Divergência genética de genótipos de feijoeiro a infestação de Zabrotes subfasciatus (Bohemann) (Coleoptera: Bruchidae)

The aim of this work was to evaluate the genetics divergence of bean genotypes in relation to the oviposition, feeding and development of Zabrotes subfasciatus, determining the degrees of resistance to the weevil. The genotypes used were: IAC Carioca-Tybata, IAC Fortaleza, IAPAR 81, IAC Carioca-Ete, IAC Galante, IAC Harmonia, IAC Una, IAC Diplomata, BRS Supremo and RAZ 49. Tests were performed in laboratory under controlled humidity, temperature and photophase conditions. In free choice test, 10 g of bean genotypes seeds were distributed in circular openings placed equidistant from each other in aluminum trays, where 70 couples were released. The attractiveness was evaluated 24 hours and seven days after the experiment started, and then the number of eggs was evaluated. In non choice test, 10 g of seeds were used where seven couples of Z. subfasciatus, 24 hours-old, were released, remaining seven days, and after the adults retreat, the total number of eggs, viable and unviable eggs, the number and percentage of emerged adults, weight, longevity and period from egg to adult of males and females, sex ratio, dry mass and dry mass consumed by insect were evaluated. In the genotype IAC Harmonia was observed the lower oviposition; RAZ 49 was the most non preference-type resistant for feeding and/or antibiosis-type resistant; BRS Supremo, IAC Carioca-Ete and IAPAR 81 are no preference for feeding and/or antibiosis-type moderate resistant; IAC Galante is susceptible and the other genotypes are highly susceptible to Z. subfasciatus.

Multiple Ornamental Uses of Costus stenophyllus Standl. & LO Williams

Costus stenophyllus or bamboo costus, despite its high ornamental potential, is still little known in the cut flower and ornamental plant market. The bamboo costus is a spiral ginger admired for its beautiful stems that are lined with brown colored alternating bands. This costus has rather straight and upright stems. Conical red inflorescences, which resemble the head of a snake, emerge from the base of the plants. The flowers are light yellow and emerge between the red scales on the rather long-lasting, attractive inflorescences. This study was carried out to evaluate the possibility of using these species as a garden plant, cut flower and cut stem. Thus, the characterization was made based on 28 characters of the plant, the leaves, the flower stem, the flowers, as well as season blooming characteristics and flower postharvest longevity.

Comportamento da cana-de-açúcar em duas safras e atributos físicos do solo, sob diferentes tipos de preparo

The tillage comprises on average 25% of the cost of deploying a reed, so this cost reduction measures are desirable since they do not compromise the quality of the operation and longevity of sugarcane. The objective was to evaluate the effect of different tillage systems in Acrustox, correlating soil physical properties and characteristics of sugarcane agroindustrial plant cane and ratoon cane. We used five types of soil tillage, over experimental design in blocks with five replications. The particle size was measured every 0.1 m to 0.4 m depth, through deformed soil samples collected at the end of the first growth cycle of the culture. For other soil physical properties: bulk density, total porosity and water content, assessments were performed at the end of each cycle, collecting soil samples in layers of 0-0.20 to 0.21-0.40 m, in addition to performing the penetration resistance, using a penetrometer impact. The response of sugarcane depending on the types of tillage was determined from the evaluation of productivity per hectare of stem (TCH), sugar (TPH), the values of pol % cane (AP), sugar total recoverable (ATR) and fiber samples collected at harvest stalk of sugarcane plant and ratoon cane. In the tillage studied, there was a change of the physical attributes of the soil, causing reduced productivity in 2009/2010 crop, compared with the 2008/2009 season. In tillage system of furrowing direct lowest result was observed for TCH, especially in 2009/2010 crop, when the difference with conventional tillage was 20.53 Mg ha(-1).

Accumulated productivity and its genetic association with reproductive traits in females Brahman

Objective. Assessment of genetic parameters for accumulative productivity trait (ACP) and genetic correlations with age at first calving (AFC), between calving interval of first and second parity (BCI1) and longevity (LONG). Materials and methods. 8584 Brahman female records were used with an animal model in multi-trait analysis with restricted maximum likelihood method, implemented using the WOMBAT software. The models considered the fixed effects of contemporary group, parity and weaning weight of first calf covariate, the only random effect was the genetic additive direct. Weaning weight (P240) was included to reduce the effect of selection on the estimation of variance components. Results. The heritability estimates were 0.3 +/- 0.04, 0.11 +/- 0.03, 0.07 +/- 0.03 and 0.24 +/- 0.04 for AFC, BCI1, LONG and ACP respectively. Correlations between ACP and the other features were moderate to high and favorable. Conclusions. ACP can be included in breeding programs for Brahman, and used as selection criteria for its moderate heritability and genetic correlation with reproductive traits.
