Allium ursinum is a medicinal plant from the Alliaceae family is also used in gastronomy as a spice or the leaves can be eaten as such, in salads. For its possible use, our study aimed to determine whether, in various concentrations and at different action times, the extract of Allium ursinum has a cytotoxic effect by the standard Allium test. Concentrations of 25%, 50% and 100% of the extract obtained were tested for action times of 6 and 24 hours. For the extract, we used leaves harvested in April and subsequent...

Urtica dioica is a species of the Urticaceae family and the curative properties of this plant have been known since antiquity. Our study aimed to determine whether, in various concentrations and at different action times, the natural extract of Urtica dioica has positive, negative or neutral effects on mitotic cell division. For the proposed study, we used the standard Allium test and tested concentrations of 25%, 50% and 100% of the extract obtained, at action times of 6 and 24 hours. From the results obtained fo...

Plants have been considered as materials for alternative medicine and sources of pharmaceutical drugs. Despite the therapeutic advantages of medicinal plants, some of their constituents may be potentially toxic, mutagenic, carcinogenic, or teratogenic potentials. Therefore, the aim of our study is to determine the cytogenetic and genotoxic potentials of aqueous extract of Plantago lanceolata regarding quality, safety and efficiency. The cytogenetic effects were studied by the calculation of the mitotic index, by t...

Pollen germination and tube growth of fruit trees are the most important characteristics related to pollen quality. An effective fertilization requires the high rates of germination and fast tube growth. For economic reasons a higher rate of pollen germination is needed in fruit trees. The objective of this study was to investigate the cytological characteristics of pollen grains and analysis the germinative potential and the effect of the different sucrose concentrations on pollen germination and tube growth of s...

The present investigation was done to assess cytomorphologic and cell cycle parameters as indicators of genotoxicity as it is a simpler method and could be suggested for rapid screening of the vast range of agrochemicals used all over the world. The excessive and indiscriminate use of agrochemicals is responsible for increasing the level of pollutants in the soil environment resulting in cellular and molecular damage to the plants. Topas 100EC is a widely employed foliar fungicide for horticultural applications. A...

Food safety has become a component of food quality and arises from the need to protect consumers. This means that products to be sold, must be safe, a requirement which is found both in EU Directions and National Legislation. The Food Hygienic General Direction 93-43- CEE stipulates that the food companies including those of fresh fruits, should create a planned and well informed system called пїЅThe Planning and Achievement of Safety productsпїЅ. The system allows a self-control of their own products based on Haz...

Agriculture seeks to accommodate the needs of quality, the cultivation of land in harmony with the environment, respecting the life and the balance of the ecosystems. In this context the aims of our work were to contribute to the strengthening of the aspects related to the influence of the rotation and fertilizing purposes with nitrogen on the content in nutrients of the soil, of the elements of the fertility and the production of triticum wheat. Also has proposed to achieve a summary report on the experiments of ...
