Conteúdo:  Brachiaria decumbens is the main forage in pastures of several Brazilian regions. The effects of liming and plant age on micronutrient uptake by the forage of a degraded Brachiaria decumbens pasture under restoration process, were studied in São Carlos ? SP, southeastern Brazil, under altitude tropical climate. Experimental design was a random block (100 m2), with 6 replications and 3 treatments. Each block received the following treatment: (a) 0 t/ha of limestone with NK; (b) 2 t/ha of limestone applied on soil surface with NK and maintenance of 1 t/ha per annum; (c) 8 t/ha of limestone applied once on soil surface with NK. Forage samples were collected 14 cm above soil surface, each 36 days in the rain season. Instrumental neutron activation analysis (INAA) followed by gamma-ray spectrometry was the analytical method used to determine the micronutrient content. In some cases, Co Fe, Mn and Zn were negatively affected by increasing limestone doses. The opposite effect was observed for Cl. Decreases of Cl, Co and Mo uptake in forage were enhanced with plant aging.

Título:  Effect of the increase of UV-B radiation on strawberry fruit quality.

Conteúdo:  Abstract: The effect of the UV-B radiation on the latent fungi infection in strawberry fruit, on plant production and on physico-chemical quality parameters of strawberry fruits during postharvest preservation was investigated. The experiments were conducted under field conditions in two seasons during 2012. Thedifferent UV-B treatments were: Ambient solar UV-B; Ambient solar UV-B reduced by 80% [UV-B(-)] and Ambient solar UV-B supplemented with UV-B lamps [UV-B(+)]. An electronic modulation system was used to keep the increase on UV-B rate at constant levels throughout the day. The parameters evaluated were latent infection of fungi, dry matter of plants, physico-chemical attributes, color of the peel and fruit production. There was no significant difference among the irradiation treatments regarding the incidence of Rhizopus nigricans and Botrytis cinerea at both seasons. Independently on the season and the irradiation treatment, the incidence of R. nigricans was higher than the B. cinerea and this was considered the mainpostharvest fungi in the experiment. The incidence of Colletotrichum acutatum was limited to second season and it was higher on UV-B(+) treatment. The irradiation treatments had no influence on the drymatter, fruit production, the physico-chemical parameters and color. A strong correlation of both average temperature and precipitation on the incidence of R. nigricans and B. cinerea three weeks before harvesting was detected on both seasons using the Pearso... Mostrar Tudo
