Both ploidy and hybridity affect cell size and growth vigor in plants and animals, but the relative effects of genome dosage and hybridization on biomass, fitness, and gene expression changes have not been systematically examined. Here we performed the first comparative analysis of seed, cell, and flower sizes, starch and chlorophyll content, biomass, and gene expression changes in diploid, tri...

The relationships between various carbohydrate pools of the soybean (Glycine max [L.] Merrill) fruit and growth rate of seeds were evaluated. Plants during midpod-fill were subjected to various CO(2) concentrations or light intensities for 7 days to generate different rates of seed growth. Dry matter accumulation rates of seeds and pod wall, along with glucose, sucrose, and starch concentration...

safflower is a crop native to iran and could be improved in plant breeding programs by inter-specific crosses. this study was conducted to evaluate genotypes of safflower derived from interspecific hybridization for the relationships between some agronomic traits and yield components. the genotypes were planted according to a randomized complete block design with three replications at the resea...

Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...

Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass species in the Songnen Grassland of Northern China. The objective of this study was to investigate and evaluate possible quality indices of the seed...

The experiment was conducted to find out the efficacy of dodder vine extract as seed protectant against pulse beetle, Callosobruchus chinensis on gram seed in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period of February to May, 2009. The concentrations of dodder vine extract were 5, 2 and 1% respectively. Efficacies of these treatm...

in order to determination of optimum quantity of seed pelleting materials due to sugar beet monogerm seed size. this study was carried out in seed technology department during 1997-1998. monogerm cultiver 9597 seed lot (300kg) was firstly graded by 7 round sieves and then 7 rectangle sieves graded each bound. some factors such as germination , monogermity and proportionate seed pelleting materi...

The large-scale mining and high-throughput genotyping of novel gene-based allelic variants in natural mapping population are essential for association mapping to identify functionally relevant molecular tags governing useful agronomic traits in chickpea. The present study employs an alternative time-saving, non-laborious and economical pool-based EcoTILLING approach coupled with agarose gel det...

in order to understand the effect of plant density and different fertilizers on sesame (sesamum indicum l.) production, an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications. the experimental treatments were fertilizers in four levels (cow manure (30 t.ha-1), municipal compost (30 t.ha-1), chemical fertilizer (250 kg ammonium ...

to determine the association between genetic parameters and traits in chickpea (cicer arietinum l.) genotypes, a field experiment was conducted with 17 chickpea genotypes using a randomized complete block design with four replications at the ilam agricultural and natural resources research center in the 2004 growing season. genetic parameters including genetic, environmental and phenotypic vari...
