seed reserves are controlled by genetic and environmental condition such as nutrition, temperature, drought stress and light intensity. strong seedling will produce from seeds with high reserves. therefore, in this work that conducted in pot, field(in tabriz university) and lab(in shahrood university of technology) experiments, effect of pre-anthesis nitrogen application and a drought stress du...

OBJECTIVE For the past 2 decades there has been vigorous disagreement over the purported toxicity of Hedysarum alpinum seeds, and whether the consumption of such seeds was a factor in the 1992 death of Chris McCandless, the subject of the book Into the Wild. Our objective was to confirm or disprove the presence of L-canavanine (a nonprotein amino acid known to induce systemic lupuslike symptoms...

This paper systematically studies maize seeds varieties identification technology and algorithms using advanced machine vision technology. A multi-object contour extraction algorithm adapting to maize seeds varieties identification was proposed. Geometric features and color features parameters of maize seeds were defined and analyzed, and a multi-object geometric features and color features ext...

The effect of W92/72 transgenic flax seeds taken from a variety of Linola on the production of SCFA, ammonia and methane by bacteria inhabiting rabbit caecum was studied. The in vitro method was used where caecal contents from rabbits was incubated with W92/72 transgenic or Linola flax seeds, or without any additives (control samples). The total concentration of SCFA was higher in samples with ...

This study investigates the seasonal variation of germination ability of buried seeds of Monochoria vaginalis (Burm.f.) Presl var. plantaginea Solms. The ®eld-collected seeds were buried in a ̄ooded or an upland ®eld and then exhumed monthly. The exhumed seeds were germinated under four temperature regimes. The seeds exhumed from the ̄ooded soil were dormant at the beginning of burial and proceed...

Scatter-hoarding rodents are effective dispersal agents for many plant species. Several studies have shown that rodents repeatedly re-cache seeds. The re-caching process often has a significant impact on final seedling establishment, but the factors determining its occurrence are poorly understood. In this study, we followed the fate of 3564 artificial seeds that varied in size, nutrient conten...

Raffinose family oligosaccharides (RFOs) have been implicated in mitigating the effects of environmental stresses on plants. In seeds, proposed roles for RFOs include protecting cellular integrity during desiccation and/or imbibition, extending longevity in the dehydrated state, and providing substrates for energy generation during germination. A gene encoding galactinol synthase (GOLS), the fi...

how the seeds of delphinium staphisagria promote hair growth in humans is yet to be discovered. this lack of information leads us to the investigation of hair promoting effects of seeds of delphinium staphisagria in vitro. extract prepared from the seed of delphinium staphisagria (esds) - traditionally used for hair loss treatment - was selected and tested for the cytotoxic and angiogenic poten...

The magnetic field (MF) is considered as a biophysical treatment to change the growth and development parameters. Current research was carried out to evaluate the effect of different intensities of MF (0, 45, 60, 70 and 75 mT) on seed germination and some morphologic and physiologic parameters of Rudbeckia hirta L. in dry and humid conditions for 30 min. Results showed that the MF trea...

Orchid seeds, which are produced in abundance, are particularly small and light. Some orchid species are anemochorous, i.e., bear seeds that are dispersed by wind. To characterize the seeds of Japanese orchids, we measured the size of seeds and embryos of 68 Japanese orchid species. Most orchid seeds had a length of 0.3 to 2 mm and a width of 0.07 to 0.2 mm. Embryo length and width were 0.1 to ...
