Título:  The action of aminoethoxyvinyglycine (AVG) on apple ('Maxi Gala') leaf abscission in plants infected by glomerella leaf spot (colletotrichum gloeosporioides).

Conteúdo:  Abstract In Brazil, leaf abscission in apple trees can occur prematurely due to infection by Glomerella leaf spot (Colletotrichum gloeosporioides). The extent of leaf fall is correlated with ethylene production resulting from the reaction by the host to prevent the dissemination of the pathogen. The aim of this study was to verify the impact of the aminoethoxyivinylglycine (AVG) on the process of leaf abscission in plants exhibiting Glomerella leaf spot symptoms. The experiment was conducted in the spring of 2011 in ?Maxi Gala?/M9 young apple trees (2 years old) in pots under greenhouse conditions at 22±2°C, with 80±5% relative humidity, (28°30?52?S and 50°52?58?W, 950 m). Plants without disease symptoms were artificially inoculated with C. gloeosporioides, and treatments were applied when the leaves had symptoms of infection. The experiment included 7 treatments with AVG and/or the fungicide Folpet (mg L-1 active ingredient ? a.i.) as follows: AVG 60, AVG 150, AVG 30 + Folpet 120, AVG 45 + Folpet 120, AVG 60 + Folpet 120, AVG 150 + Folpet 120, Folpet 120 alone and the untreated control. Assessments of percentage defoliation were made weekly until 68 days after spraying (das). The results indicated that AVG in doses 60 and 150 mg L-1 resulted in a reduced level of defoliation, compared with the fungicide treated trees, and abscission was equivalent to control at 21 das. After the disease is established and is not controlled by fungicide there was an increase in leaf abscissi... Mostrar Tudo

Título:  Simulation of genetic and environmental interaction of three tropical hair sheep breeds.

Conteúdo:  Abstract: The Texas A&M Sheep Simulation Model was used to examine genetic-environmental interactions (GEI) among Brazilian Somali, Morada Nova, and Santa Ines breeds and type and level of feed supplement in northeast Brazil. Two sets of simulations were conducted to examine effects of different supplement quality (napier grass vs cunha legume) and quantity (napier grass only). The analyses indicated the benefits from supplementing lambs at weaning during the dry season and from supplementing lactating ewes at the beginning of lambing season when forage is scarce. The cunha legume was an effective supplement, but choosing between cunha legume and napier grass is an economic consideration. Increasing the amount of napier grass supplement per ewe from 200 g/d to 400 g/d resulted in a significant GEI (i.e., different levels of response such as lamb mortality rate, lamb weaning weight, and lambing rate for different breeds). The Brazilian Somali was the least responsive, whereas the Santa Ines was the most responsive to supplementation. It was concluded that the level of supplement should be higher for the Santa Ines and Morada Nova than for the Somali. The amount of supplement should be regulated so that it neither substitutes for nor lowers the utilization of the native caatinga forage. None of the breeds was simulated to be superior in all environments. Thus, considering the wide range of resources of individual farmers, any one of these breeds may be the preferred choice, de... Mostrar Tudo
