background and objectives:  hawthorn is a forest fruit tree which is grown in the temperate regions around the world. this plant is known as the most traditional herbal remedy for heart failure and cardiovascular disease in worldwide. this study has been conducted to investigate the genetic variability and classify hawthorn genotypes based on quantitative and qualitative characteristics of leaf...

to determine the relationship between yield and components of it and identify the effective traits on yield, 97 tomato landraces from west azarbaijan in iran (83 landraces) and iğdır in turkey (14 landraces) along with three commercial cultivars were studied using an alpha lattice design with two replications. the experiment was carried out at the agriculture and natural resources research cent...

A study on evaluation of sapota genotypes collected from different parts of India was carried out at the Department of Fruit Crops, Horticultural College and Research Institute, Periyakulam during the year 2008-2009. Observation on quantitative traits viz., tree height (m), canopy spread (m), number of fruits/tree, mean fruit weight (g) and yield of fruits/tree (kg) were recorded. In addition, ...

The long-term objective of tomato breeders is to identify metabolites that contribute to defining the target flavour and to design strategies to enhance it. This paper reports the results of network analysis, based on metabolic phenotypic and sensory data, to highlight important relationships among such traits. This tool allowed a reduction in data set complexity, building a network consisting ...

cross pollination in some of apples cultivar exists; also iran is near the origin of apple trees so, large genetic diversity can be seen between iranian cultivar. also very famous apple cultivar is known in iran for special flavor and taste. the name of this cultivar is golab. this research was studied in the years 2010 and 2011 in khorasan razavi province on golab apple ecotypes to evaluate ch...

identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. in order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in minoodasht region in golestan province (north of iran) were evaluated. traits such as nut shape, kernel color, ease of removal of kernel halves, ke...

In order to study the effect of nitrogen rate and plant density on morphological traits and essential oil and fruit yield of coriander, a split-plot experiment was carried out in research field of Islamic Azad University, Birjand Branch, Birjand, Iran in 2010 based on a randomized complete block design with three replications. The main plots were nitrogen rates at four levels (0, 40, 80 and 120...

In seed-dispersal mutualisms, the number of fruit a plant displays is a key trait, as it acts as a signal for seed dispersers that entails fruit removal and exportation of reproductive units (fruit crop size hypothesis). Although this hypothesis has gained general acceptance, forces driving the shape and strength of natural selection exerted by birds on fruit crop size remains an unresolved mat...

Seed dispersers play a key role in the ecology and evolution of fleshyfruited plants; especially in tropical forests where from 70% to 90% of all woody species are dispersed by vertebrates (Fleming et al., 1987; Jordano, 2000). Local plant communities with a range of fruit types are assembled under a variety of selection pressures and historical effects. Analyses of community-level variation in...
