As the first organ in plants to sense water-deficit in the soil, roots have important roles for improving crop adaption to water limited environments. Stem water soluble carbohydrates (WSC) are a major carbon source for grain filling under drought conditions. The contributions of root WSC during grain filling under drought has not been revealed. Wheat parental lines of Westonia, Kauz and their ...

irrigated barley is grown on about 50,000 hectares in the warm agro-climate zone in the south of iran. the average grain yield of barley in these areas is 2,000 kg/ha. wide adaptability and high grain yield stability are important assets for barley varieties to be grown by farmers. zahak barley cultivar was initially selected from international barley germplasm received from cymmit and based on...

The experiment was conducted to investigate potential causes of grain sterility in widely cultivated rice variety in Malaysia, MR219 and its two mutant lines (RM311 and RM109) by examining the source-sink relations. RM311 produced increased dry matter yield both at heading and maturity and also showed higher grain yield with greater proportion of grain sterility than the other two genotypes (RM...

Increasing demands for productivity together with environmental concerns about fertilizer use dictate that the future sustainability of agricultural systems will depend on improving fertilizer use efficiency. Characterization of the biological processes responsible for efficient fertilizer use will provide tools for crop improvement under reduced inputs. Transcriptomic and metabolomic approache...

a total of twenty local and foreign maize (zea mays l.) hybrids in five different maturity group were studied in mashhad for two years (2007-2008). temperature variations were created by two planting dates (5 may and 20 may). results indicated that both indices, gdd and chu, estimated heat units of different maturity hybrids and based on, created similar groups of hybrids. both indices showed s...

this study was conducted to evaluate 13 promising triticale lines and cultivars based on yield traits, metabolizable energy and anti-nutritional compounds. the experiment was carried out using a rcb design with three replications at the seed and plant improvement institute, karaj and gonbad, during 2008-2009 cropping season. these genotypes were studied in the next year, at the animal science r...

We provide the raw data for protein and peptide identification and quantization of superior and inferior spikelets in hybrid rice during grain filling. The mass spectrometry proteomics data have been deposited to the Proteome Xchange Consortium via the PRIDE partner repository with the dataset identifier PXD001046. Our data presented here is also related to the article "Comparative proteomics a...

sunn pest (eurygaster integriceps put.) is one of the major pests of wheat in iran. identification of resistantcultivars is an effective integrated pest management (ipm) strategy. to identify the genetic response of wheat and triticale to sunn pest, and determine the relationship between resistance and morpho physiological traits, eight bread wheat breeding lines/cultivars, four durum wheat lin...
