The study was aimed to determine the gallic acid, rutin and quercetin contents yield of Narli onion genotype (Allium cepa L.,) exposed four different doses (0, 25, 50, 75, 100 mg L-1) silver nanoparticles (AgNPs)for30 days, after planting bulbs, attwo-week intervals. Quercetin, rutinand acid in leaves bulbs plants were determined.While content highest 25 L-1ofAgNPs treatment (575.0 ± 10.39 µg g...

Sister-chromatid exchanges (SCE) were studied in allium cepa L. meristematic cells at the second and third divisions after BrdUrd-substitution during just the first or during the second and third cycles, respectively. The observed SCE nonreciprocal/reciprocal ratios detected at the third division in both experiments, as well as comparison of the lowest SCE frequency observed per cycle and expre...

The fumigant toxicity of various essential oils and selected monoterpenoid components were tested against the adult German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae). Responses varied according to plant material, concentration, and exposure time. High insecticidal activity against adult B. germanica specimens was achieved with allyl isothiocyanate (component of horseradish)...

Вивчено морфологічну будову та васкулярну анатомію квітки Alliumcepa. Виявлено нові морфологічні ознаки вертикальної зональності гінецею васкулярної анатомії квітки, які раніше не використовувались у систематиці родини Amaryllidaceae. Мікроморфологічні препарати 15 квіток Allium cepa виготовили, використовуючи стандартні методи просочення рослинного матеріалу парафіном. Описано виготовлені зріз...
