Reação de híbridos de milho à mancha-de-macrospora

Macrospora leaf spot, caused by the fungus Stenocarpella macrospora, has shown to be frequent and important among corn fields in Brazil. Genetic resistance is one of the main strategies to control corn leaf diseases. In Brazil, there is scarce information on the resistance of hybrids to Stenocarpella macrospora. The aim of this study was to evaluate the reaction of 25 corn hybrids to macrospora leaf spot. The experiment was conducted in 2011, in a greenhouse under controlled temperature and relative humidity conditions. Experimental design was completely randomized, with five replicates, each experimental unit consisting of a pot with five plants. Inoculation was done in the V2 growth stage (two fully expanded leaves), and the whorl of each plant received 2.0 mL suspension of 1.8 x 10(4) conidia mL-1 pathogen. The four used fungal isolates were obtained from infected crop residues at the municipalities Lages and Quilombo, Santa Catarina State, and Campinas do Sul and Vacaria, Rio Grande do Sul State. Disease severity was assessed at 21 days after inoculation in the V4 stage (four fully expanded leaves). No tested hybrid was totally resistant to the fungus S. macrospora. There was a significant difference in the disease severity between hybrids and fungal isolates. Hybrids inoculated with Quilombo isolate showed four reaction groups, while the isolates Vacaria, Lages and Campinas do Sul showed two groups. Some hybrids had varied behaviors against the isolates, suggesting different aggressiveness levels. There were hybrids that showed similar reaction to the isolates, suggesting greater stability for macrospora leaf spot.

Resistência de clones de seringueira à infestação por ácaros

Calacarus heveaeFeres (Eriophyidae) and Tenuipalpus heveae Baker (Tenuipalpidae) can cause heavy defoliation of rubber tree plants. From the perspective of integrated pest management, resistant clones can be an important strategy. The objective of this work was to evaluate the resistance of rubber tree clones to the attack of mites, in an experiment carried out in Votuporanga, SP. The experimental design was a randomized blocks with eighteen treatments and three replications. The treatments were the clones PB 230, PB 243, PB 252, PB 294, PB 306, PB 311, PB 312, PB 314, PB 324, PB 346, PB 350, PB 355, IAC 56, IAC 302, IAC 328, IAC 334, Fx 3899 and RRIM 600. The evaluation of C. heveae and T. heveae populations was performed by counting mites and exuviae presence in six leaflets per plot. The defoliation levels were evaluated with a score scale, varying from 0 (no defoliation) to 4 (above 75% of defoliation). Based on the results, Fx 3899 clone is resistant through non-preference and/or antibiosis to C. heveae. The IAC 56 clone is less susceptible to defoliation caused by C. heveae and T. heveae infestation.

Plantas medicinais abortivas utilizadas por mulheres de UBS: etnofarmacologia e análises cromatográficas por CCD e CLAE

The use of medicinal plants corresponds to an ancient practice, either as an alternative medicine for the cure of several diseases, or as a method of abortion. Nevertheless, the population in general does not know the risks involved in the use of medicinal plants. In this sense, the purpose of the study was to evaluate the consumption rate of medicinal plants by women in a Basic Health Unit (BHU), on order to identify which plant species have been most frequently consumed by them, including during the pregnancy. Through an exploratory questionnaire with 48 women, it was observed that most part of the interviewees had children and the most of them cited Peumus boldus, Baccharis trimera and Cassia angustifolia, which were mainly used for stomach aches or digestives (53%), for colds (23%), menstrual cramps (4%) or to menstruate (2%). The remaining part of the study consisted in the visual and chemical analysis of the plant species cited by the interviewees, including other species that have been popularly used as a method of abortion. Comparative visual analysis of medicinal plants (Group A-C) from four different shops showed the absence of quality control concerning packing specifications and the separation of the plant material to be consumed. The analysis of the chemical profiles of these samples by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) indicated that those species belonging to the Group C were significantly different from those plants having the same identification, except for Peumus boldus, whose samples were similar in terms of chemical composition.
