Early Effects of Growth Substances

Effects of some growth substances on mitosis.

Radiomimetic action of growth substances, also called hormones, has been demonstrated by several workers Some of the growth substances are used as growth promotors while others are used as herbicides for weed control. As they prove toxic beyond certain concentrations, it is fruitful to study their effects at different concentrations. This paper describes the results of an experiment involving d...

Effects of Nigella sativa Allelochemical Substances on Growth-Inhibiting of Flixweed Compared With Wheat (Triticum aestivum)

The aim of this study was to evaluate the toxicity of black cumin (Nigella sativa) extract on germination and growth of flixweed (Descurainia Sophia) seedlings grown in wheat (Triticum aestivum) fields, isolation and identification of important bioactive compounds of its aqueous extract. Two factorial experiments were conducted in a completely randomized design with three replications. In each ...
