A total of 33 sesame genotypes including three checks were grown in Randomized Block Design replications for evaluation yield and attributing traits. Data was recorded different traits from all the viz., days to 50 % flowering, number productive branches, plant height, height 1st capsule bearing node, capsules per plant, seeds capsule, length, inter-node maturity, 1000-grain weight, cent oil yi...

After 120 yr of burial in moist, well-aerated sand, 23 seeds of Verbascum blattaria and two seeds of a Verbascum sp. germinated and produced normal plants (50% germination for Verbascum). After a 6-wk cold treatment, a single seed of Malva rotundifolia germinated also, producing a normal plant (2% germination). Plants were grown to maturity in a greenhouse, and flowering was induced by exposure...

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...

Seed’s dormancy is considered as one of the effective factors in seeds germination and consequently in the growth of seeds of many plant species. Shortening the dormancy period and enhancing the germination percentage in fruit types could be a valuable strategy for the seed researchers and plant nurseries. In this research the seeds of mature fruits of different almond cultivars including late-...

In angiosperms, double fertilization of the egg and central cell of the megagametophyte leads to the development of the embryo and endosperm, respectively. Control of cell cycle progression in the megagametophyte is essential for successful fertilization and development. Central cell-targeted expression of the D-type cyclin CYCD7;1 (end CYCD7;1) using the imprinted FWA promoter overcomes cycle ...

Cereal crop yield is determined by different yield components such as seed weight, seed number per spike and the tiller number and spikes. Negative correlations between these traits are often attributed to resource limitation. However, recent evidence suggests that the same genes or regulatory modules can regulate both inflorescence branching and tillering. It is therefore important to explore ...

Intensive size-selective harvesting can drive evolution of sexual maturity at smaller body size. Conversely, prehistoric, low-intensity subsistence harvesting is not considered an effective agent of size-selective evolution. Uniting archaeological, palaeontological and contemporary material, we show that size at sexual maturity in the edible conch Strombus pugilis declined significantly from pr...

‘Naronut 1R’ (Reg. no. CV-150, PI 693985) is a high-yielding, Spanish-type groundnut (Arachis hypogaea L. subsp. fastigiata var. vulgaris) cultivar with red seed coat and two seeds per pod. The was selected from cross between International Crops Research Institute for the Semi-arid Tropics advanced lines ‘ICGV-SM 90704’ 86715’. Naronut 1R developed rosette disease resistance, late leafspot yiel...

Theoretical and empirical studies suggest that the age of first reproduction (the age at which reproduction begins) can have a substantial influence on population dynamics and individual fitness. Using complete survival and reproductive histories of 428 female yellowbellied marmots (Marmota flaviventris) from a 40-year study (1962-2001), we investigated causes and fitness consequences of delaye...

Question: We asked whether a desert ant population and a community of heteromyid rodents select Dithyrea californica seeds in relation to their size, frequency of seed sizes, and absolute density and thus have the capacity to influence natural selection on seed size. Hypothesis: Following the predictions of optimal diet theory, we hypothesized that seed predators will prefer to prey upon larger...
