In 1996, we investigated the female reproductive success of the narrow endemic Erodium paularense in a population with a mixture of rock and lithosol microhabitats. The main purposes of this study were to determine the main factors that affected reproductive success and whether these factors were influenced by differences in the two contrasting microhabitats. In both microhabitats, fruit set wa...

in order to evaluation of seed production index in lambsquarters (chenopodium album), leaf appearance and yield of fennel (foeniculum vulgare) under inter-specific competition a factorial experiment was conducted in islamic azad university, tabriz branch, iran, during 2011-2012. treatments were weed densities of 0, 2, 4, 6 and 8 plants per meter row and its relative emergence times of simultane...

The seed industry in Southern Africa has been radically transformed by a policy of liberalisation and privatisation started under structural adjustment. Traditionally under the domain of parastatals, seed research, production and distribution has been criticised for failing to provide modern variety seed to smallholder farmers. However, the private companies which have stepped in to replace see...

during the fragmented phases of the tree-improvement delivery system are reviewed. The impacts of intentional and unintentional directional selection during phenotypic selection, seed production (with its associated reproductive-phenology asynchrony, fecundity differential and varying propensity to inbreeding), seed processing and storage, and seedling production are evaluated. In general, gene...

in tropical pulses such as mung bean use of zeolite due to keep of moisture is important. to study of effects of seed pelleting with zeolite and seed priming with iron chelate on protein and grain yield of mung bean cultivars in ahvaz conditions, an experiment was conducted as a factorial in randomized completely block design (rcbd) with three replication in experimental farm of the ramin unive...

1 The geographical variation of seed production, predation and abortion was analysed in Juniperus communis for 31 populations in seven distinct regions throughout the species' distribution range in Europe, including both the northern and southern boundaries. 2 The number of seeds per cone and the number of ®lled seeds per cone varied signi®cantly between geographical regions and among populatio...
