Cell suspension of Hyoscyamus albus L. were investigated for growth and production of tropane alkaloids in three different media. The effects of sucrose concentration and initial pH were also studied. 2,4- Dichlorophenoxyacetic ...

A population sample of propagules was collected at random from average size A. marina trees growing at "Dhakhira" (Qatar). This sample was then divided into subsamples which were used to detect the effects of light intensity, ...

Biomass and nutrient cycling are evaluated in sites of Ammophita arenaria and Onoaisvaginalis which are among the most common species growing on the coastal dunes of the western desert of Egypt. Both species accumulate N ...

Fresh and exhumed seeds of Ocimuni basilicum L. gave 100 % germination at 13/11-h alternating temperature of 20/10, 32/18, 38/24 and 40/32 °C but did not germinate at constant temperatures. Germination was prevented in the ...

Phaseolus vulgaris and Zea mays seedlings and plants were cultured on quarter-strength Hoagland nutrient medium with or without increasing concentrations of Na^SO^. Sodium sulphate increased the levels of reducing sugars ...

Evaluating the inheritance of growth traits should assist plant breeders in determining its usefulness as a selection criterion for grain yield improvement. Three oat cultivars, 'Stout', 'Lodi' and 'Marathon' were chosen ...
