This study aimed compare segregating populations of common bean (Phaseolus vulgaris L.) derived from intra and inter-gene pool crosses of elite lines by estimates of some genetic and phenotypic parameters. Four elite lines highly adapted to Brazilian conditions were used (ESAL 686 and BRS Radiante: Andean gene pool; BRSMG Majestoso and BRS Valente: Mesoamerican gene pool). Two intra-gene pool (“A”: ESAL 686 × BRS Radiante; “B”: BRS Valente × BRSMG Majestoso) and two inter-gene pool segregant populations (“C”: BRS Radiante × BRSMG Majestoso and “D”: ESAL 686 × BRS Valente) were obtained. The parental lines, the cultivar Pérola and fifty-five F2:3 progenies of each population were evaluated in the rainy season 2010/2011, and afterwards (F2:4) in dry season of 2011. Estimates of genetic variance ( $\hat{\sigma }_{G}^{2}$ ), heritability on a progeny mean basis ( $\hat{h}_{p}^{2}$ ), heritability realized ( $\hat{h}_{R}^{2}$ ) and gain expected from selection (GS) were obtained at joint analysis, in each population, for the traits number of days to flowering (DTF), 100 seed weight (100SW) and seed yield (SYD). It was observed that for all traits, inter-gene pool crosses (“C” and “D”) showed higher estimates of $\hat{\sigma }_{G}^{2}$ , $\hat{h}_{p}^{2}$ , $\hat{h}_{R}^{2}$ and GS than intra-gene pool crosses (“A” and “B”), which indicates more genetic variability. However, for SYD, the higher variability was associated to lower average of seed yield, showing that even utilizing adapted parents the inter-gene pool crosses are inferior to crosses between lines of the same gene pool. 相似文献

Many authors attribute the antioxidant activity of brewed coffee to its caffeine content. In addition, caffeine intake has
been associated with increased performance during physical exercise. This study analyzed the in vivo effects of drinking caffeinated and decaffeinated instant coffee (8%, w/v) on oxidative stress and antioxidant enzyme activity
in the anterior tibialis muscles of rats subjected to intense exercise. It was observed that exercise induced lipid peroxidation
(estimated using malondialdehyde) and protein oxidation (evaluated by determining the formation of carbonyl groups) in the
muscle (P < 0.05). Decaffeinated instant coffee and caffeine solution did not exhibit antioxidant activity in vivo. Caffeinated instant coffee beverage intake did not induce changes in superoxide dismutase and glutathione peroxidase activities
but was able to diminish lipid and protein oxidation in the anterior tibialis muscles of rats after exercise (P < 0.05), contributing to a reduction in the oxidative stress triggered by exercise. 相似文献

BACKGROUND: A new water‐resistant fire ant bait (T‐bait; cypermethrin 0.128%) consisting of dried distillers grains with solubles (DDGS) as a carrier was developed and evaluated against a standard commercial bait (Advion®; indoxacarb 0.045%) under both laboratory and field conditions. RESULTS: When applying the normal T‐bait or Advion® in the laboratory, 100% of Solenopsis invicta Buren worker ants were killed within 4 days. However, when the T‐bait and Advion® were wetted, 70.6 and 39.7% of the ants were killed respectively. Under field conditions, dry T‐bait and dry Advion® had almost the same efficacy against ant colonies. However, when T‐bait and Advion® came in contact with water, the former's ability to kill S. invicta colonies in the field was only marginally reduced, while Advion® lost virtually all of its activity. In addition, DDGS was also shown to be compatible with a number of other insecticides, such as d‐allethrin, permethrin and pyrethrin. CONCLUSION: Based on its properties of remaining attractive to the fire ants when wetted, combined with its ant‐killing abilities both in the laboratory and in the field, T‐bait is an efficient fire ant bait, especially under moist conditions.

