Increased interest toward traditional tomato varieties is fueled by the need to rescue desirable organoleptic traits and to improve the quality of fresh and processed tomatoes in the market. In addition, the phenotypic and genetic variation preserved in tomato landraces represents a means to understand the genetic basis of traits related to health and organoleptic aspects and improve them in mo...

The extreme sensitivity of the microsporogenesis process to moderately high or low temperatures is a major hindrance for tomato (Solanum lycopersicum) sexual reproduction and hence year-round cropping. Consequently, breeding for parthenocarpy, namely, fertilization-independent fruit set, is considered a valuable goal especially for maintaining sustainable agriculture in the face of global warmi...

To make sense of the world around us, our brain must remember the overlapping features of millions of objects. Crucially, it must also represent each object's unique feature-convergence. Some theories propose that an integration area (or "convergence zone") binds together separate features. We report an investigation of our knowledge of objects' features and identity, and the link between them....

‘smyrna’ type figs (zidi ‘zd’: dark fruit and thgagli ‘thg’; bidhi ‘bd’ and khedri ‘khd’: white fruit) originated from two areas of fig production in tunisia were subject to physico-chemical description and spectrophotometric analysis for their sugar (glucose, fructose and sucrose) and organic acid (citric and malic) contents. fruit weight ranged between 54 and 82 g, fruit width between 47 and ...

The locus sun on the short arm of tomato chromosome 7 controls morphology of the fruit. Alleles from wild relatives impart a round shape, while alleles from certain cultivated varieties impart an oval shape typical of roma-type tomatoes. We fine mapped the locus in two populations and investigated the genome organization of the region spanning and flanking sun. The first high-resolution genetic...

Non-destructive quality inspection of fruits provides quality products for domestic consumption as well as for export markets, increasing consumer/buyer confidence. It provides assurance of quality and subsequent value addition. A major thrust of current research is towards the development of quality inspection systems for improved sorting and automated quality control. Machine Vision inspectio...

    Different dates for apples fruit harvest (Malus domestica Borkh. Cv. Fuji) were studied to determine physiochemical changes during the storage. Fuji apples were harvested from 9 September till 23 October, at five different times and stored at 0±0.5 °C and 95% relative humidity for 120 days. To determine the best harvest date for maximum quality and storability, physical and chemical paramet...

Cross incompatibility of wild Manihot species with cassava (M. esculenta) can impede their utilization for improving this cultigen. We tested whether compatibility could be determined based on electrophoresis results. Manihot pilosa, M. glaziovii, M. reptans, and M. cearulescens were tested. These species were allowed to hybridize with cassava to determine whether hybridization coincides with t...

Begonia kingdon-wardii Tebbitt was rediscovered in 2014 from Myanmar after 67 years based on its last collection in 1937. Its previously unknown female flower and inaccurate morphology of leaf and ovary have been additionally described. This species belongs to Begonia sect. Sphenanthera (Hassk.) Warb. due to its dioecious habit, 3-locular ovary, berry fruits and thick placenta segments. Morphol...

Abstract In the present study, I propose a new species, Quararibea bovinii, an Atlantic Forest tree. The taxon occurs in southeastern Brazil, states of Espírito Santo, Rio de Janeiro, and São Paulo. It resembles Q. similis terms floral morphology fruit shape, but it is distinguished by indumenta leaves, leaf width, seed shape.
