Innovate method measures chlorophyll content in millet leaves

In order to find other ways to measure chlorophyll in plants, researchers at Shanxi Agricultural University in Jinzhong, China, have established a method for detecting it in millet leaves at different growth stages, based on hyperspectral data. The results of the study were published in the article "Estimation of chlorophyll content for millet leaves using hyperspectral images and a convolutional neural network by attention" in the journal Ciência Rural (vol. 50, no. 3). Traditional methods of measuring chlorophyll are labor intensive, damage plant leaves and cannot be used over large areas. For this reason, the researchers developed this new form of detection and used the method for millet leaves, a forage from the tropical climate that presents good nutritional quality when used as food for birds, pigs and ruminants. The characteristic parameters were extracted based on spectral and image information and the analysis was done with the chlorophyll content, to select the characteristic parameters.

According to researcher Xiaoyan Wang, based on the results of the research, a portable chlorophyll detection device could be designed and implanted in agricultural machines in the future, for online monitoring of the plant's chlorophyll content.

The color of soybean seeds influences its quality: Research in Ciência Rural

In order to evaluate the influence of the presence of green soybean seeds on their physiological quality, researchers from the Universidade Federal de Pelotas (UFPel) and the Universidade de Passo Fundo (UPF) carried out the article “Greenish soybean seeds: effect on physiological quality ”, Published in the Ciência Rural journal (vol. 50, no. 2). For the research, six lots of soybean seeds from Cultivar were used with 0, 7, 8, 16 and 18% of greenish seeds. With them, tests of first germination count, electrical conductivity, field emergence, accelerated aging, emergence speed index, tetrazolium, length, dry mass and seedling growth curve were performed.

After evaluations, it was found that greenish seeds have less viability and vigor due to greater deterioration, since chlorophyll does not degrade and reduces the physiological quality of soybean seeds. In the words of researcher Joseano da Silva, "if the number of greenish seeds in the batch is quantified and it is observed that more than 9% of the batch has greenish seeds, it should be discarded as seeds, that is, it should not be marketed".

"Rare retrobulbar meningioma and optic chiasma in a dog" - Research in Ciência Rural

Researchers at the Universidade Federal de Santa Maria (UFSM) conducted a research based on the case of a 14-year-old Dachshund dog, who had a rare tumor in the retrobulbar region and in the optic chiasm. The case drew the researchers' attention to possible tumors in the affected region, and they published the article "Rare retrobulbar meningioma and optical chiasm in dogs", in Ciência Rural (vol. 49, no. 7).

Upon arriving at the Hospital Veterinário Universitário (HVU), the dog presented drowsiness, head pressing, compulsive walking, and circling to the right side. The professionals did eye, ultrasound and neurological exams that showed a multifocal lesion. The owner of the animal opted for euthanasia. At necropsy, it was found that it was a rare tumor in the retrobulbar region.

CIÊNCIA RURAL BRINGS INFORMATION ABOUT COVID-19

In the midst of the COVID-19 pandemic, in Brazil and worldwide, Ciência Rural sought to bring information to its viewers about the new corona virus. Thus, we contacted the professor and virologist, Eduardo Furtado Flores, about some recurring doubts that the community has regarding Covid-19. There are three videos in this series and, in this first, the professor comments on the manifestation and development of the virus in humans.
He explains that the disease is respiratory and that the contamination occurs through the mouth, nose or eyes. The most frequent symptoms are: fever, dry cough, and muscle fatigue or tiredness. Eventually there may be a sore throat. Watch the full material on Ciência Rural's social media.

CIÊNCIA RURAL BRINGS INFORMATION ABOUT COVID-19 – PART. 2

Following the series of interviews with the professor and virologist, Eduardo Furtado Flores, about recurring doubts that the community has regarding COVID-19, we talked about the virulence of the virus compared to other coronaviruses and about the prediction of the duration of the pandemic.
He explains that we have two or three more coronaviruses that cause common colds. However, this new coronavirus is not the same as these others. COVID-19 is a virus that probably went from bats to humans and, whenever viruses pass from one species to another, it tends to be more aggressive. Do you want to know more about it?

CIÊNCIA RURAL BRINGS INFORMATION ABOUT COVID-19 – PART. 3

To conclude the video series with professor and virologist, Eduardo Furtado Flores, about recurring doubts that the community has regarding Covid-19, we asked about guidelines to prevent Covid-19. Some of them are: avoid agglomerations; whenever you touch a potentially contaminated object, clean your hands with 70% gel alcohol or soap and water and avoid bringing your hands to your face.

The virologist also warns people to be aware of where they are looking for information. It is extremely important to check the veracity and source of the information that is circulating about the coronavirus. According to Eduardo Furtado, one should take into account recommendations given by doctors and professionals in the field, who understand the subject.