Shrubs can provide an important contribution to the fodder resources for small ruminants in Mediterranean areas, but there is limited information on their feed value, including secondary metabolites and their seasonal differences. This study evaluated the effect of seasonal variation in chemical composition, in vitro digestibility and antioxidant activity of the aerial parts of plants of Cistus ladanifer of two age groups [young plants vs. older ones (2–6 years old)]. Aerial parts of C. ladanifer plants of both age groups were characterized by moderate cell‐wall content [321–410 g NDF kg?1 dry matter (DM)], high levels of phenolic compounds (55·1–106 g gallic acid equivalents per kg DM) and condensed tannins (CT) (32·1–161 g kg?1 DM), low protein content (55–100 g kg?1 DM) and low digestibility (249–315 g of digestible organic matter per kg DM). During autumn and winter, C. ladanifer showed higher protein levels and lower cell‐wall content than in the other seasons. The highest values of phenolic compounds, CT and antioxidant activity were achieved during summer. Young plants showed higher levels of phenolic compounds during spring, summer and winter, and higher CT contents in summer (more than 54 g kg?1 DM) compared to old plants. Aerial parts of C. ladanifer of both age groups may be used as a component of ruminant nutrition, but only as a supplement and associated with other feeding resources to complement its nutritional imbalances. 相似文献

The ecological resilience of abandoned pastures has important implications for the potential of passive restoration in the Brazilian Atlantic Forest, especially in the face of the ambitious restoration targets for this biodiversity hotspot. In the present study, we aimed to investigate the influence of past land-use on natural regeneration in two secondary forests that established on abandoned pastures with different land use histories (Abandoned + Fire—15 years since the last fire event and Abandoned—36 years ago) in a lowland Brazilian Atlantic Forest. Both secondary forests exhibit low resilience for the three analyzed attributes: vegetation structure, richness, and species composition. Secondary forests affected by fire have the lowest values for species richness, aboveground biomass and leaf area index compared to old-growth forests. Secondary forests were dominated by Moquiniastrum polymorphum—Asteraceae, which was absent from the old-growth forests. Fire resistance, capacity to establish in nutrient-poor soils and efficient seed dispersal in human-modified landscapes are important attributes that may explain the dominance of this species. We demonstrate that even in sites considered appropriate for passive restoration a priori (e.g. located in a protected area, 36 years since abandonment and close to old-growth forests), secondary forests exhibited low aboveground biomass and communities were dominated by few species. Therefore, our results highlight the effects of past land-use on natural regeneration and suggest the necessity to use interventions such as enrichment plantings, nucleation techniques and assisted natural regeneration in order to accelerate forest restoration. 相似文献

The aim of this research was to determine the effect of nitrogen (N) availability on wild Rhizobiumnodulation, plant growth and grain yield of the common bean crop. Experiments were conducted in two growing periods, from 2 March to 3 June 2011 (autumn) and from 21 September to 23 December 2011 (spring), in pots using sand as substrate. Nitrogen concentrations of 5.12 (T1), 7.6 (T2), 10.12 (T3), 12.62 (T4), and 15.12 (T5) mmol L?1 were supplied by fertigation. In spring, the grain yield, number of grains and shoot growth of both cultivars reduced by effect of N concentration but in the cultivar BRS Valente they reducedonly in autumn. Number of nodules and root growth decreased in both cultivars while N concentration increased in the plant tissues. Nitrogen fertilization is not required to the common bean and its use inhibits nodulation. The increased availability does not enhance plant growth and grain yield. 相似文献

Amyotrophic lateral sclerosis (ALS) is a progressive, lethal neuromuscular disease that is associated with the degeneration of spinal and brainstem motor neurons, leading to atrophy of limb, axial, and respiratory muscles. The cause of ALS is unknown, and there is no effective therapy. Neurotrophic factors are candidates for therapeutic evaluation in ALS. Although chronic delivery of molecules to the central nervous system has proven difficult, we recently discovered that adeno-associated virus can be retrogradely transported efficiently from muscle to motor neurons of the spinal cord. We report that insulin-like growth factor 1 prolongs life and delays disease progression, even when delivered at the time of overt disease symptoms. 相似文献

Research has addressed the valuation of hunting and game species according to their extractive value, using both market and non-market methodologies. This study provides a new perspective to estimate environmental prices of game animals based on game hunting leases, population dynamics, the assumption of a steady state, and the use of the residual valuation method. This, in turn, allows the calculation of the contribution of game animal stock to total income from hunting and the value of game animal stock by species, sex, and age. These values are estimated in a manner that is consistent with the exchange value of national accounts, allowing improvement of game species valuation in ecosystem accounting. 相似文献
