Pyrethroid pesticides residues have been frequently detected in soils and have been recognized to contribute to soil toxicity. The phytotoxic impact of pesticides was evaluated in Cucumis sativus (C. sativus) seeds. Percentage of seed germination, root elongation, shoot length and leaf length were considered as endpoints to assess the possible acute phytotoxicity of soil by the exposure to pyrethroid...
The distribution of plastids at the time of microspore and pollen grain development in Gagea lutea (L.) Ker.-Gaw. was analyzed using electron microscopy. It was shown that plastids are not transmitted to the forming generative cell of this species during microspore division. At the vacuolate microspore stage, preceding division, the microspore nucleus takes an acentric position and the plastids gather...
Benzoic acids (BAs) are released by plants through leaching of leaf exudates and rhizodeposition. Most of them exert allelopathic effects. BA OH ring substituents generally caused an increase in germination percentage, whereas OCH 3 ring substituents decreased the percentage of germination. Hydroxy substituents increased isocitrate lyase (ICL) activity, whereas OCH 3 ring substituents...
