Recently much attention has been paid by horticulturists to light-emitting diodes as a new source of economical and spectral-selective light. The reason is mainly coming from their versatility in handling and mounting, long working time, wattage use efficiency and lower heat production. In this study we examined their potential in promoting seed germination and producing quality flower seedling...

Francisella tularensis is a gram-negative coccobacillus and the etiologic agent of the zoonotic disease tularemia. First described in 1911 in Tulare County, California, it has since been reported throughout the Northern Hemisphere, with natural infections reported among an unusually wide range of vertebrates and invertebrates. In recent years, tularemia has emerged in new geographic locations, ...

Sediment deposition is a common phenomenon in the estuary area. Pot control experiments were conducted to evaluate interaction effects of sediment burial depth and salt stress on seed germination early seedling growth Suaeda salsa (L.) Pall., an pioneer species tidal wetland near Yellow River Delta. The results showed that percentage emergence, emergence rate, height, branch number, shoot bioma...

Asexual propagation through cuttings is an appropriate method used for most ornamental plants. Success in increasing the percentage of rooting, reducing root emergence and increasing proliferation efficiency depends on several factors like plant growth regulators, especially auxins. Rooting of Forsythia × intermedia is difficult and requires specific hormonal treatments and proper cultivation b...

abstract in order to study the sensitivity of seven crops to total herbicide soil residue, an experiment was carried out under controlled conditions in 2009 at the college of agriculture, ferdowsi university of mashhad-iran. in this study 7 crops (pea, bean, lentil, corn, rape, beet and tomato), across 7 simulated soil residual concentration of total herbicide (0, 0.0002, 0.0005, 0.001, 0.002, ...
