In this study we evaluated the action of crude aqueous extracts obtained from rhytidome of Hymenaea stigonocarpa (jatobá-do-cerrado) on Allium cepa meristematic root cells in three concentrations: 0.082, 0.164, 0.328g/mL, at exposure times of 24 and 48 h. The slides were prepared by the crushing technique, and cells analyzed throughout the cell cycle, totaling 5000 for each control group and concentration. It was found that all three concentrations, including the lowest which is considered ideal for use, in all exposure times, had significant antiproliferative action on the cell cycle of this test system. For cells under division, we observed a high number of cells in prophase. Therefore, under the conditions studied H. stigonocarpa indicated to be cytotoxic.

A field study was conducted in the fall of 2019 to investigate the potential of Arugula (Eruca sativa Mill) aqueous extract as a growth stimulant in enhancing the growth and yield of Fa- ba Bean (Vicia faba L). The study was conducted using sandy soil at a farm in Abo Esaa town in a plot size of 3X5 m2 with a row spacing of 25cm,which based on a complete randomized design (RCD) with four replications, three treatments were carried out, including no foliar spray with E. sativa extracts (control) and foliar sprayed with 20% and 40% aqueous extracts of E. sativa. Ac- cordingly, Faba Bean (Vicia faba L) plants were foliar sprayed six times with the aqueous extracts of E. sativa at rates of 20 and 40% at vegetative and reproductive stages. The result showed that among these concentrations, the foliar spray of faba bean plants with 40% of E. sativa extracts po- tentially were increased all measured growth and yield traits. The results pointed out that plant height increased by 32%, number of branches by 73%, number of leaves by 95%, number of seeds plant by 89%, leaves, stems, pods and roots dry weight by 92%, 80%, 74%, and 89%, respectively. Thus, the study concluded that E. sativa aqueous extracts could potentially be used efficiently by crop producers as a growth enhancer for faba bean crops because of their productivity, great nutri- tive value, low cost, and environmentally friendly nature.

This study aimed to evaluate the effects of aqueous extracts of dried Phyllanthus niruri L. (stonebreaker) leaves on Allium cepa L. root meristem cells at four concentrations, 0.02 (usual concentration), 0.04, 0.06 and 0.08mg/mL and exposure times of 24 and 48 hours. For each concentration we used a group of five onion bulbs that were first embedded in distilled water and then transferred to their respective concentrations. The radicles were collected and fixed in acetic acid (3:1) for 24 hours. The slides were prepared by the crushing technique and stained with 2% acetic orcein. Cells were analyzed throughout the cell cycle, totaling 5000 for each control and exposure time. The calculated mitotic indices were subjected to the Chi-squared statistical analysis (p<0.05). From the results obtained it was observed that all four concentrations tested had significant antiproliferative effect on the cell cycle of this test system. We also found the presence of cellular aberrations such as colchicined metaphases, anaphasic and telophasic bridges, and micronuclei in the two exposure times for all concentrations evaluated. Therefore, under the conditions studied the concentrations of aqueous extracts of leaves of P. niruri showed to be cytotoxic and genotoxic.
