selection where they express their full potential in the nutrient synthesis and sensory properties. Although total soluble solids content seems to be the main trait related to appreciation, some morphological traits could be determinant in consumers’ choice. Furthermore, some consumers were more interested in different tomato typologies and nutritional characters like acidity.

Shape And Size

Tomato (Solanum lycopersicum L.) is the second most-consumed vegetable in the world. The market value and culinary purpose of tomato are often determined by fruit size and shape, which makes the genetic improvement of these traits a priority for tomato breeders. The main objective of the study was to detect quantitative trait loci (QTL) associated with the tomato fruit shape and size. The use of elite breeding materials in the genetic mapping studies will facilitate the detection of genetic loci of direct relevance to breeders. We performed QTL analysis in an intra-specific population of tomato developed from a cross between two elite breeding lines NC 30P × NC-22L-1(2008) consisting of 110 recombinant inbred lines (RIL). The precision software Tomato Analyzer (TA) was used to measure fruit morphology attributes associated with fruit shape and size traits. The RIL population was genotyped with the SolCAP 7720 SNP array. We identified novel QTL controlling elongated fruit shape on chromosome 10, explaining up to 24% of the phenotypic variance. This information will be useful in improving tomato fruit morphology traits.

Vegetative community structures and phenotypic variations within Calligonum comosum L`Her individuals grown in two different locations in Al-Nefud desert in Saudi Arabia; Nefud Al-Shakika and Al-Dahnaa, have been studied. Eleven species have been recorded in both areas; five of them were present in both locations. Ephedra elata and Convolvulus lanatus were recorded in Nefud Al-Shakika only. While Heliotropium bacciferum, Cleome arabica, Dodonaea viscosa and Erodium gleurocophyllum were found in Al-Dahnaa only. The importance values of the species recorded have been calculated and cluster analyses of the studied quadrates have been made using TWINSPAN method. Vegetative morphological characters showed great variations within C. comosum collected from the two locations. Floral morphological characters are more stable, except the fruit colour and hair which was different in the C. comosum plants grown in the two locations. Epidermal stem secretions as well as mineral contents varied in response to change in locations. ANOVA test have been carried out to evaluate the differences between the two areas. The variations in these characters are discussed according to the difference in climates, soil characters and water availability.

Basal Position

Caiophora is a taxonomically difficult, nearly exclusively Andean genus of the largely South American family Loasaceae subfam. Loasoideae. Elevational distribution and flower morphology argue for a relatively basal position of loasoid Caiophora in the genus. Caiophora has not been revised since 1900, and details of their morphology, distribution and species delimitation are incompletely understood. The Caiophora pterosperma-group clearly belongs to Caiophora based on habit, fruit morphology, karyology and molecular data, but is florally similar to members of the closely allied genera Loasa and Scyphanthus. The Peruvian members of the Caiophora pterosperma-group are here revised. Three species are recognized: C. pterosperma, endemic to the departments of Junín and Pasco (including C. smithii, C. serropetala and C. pavonii), C. stenocarpa from the departments Cuzco and Huancavelica, and the new species Caiophora dederichiorum, endemic to the department of Ancash. All three species occur at low elevations for the genus (down to 2200 m a.s.l.) and in seasonally dry habitats, unlike most representatives of the genus (usually found in mesic habitats at higher elevations). A key to the Peruvian members of the group, diagnoses, drawings and photographs are provided for all species recognized.
