Peach tree thinning is essential for harvesting quality fruits and maintaining balanced fruit production for several years. Manual thinning of peach trees requires a large workforce, thereby increasing the production costs. Chemical thinning may be an alternative solution, but its efficiency depends on the dose of the chemical and plant species. This study aimed to evaluate the effect of different concentrations of metamitron on the chemical thinning of peach trees in southern Brazil. The experiment was carried out in a commercial orchard of peach cultivar ?Sensação? in Morro Redondo, Rio Grande do Sul (RS) state, Brazil. Different metamitron concentrations100 mg L-1, 200 mg L-1, 300 mg L-1, and 400 mg L-1were applied, and manual thinning was carried out 40 days after full bloom (DAFB) and to the treatment where the plants had no thinning. Fruit abscission, effective fructification, total number of plants per plant, production per plant, mean mass, and fruit diameter were evaluated. Applications of 300 and 400 mg L-1 metamitron 40 DAFB promoted high fruit abscission, in addition to decreasing the number of fruits and production. In contrast, applications of 100 and 200 mg L-1 of metamitron 40 DAFB was as efficient in thinning as manual thinning practice with respect to fruit production and fruit mass and its diameter. |

In order to test the performance of bacterial cellulose/polycaprolactone composite (BC/PCL) and pure bacterial cellulose (BC) as tissue substitutes in rabbits? cornea, a superficial ulcer containing 5mm in diameter and 0.2mm deep was made in the right cornea of 36 rabbits, then a interlayer pocket was created from the basis of this ulcer. Twelve rabbits received BC/PCL membrane and 12 were treated with BC membranes, both membranes with 8mm in diameter. The remaining rabbits received no membrane constituting the control group. The animals were clinically followed up for 45 days. Three animals of each group were euthanized at three, seven, 21, and 45 days after implantation for histological examination of the cornea along with the implant. Clinical observation revealed signs of moderate inflammatory process, decreasing from day 20th in the implanted groups. Histology showed absence of epithelium on the membranes, fibroplasia close to the implants, lymph inflammatory infiltrate with giant cells, collagen disorganization, with a predominance of immature collagen fibers in both groups with implants. Although inflammatory response is acceptable, the membranes used does not satisfactorily played the role of tissue substitute for the cornea during the study period. |
