Capturing micro-vibration images in plants caused by homeopathic application
Zanco, Jasper Jose; Boff, Pedro; Domingues, Sérgio; Boff, Mari Ines CarissimiThe use of images, sensors and mathematical algorithms can help in the generation of technical attributes and facilitate the plant health diagnosis. Combined with this, computer vision provides a non-destructive and non-invasive strategy for collecting samples and analyzing plant propagules, provided the experiment traceability. Thus, the objective of this research was to identify signs of homeopathies of Magne...
Actividad peroxidasa y concentración de proteínas en Phaseolus vulgaris l. trat...
Deboni, Tarita Cira; Cargnelutti, Denise; Ghizzoni, Júlia Carolina; Santiago, Gabriela de Melo; Garbin, Egabrieli; Loregian, Alexandre CopattiThe objective of this work was to evaluate peroxidase activity and protein concentration in the defence system expression of common bean Phaseolus vulgaris L., submitted to different potencies of homeopathic preparations. The treatments were composed by: Arsenicum album, Staphisagria, Silicea and Sulphur, in the 6, 12 and 18 CH potencies, compared to the controls. The bean seeds were sown in pots which were kep...
Biophototic in azuki bean seeds treated with ultrahigh dilutions
Zanco, Jasper José; Boff, Pedro; Werner, Simone Silmara; Boff, Mari Ines CarissimiSeed analysis is usually performed by destructive samples with time-consuming methods. Treatments that improve seed vigor are suggested based on bioassays and protocols for most plants. This includes the use of images to assess quality and pro- vide information that supports decisions. However, instrumental cost has not made these technologies widely used. The objective of this research was to study biophotonic...
Foraging behavior of leaf-cutting ants Atta sexdens piriventris Santschi, 1919,...
Giesel, Alexandre; Boff, Mari Inês Carissimi; Fernandes, Patricia; Boff, PedroIn the Microregion of Campos de Lages, Santa Catarina, the edaphoclimate conditions, associated with the typical vegetation of this region may particularize the foraging behavior of leaf-cutting ants Atta sexdens piriventris, unlike those already reported for other locations. This work aimed to study the bio-ecology of foraging A. sexdens piriventris naturally occurring in the Microregion of Campos de Lages. T...
Influence of the homeopathic preparation of shell lime on thrips and yieldof on...
Gonçalves, Paulo Antônio de Souza; Boff, Pedro; Boff, Mari I. CarissimiThe objective of this research was to evaluate the effect of a homeopathic preparation of shell limestone on the incidence of Thrips tabaci Lind. (Thysanoptera: Thripidae) yield and bulb mass of onion in organic production system. The experiment was carried out at the Epagri Experimental Station in Ituporanga, from August to December 2007. The cultivar used was Epagri 362 (Crioula Alto Vale). The experimental d...
Damage and foraging preference of leaf cutter antes on willow crops
Casa, Jamille; Boff, Mari I. Carissimi; Rech, Tássio Dresch; Boff, PedroDamage due to the leaf cutter ants on willow crops has caused losses on yields and on quality of sticksused for handcrafting, because it induce lateral branches. This research had the objective to find the critical stage for losses and mortality of Salix viminalis due to leaf cutter ants, Acromyrmex spp., and the preference of ant to foraging willow clones. Field essays were conducted on willow crops planted in...
Phytogeography of feijoa in the Planalto Serrano Catarinense region
Lorenzini, Artur Raimundo; Carissimi Boff, Mari Inês; Dresch Rech, Tassio Dresch Rech4; Boff, PedroFeijoa (Acca sellowiana) is a native fruit occurring abundantly in the Planalto Serrano Catarinenseregion. This study was carried out in order to characterize the phytogeography of feijoa and to assess its biological interaction in the natural occurrence ecosystem. Twenty-six scientific excursions were carried out over the Planalto Serrano Catarinense region during 2004/05 and comprised 159 sample points with p...

Míldio da cebola: descrição e manejo
Wordell Filho, João Américo; Boff, PedroO míldio da cebola encontra-se amplamente disseminado, com maior importância em regiões de clima temperado, onde períodos de temperaturas amenas, alta umidade relativa e baixa luminosidade são freqüentes. Nas regiões tropicais ou subtropicais, a ocorrência de míldio tem sido verificada durante a época mais fria do ano. Perdas de até 60% na produção de bulbos têm sido registradas em paises e perdas variadas em ...
