Population genetics models typically consider a fixed population size and a unique selection coefficient. However, population dynamics inherently generate noise in numbers of individuals and selection acts on various components of the individuals’ fitness. In plant species with seed banks, the size of both the aboveand below-ground compartments present noise depending on seed production and the...

Pre-dispersal seed predation (PDSP) is commonly observed in woody plants, and recognized as a driver of seed production variability that is critical for successful regeneration. Earlier studies on PDSP and its determinants were mostly species specific, with community-level PDSP rarely estimated; and the interactions between the temporal variability of seed production and PDSP remain elusive. In...

seed hardiness in annual medics plays an important role in soil seed bank reserve to ensure ley farming system sustainability. to study the level of seed hardiness in annual medic (medicago scuttelata var.rabinson) at different fertilizing treatments and growing conditions (irrigated and dry farming system), an experiment was conducted at two research stations (sararod, research institute and s...

PURPOSE To investigate the dosimetric characteristics of the new GMS BT-125-1 125 I radioactive seed, including dose rate constant, radial dose functions, and anisotropy functions. METHODS Dosimetric parameters of GMS BT-125-1 125 I seed including dose rate constant, radial dose functions, and anisotropy functions were calculated using the Monte Carlo code of MCNP5, and measured with thermolu...

Background: Chickpea is a cool season legume crop and grown in several countries worldwide as food source. Seed the main edible part of plant rich source protein, carbohydrates minerals especially for vegetarian population. The current study aimed to effect seed rate spacing on yield attributes chickpea. Methods: research was carried out at Research Farm, Department Agriculture, Maharishi Marka...

A large body of research has documented the effect of seed priming ongermination, emergence and crop yield. In such research, seed priming has beenfound to have a positive, negative or no effect. Meta-analysis can help tosummarize and interpret a collection of experiments. The aim of this study was toconduct a meta-analysis to synthesize published data from studies addressing theeffect of seed ...

to determine the effect of seed size of sugar beet cultivars on germination and seedling vigor, a study was conducted as a 4×6 factorial experiment based on completely randomized design with 4 replications at seed and plant certification and registration institute, karaj in 2013. the treatments were toucan, dorotea, rasta, sharif, pars, and torbat cultivars and four seed width sizes including 2...
