nitrogen is one of the most important and essential lelments for plant growth and development and it has an important role on quantitative and qualitative yield production in agriculture. this study was carried out to evaluate the effects of foliar application of nitrogen on qualitative traits of tomato fruits using a completely randomized design with five treatments and four replications under...

in order to evaluate genetic diversity among squash landraces from northwest iran by morphological and physiological traits, 18 squash landraces belong to pumpkin, ornamental and confectionary groups were planted in completely randomized block design with three replications in agricultural research center of urmia in 2013. morphological characteristics related of fruit, seed, leave and flower a...

identifying and selecting superior genotypes in native germplasm is one method for breeding fruit trees. five different ecotypes of jujube (ziziphus jujuba mill.) were collected from different regions of isfahan province, iran, for evaluation of their morphological and pomological traits during 2011-13. results showed that quantitative traits were more significant within ecotypes. ‘‘najafabad’ ...

a study of the combining ability and gene effects, that can obtained through diallel cross analysis provides considerable information to breeders for a design of breeding programs. inheritance and genetic control of yield and its components were studied in a full diallel cross for seven iranian cantaloupe cultivars namely: rish-baba, shah-abadi, samsouri, dastjerdi, magasi-neyshabour, till-toro...

Epidemiological studies suggest that consumption of fruit rich in phenolic compounds is associated with health-protective effects due to their antioxidant properties. For these reasons quality evaluation has become an important issue in fruit industry and in breeding programs. Phytochemical traits such as total phenolics, flavonoids, anthocyanins, L-ascorbic acid, sugar content and relative ant...

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...

Network theory has provided a general way to understand mutualistic plant-animal interactions at the community level. However, the mechanisms responsible for interaction patterns remain controversial. In this study we use a combination of statistical models and probability matrices to evaluate the relative importance of species morphological and nutritional (phenotypic) traits and species abund...

Peach (Prunus persica L.) is a highly valuable crop species and is recognized by molecular researchers as a model fruit for the Rosaceae family. Using whole-genome sequencing data generated from 129 peach accessions, here we perform a comprehensive genome-wide association study for 12 key agronomic traits. We show that among the 10 qualitative traits investigated, nine exhibit consistent and mo...

traits such as soluble solids content, fruit acidity, ph, fruit lycopene concentration, fruit beta-caroteneconcentration, and fruit xanthophyll concentration are very important to the tomato industry. in this study,quantitative trait loci (qtl) analysis of these traits was performed using a recombinant inbred line (ril)population derived from a cross between a tomato (lycopersiconesculentum mil...

to determine the effects of different pollen types and suitable pollination time in medjhol date palm, an experiment was carried out with three pollen cultivars: ghaname, vardy and samesmave and two pollination times (1-3 days before or after spathe opening) during 2010-2011 in date palm and tropical fruit research institute in ahwaz. the results showed that the vardy pollen had the most signif...
