growth traits, yield and fruit quality in ‘synda’ tomato were compared with those in tomatoes grafted onto either ‘king kong’ rootstock or onto their own rootstocks, (trained as single or double stem), and at two fruit thinning levels, of: no thinning or thinned to five fruits per truss. the data related to crop growth rate (cgr), relative growth rate (rgr), net assimilation rate (nar), leaf ar...

Early growth traits in sheep are economically important. Breeding for these traits has been shown to be problematic using quantitative genetic methods, particularly in native sheep herds. Molecular genetics is useful for sheep breeding. The gene for insulin-like growth factor 1 (IGF1) is one of the important candidate genes known for ovine early growth traits. The aim of this study was to inves...

Understanding differences among peanut (Arachis hypogaea L.) cultivars in growth and phenology and the interactions with environment (G X E interactions) for these traits allows predictions for yield potential or performance in variable environments. Despite the importance of this information, very little quantitative data exists on the differences in aboveground growth, canopy architecture, an...

Quantitative trait locus (QTL) is a particular region of the genome containing one or more genes associated with economically important quantitative traits. This study was conducted to identify QTL regions for body weight and growth traits in purebred Korean native chicken (KNC). F1 samples (n = 595) were genotyped using 127 microsatellite markers and 8 single nucleotide polymorphisms that cove...

In the current paper we investigate whether gender aVects the encoding of leadership behavior. In three studies we found evidence that perceivers had diYculty encoding leadership behaviors into their underlying prototypical leadership traits when the behavior implied an agentic trait and the behavior was enacted by a female. Using a lexical decision making task, in Study 1 we demonstrated that ...

Given finite resources, intense investment in one life history trait is expected to reduce investment in others. Although telomere length appears to be strongly tied to age in many taxa, telomere maintenance requires energy. We therefore hypothesize that telomere maintenance may trade off against other life history characters. We used natural variation in laboratory populations of Atlantic silv...

peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

Interspecific relationships among species mean leaf traits, performance and species resource/climate distributions help provide the foundation for a predictive, functionally based plant ecology. Intraspecific responses of leaf traits and performance to resource gradients and how these vary among species may be equally important but have received less attention. Here, we examine relationships be...
