Cotton is one of the most exploited crops in world, being important for Brazilian Northeast. In this region, use irrigation often necessary to meet water demand crop. Water used from underground wells that have a large amount salt their constitution, which can compromise development crops, so it vital adopt strategies reduce stress effects on plants, such as foliar application hydrogen peroxide. Thus, objective study was evaluate peroxide gas exchange, growth, and production naturally...
:The aim of this study was to examine the drying kinetics Spondias purpurea L. fruits at various maturation stages (I V) using a range mathematical models (Henderson and Pabis, Lewis, Logarithmic, Midilli, Page). Additionally, an assessment resulting flours' quality conducted. The stabilization phase S. fruit commenced 420 min for I III, 480 remaining stages. All employed effectively characterized process, exhibiting R2 values exceeding 0.99, MSD below 0.03, X2 0.0009. Flours demonstrated...
Understanding the leaf area is essential in plant physiology and ecological studies, as it directly influences photosynthesis, transpiration productivity. This study aimed to develop non-destructive allometric models estimate of three species from Caatinga biome: Cynophalla flexuosa, Libidibia ferrea Tabebuia aurea. A total 1293 leaves were collected these species, scanned, analysed using ImageJ software obtain their length, width, actual area. In addition, product length width was...
ABSTRACT The salinity of irrigation water and soil create considerable challenges in agriculture, as they harm the physiological processes growth plants. exogenous application antioxidant compounds, such salicylic acid, can reduce damage caused by salt stress. Thus, this study aimed to evaluate attenuation stress induced acid Ocimum basilicum “Cinnamon”. experiment was performed randomized blocks with five levels (0.5, 1.3, 3.25, 5.2 6.0 dS m-1) concentrations (0, 0.29, 1.0, 1.71 2.0 mM),...
ABSTRACT High concentration of salts in the soil impacts availability water and nutrients essential for plant growth physiology. Therefore, management strategies that can mitigate negative effects salt stress are necessary, such as use hormones. Thus, this study aimed to evaluate effect application melatonin on production aspects radish plants. The experiment was carried out a randomized block design, 3 × factorial scheme, with four replications, considering one per experimental plot....
ABSTRACT Eggplant (Solanum melongena) is widely cultivated. It shows moderate tolerance to water deficit, but suffers yield losses in the arid and semi-arid regions where it grown. The aim of this study was investigate influence zinc oxide nanoparticles (NPZnO), association with plant growth-promoting bacteria (PGPB), on post-harvest quality eggplant subjected deficit. Two irrigation percentages relative potential evapotranspiration-ETo (50 100% ETo) five combinations involving NPZnO or PGPB...
ABSTRACT Salt stress hampers the growth and physiology of nasturtium (Tropaeolum majus), due to biochemical, physiological, anatomical disruptions. The application salicylic acid stands as an alternative alleviate detrimental effects salt stress, but studies on are scarce. Thus, aim present study was assess foliar cultivated under stress. experiment followed a completely randomized design in 3 x factorial scheme, with 0 (no stress), 50 (moderate 100 (severe stress) mM NaCl, 0, 0.5, 1 acid,...
The salinity of irrigation water is one modern agriculture’s major obstacles, as it can damage the plants metabolism and, consequently, its development. Currently there a great demand for substances that may mitigate such effects, salicylic acid. Thus, this study aimed to evaluate effects acid application on watermelon (Citrullus lanatus L.) under stress. experimental design was randomized block design, in an incomplete factorial scheme, with four replications and two per replicate....
The synthesis and phytotoxic activity of a series tyrosol 1,2,3-triazole derivatives are reported herein. Target compounds were synthesized through the copper(I)-catalyzed azide-alkyne cycloaddition reaction (CuAAC), known as click reaction, these tested for on leaves wild poinsettia (Euphorbia heterophylla), fleabane (Conyza sumatrensis), tropical spiderwort (Commelina benghalensis). These three highly noxious agricultural weeds that challenge available weed control methods, including use...
The quality of the seeds is great importance for cultivation plants, however, can be altered by abiotic effects, amongst such, saline stress. Salinity one obstacles faced modern agriculture, alternatives have been researched to mitigate its where it possible mention use salicylic acid. objective this study was evaluate basil (Ocimum basilicum L.) cultivated using applications acid attenuate irrigation water salinity. experimental design a completely randomized complete block in incomplete...

A produção de mudas com altos padrões qualidade requer substratos que disponibilizem características químicas e físicas propícias para tal finalidade.Com isso, objetivou-se avaliar alternativos na pimentas pimentões.Comparou-se os seguintes compostos: substrato comercial (Carolina Soil ® ), areia lavada + casca arroz carbonizada esterco bovino (1:1:1 v/v/v), húmus minhoca Carolina
To investigate the herbicidal potential of 2,5-diketopiperazines (2,5-DKPs), we applied a known protocol to produce series 2,5-DKPs through intramolecular N-alkylation Ugi adducts. However, method was not successful for cyclization adducts presenting aromatic rings with some substituents at ortho position. Results from DFT calculations showed that presence voluminous groups position benzene ring results in destabilization transition structure. Lower activation enthalpies SN2-type were...
ABSTRACT Species of the genus Capsicum, especially peppers, are economically important and widely consumed worldwide. The application animal waste as organic fertilizer is a simple cost-effective technique for applying nutrients to soil. Combining cattle manure with humic substances can stimulate plant metabolism, resulting in increased nutrient absorption assimilation. Therefore, objective this study was evaluate doses combined stimulating metabolism morphophysiological nutritional...
ABSTRACT Cowpea is the third most cultivated legume in world, and its cultivation can be intended for both grains seeds. Plants seed production, when exposed to water deficit, may compromise their physical physiological quality, necessitating development of strategies minimize damage, such as application salicylic acid HumigelPlus® polymer. The objective this study was evaluate polymer concentrations reduce effects deficit on quality cowpea landrace seeds used were sourced from two field...
Green peppers (Capsicum annuum L.) is a fruit vegetable with great culinary versatility, and present important nutritional properties for human health. Water deficit negatively affects quality of green fruits. This study aimed to investigate the influence zinc oxide nanoparticles (ZnONPs), associated plant growth-promoting bacteria (PGPB), on post-harvest subjected water deficit. In an open-field ex-periment, two irrigation levels (50 100% crop evapotranspiration - Etc), four treatments...
