To illustrate the advantages of germinating Oenothera seeds under experimental conditions over the old practice of sowing upon earth I will give the results for a problem as attacked under the old and new method. In 1914 I germinated on earth seeds from an F1 hybrid plant, 13.35ac, of the cross 0. franciscana X 0. biennis. A sowing of 819 seed-like suctures produced a culture of 402 seedlings, ...

there are several methods to increase crops yield, including use of high quality seeds. seed priming is a simple and low-cost method to increase seed quality, if be done right, will lead to increasing plant performance and yield. seed priming treatment applied before planting to enhance germination parameters, seedling establishment and etc. primed seeds get some physiological and biochemical c...

Two field experiments were carried out to investigate the effects of terminal drought on chickpea grown under water-limited conditions in the Mediterranean-climatic region of Western Australia. In the first experiment, five desi (small angular seeds) chickpeas and one kabuli ( large round seeds) chickpea were grown in the field with and without irrigation after flowering. In the second experime...

Variation in pod and seed yield among twelve cultivars of Bambara groundnut was investigated in 2004 and 2005 cropping seasons. The mean performance revealed that BG7004AS despite its recorded low number of pods per plant, had the highest 100 seed weight, pod width, pod length, seed width and seed length, followed by BG7002AS, BG7009BS and BG70010AS, which had the best yield and yield component...

The objective of the study was to characterize annual ryegrass seed population dynamics, managed for natural re-sowing, in no til systems in rotation with soybean, in different chronosequences An area was cultivated for two years with soybean, left as fallow land for the next two years and then cultivated again with soybean for the next two years. The four chronosequences represented different ...

In evolutionary plant breeding, crop populations with a high level of genetic diversity are subjected to the forces of natural selection. In a cycle of sowing and re-sowing seed from the plant population year after year, those plants favored under prevailing growing conditions are expected to contribute more seed to the next generation than plants with lower fitness. Thus, evolving crop populat...

Abstract The article presents a low-cost method of pre-sowing treatment winter wheat seeds, namely, germ stimulation, immediately before planting in the ground, transmission coherent optical radiation low power. It also results laboratory research showing influence small energy effects fixed wavelength on changes growth and germination seed material, as well development stems root system germin...
