| Abstract This study aimed to establish an alternative treatment for post-harvest storage of Papaya (Carica papaya L.), var “Tainung 1” and to control major diseases at this stage. Two storage place were evaluated (room temperature and cold room); Six treatments (Control, Samurai 40ml/20l water, Serenade® 40ml/20l water, Sanatizer EUPROOFF® 10ml/20l water, EUPROOFF® + Serenade® + Samurai, Serenade® + Samurai), five storage periods (0, 3, 6, 9 and 12 days) and three seasons (December, January and February). Fruit weight loss (FWL), color index, number and size of lesions were evaluated and used to calculate the disease incidence and average of disease incidence. The FWL and index color of fruits were more affected by monthly variation than the treatments,... |

| ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial growth and activity, and their effects on plant mineral nutrition in pomelo (Citrus maxima ) and macadamia ( Macadamia integrifolia ) orchards. The treatments included: 1) control [Glyphosate herbicide (Roundup at 4 l per ha)], 2) manual weed control, 3) mulching with dead leaves from their respective trees (macadamia and pomelo), 4) millet, 5) faba bean, 6) millet + faba bean. All the treatments were... |

| The storage structures of spores of Gigaspora margarita Becker & Hall, an arbuscular mycorrhizal fungus, were analyzed by a transmission electronic microscope (TEM) and electron energy loss spectroscopy (EELS). The spores were hydrated, cryofixed using high pressure freezing, submitted to freeze substitution, embedded and prepared for TEM observations. The cryotechniques revealed that the storage structures in the spores are composed of lipids, electron dense granules (EDG), protein bodies and glycogen particles. The EELS detected the presence of nitrogen (N) and carbon (C) in these storage structures and in Bacteria-like organisms (BLO). Some amount of P was detected in the vacuoles and in BLO. The TEM and EELS techniques indicate the presence of... |
