: Aquaculture is carried out in controlled environments to guarantee the health, growth, and survival of aquatic species, so it is essential to monitor water quality parameters. We designed and implemented a system based on the Internet of Things for monitoring dissolved oxygen and temperature in Amazonian fish larviculture. We based the design of the architecture on four layers: data acquisition, communication, cloud server and application. We carried out the experimental tests with the data collected by the system during seven days of culture of larvae of the species Piaractus brachypomus (paco) in the aquaculture center “La Cachuela”. The values obtained for dissolved oxygen varied between 7.43 ± 0.04 and 7.83 ± 0.02 mg L -1 ; regarding the water temperature, it fluctuated between 19.59 ± 0.45 and 25.45 ± 0.11 °C. We concluded that the system developed for monitoring dissolved oxygen and water temperature displays data obtained in real time, in both cases the values are within the tolerable ranges for the cultivation of this species.

: The Whitsun cactus ( Schlumbergera gaertneri ), native to Brazil, is used as ornamental plant worldwide. Symptoms of anthracnose were identified in plants cultivated in southern Brazil, causing the loss of ornamental value of the affected plants. Thus, the objective of this work was to isolate, characterize and identify the causal agent of anthracnose in S. gaertneri , through morphological and molecular characters. For the pathogenicity test, seedlings were injured with a toothpick and inoculated with a conidia suspension, while the morphological characterization of the causal agent was performed in Mathur culture medium. The Internal Transcribed Spacer (ITS), Actin, β-tubulin, Glyceraldehyde-3-phosphate dehydrogenase and Calmodulin regions were used to molecularly identify the species. The isolates obtained were pathogenic to S. gaertneri , presenting morphological characteristics compatible with species of the genus Colletotrichum . By sequencing the genomic regions, Glyceraldehyde-3-phosphate dehydrogenase, Calmodulin and β-tubulin we identified Colletotrichum karsti and C. siamensis as causal agents of anthracnose in S. gaertneri .

: The use of mulch in the soil attenuates saline stress in corn plants. The objective of this study was to evaluate the effect of irrigation with brackish water in soil under different plant mulches on the productive performance of corn. The study was carried out under field conditions, at the Piroás experimental farm at the Universidade da Integração Internacional da Lusofonia Afro-Brasileira, UNILAB, Redenção, Ceará, Brazil, from August to November 2020. The design was in a 5 × 3 factorial scheme, with four replications, the first factor being the electrical conductivity of the water, in which A1, A2, A3, A4, and A5, refers to 1.0, 2.0, 3.0, 4.0, and 5.0 dS m -1 , respectively, and the second factor the different types of mulch (no mulch - NM; mulch with banana leaves - MBL, and mulch with spontaneous plants - MSP. The following were evaluated: ear mass with and without straw, mass of 1,000 grains, length and diameter of the ear, and yield. Saline stress reduces the mass of 1,000 grains, the length and diameter of the ear of corn, the mass of the ear with and without straw in the presence mulch of weeds and banana leaves. The use of mulch of weeds and banana leaf mulch is more efficient for a smaller reduction in the weight of 1,000 grains compared to the control treatment (without mulch). Banana leaves and spontaneous plants associated with water of 1.0 and 3.0 dS m -1 enabled higher yield compared to the treatment without mulch.
在土壤中使用地膜可以减轻玉米植株的盐胁迫。本研究旨在评价不同植物覆盖条件下微咸水灌溉对玉米生产性能的影响。该研究于2020年8月至11月在巴西塞埃尔雷登地区UNILAB的非洲-巴西整合国际大学Piroás实验农场的野外条件下进行。设计采用5 × 3因子方案，共4个重复，第一个因子为水的电导率，其中A1、A2、A3、A4和A5分别为1.0、2.0、3.0、4.0和5.0 dS m -1，第二个因子为不同类型的覆膜(无覆膜- NM;用香蕉叶覆盖(MBL)和用自然植物覆盖(MSP)。对有无秸秆的穗质量、千粒重、穗长、穗径和产量进行了评价。盐胁迫减少了1000粒谷物的质量，玉米穗的长度和直径，在杂草和香蕉叶覆盖的情况下，有无秸秆的穗的质量。与对照处理(不覆盖)相比，使用杂草和香蕉叶覆盖更有效，可使1000粒重量减少较小。在1.0和3.0 dS m -1水处理下，香蕉叶和自发植株的产量均高于不覆盖处理。

: UV radiation use is currently receiving attention due to concerns about its potential positive or negative effects on the physiological responses of plants, so the goal of this study was to evaluate the influence of natural and artificial ultraviolet radiation (UV-B and UV-C) on soybean seed germination. Initially, the seeds were exposed to UV radiation for different periods of time (0, 1, 2, 4, and 8 hours), with a radiation intensity of 2.5 W m -2 . They were sown on germitest paper and stored in a Biochemical Oxygen Demand chamber set at 25 °C and a 12-hour photoperiod. Tests were conducted for germination (at 8 days), first count (at 5 days), length, and dry mass of seedlings. The results indicated that exposure to UV-B and UV-C (from 1 hour - 9000 J m -2 ) light reduced the germination percentage, the seedling length, and the dry mass of the soybean seedlings. The decrease in root length was observed after 2 (UV-C) and 4 hours (UV-B) of light exposure. It was concluded that, under the conditions of this study, exposing soybean seeds to UV-B and UV-C radiation influenced the percentage of germination and initial seedling growth .
由于担心紫外线对植物的生理反应可能产生积极或消极的影响，因此，本研究的目的是评估天然和人工紫外线(UV- b和UV- c)对大豆种子萌发的影响。首先，将种子暴露在不同时间段(0、1、2、4和8小时)的紫外线辐射下，辐射强度为2.5 W m -2。将它们播种在胚纸上，储存在生化需氧量室中，温度为25°C，光周期为12小时。对萌发(8天)、第一次计数(5天)、幼苗长度和干质量进行了试验。结果表明，UV-B和UV-C光照(1 h ~ 9000 J m -2)降低了大豆幼苗的发芽率、苗长和干质量。光照2 h (UV-C)和4 h (UV-B)后，根长减少。综上所述，在本试验条件下，UV-B和UV-C辐射对大豆种子的发芽率和幼苗初生长率均有影响。
