“…One of the nuclear anomalies identified in meristematic cells of garlic exposed to high concentrations of Quantis was the nuclear dissolution. Some authors consider that the apperance of nuclear dissolution gives cytological evidence for the inhibitory action on DNA biosynthesis during S phase of mitotic cell cycle (Akaneme and Iyioke, 2008;Firbas and Amon, 2014). In this context, the results of our study suggest that at 2.5% concentration, Quantis can have an inhibitory effect on DNA biosynthesis in A. sativum root tip cells.…”

The integration of plant biostimulants use to improve the efficiency of crop production can contribute to increasing the agronomic efficiency. Through this study we aimed to investigate the cytogenetic effects of the Quantis biostimulant on the meristematic cells of Allium sativum (garlic), at different concentrations (1, 1.5 and 2.5%) for 8 and 24 h. The results obtained showed that, at 1 and 1.5% concentration, Quantis induced the increase of the mitotic division intensity in A. sativum cells, both during at 8 and 24 h of treatment, compared to the untreated control variant. This fact suggests that, at the respective concentrations, Quantis improves the growth and development processes of the plant. In contrast, at 2.5% concentration, the index of mitotic division decreased by 36.6% (at 8 h), respectively by 64.9% (at 24 h of treatment), compared to the control. Also, at 2.5% Quantis, some chromosomal aberrations and nuclear anomalies were recorded: sticky and laggards’ chromosomes, C-mitosis, micronucleus, nuclear bud and nuclear dissolution. These results suggest that when is used in high concentrations, Quantis induces some cytotoxic and genotoxic effects on A. sativum, which can disrupt the plant growth.

The need to determine the mutagenic ability of waste waters from pharmaceutical industry is on the rise. With the aid of macro and micro assay of the root tip, this study was carried out to assess the genotoxic effects of varied concentrations of three pharmaceutical effluents (Ciprofloxacin, Arthemetrin and Psuedophedrin) on Allium cepa root tip during mitosis. The chemical evaluation of the effluents confirmed the presence of a few heavy metals with mutagenic potentials (Ni, Zn, Pb and Cu). The experiment carried out in the research and teaching laboratory of the

The aim of this study investigated the effects of 50 mg L-1 green tea leaf extract in decreasing harmful effects of 0.175 M salinity stress on the mitotic activity, chromosomal aberrations, seedling growth (fresh weight, radicle length and radicle number), micronucleus frequency which is the simplest indicator, the most effective of cytological damage and bulb germination of A. cepa L. In only green tea leaf extract medium, the radicle length and radicle number of bulbs were partially reduced compared to the control bulbs germinated in the distilled water medium. While their germination percentage and fresh weight statistically indicated the same values. Besides, the mitotic index and chromosomal abnormalities in the root tip meristematic cells of Allium cepa bulbs germinated in alone green tea leaf extract medium increased compared to germinated control bulbs in the distilled water medium, whereas the micronucleus frequency showed statistically the same value compared to the control. In other words, it can be said that salt stress significantly inhibited the seedling growth and bulb germination of Allium cepa. What's more, it significantly reduced the mitotic index in the root tip meristems of the bulbs and increased the number of chromosomal abnormalities and micronuclues frequency. On the other hand, inhibitory effects of salt on the mitotic activity, seedling growth, bulb germination, chromosomal abnormalities and micronuclues frequency significantly decreased with the application of green tea leaf extract. The germination percentage, radicle lenght, radicle number, fresh weight, mitotic index, micronuclues frequency and chromosomal aberrations of the seedlings grown in 0
