The objectives of this study were to evaluate correlations between culinary quality traits and minerals in common bean lines considering data from individual and combined experiments; de fi ne the minimum number of experiments that provide high coincidence in identifying signi fi cant correlations; and identify promising traits for indirect selection. For this, seven traits related to culinary quality and the concentration of six minerals in grains of 17 common bean genotypes were evaluated. Pearson’s linear correlation analysis was performed on data obtained from four individual experiments and six combinations of experiments. Twelve of the 13 evaluated traits showed a signi fi cant genotype × environment interaction e ff ect, indicating that the common bean genotypes exhibited di ff erences in culinary quality and mineral concentration when these were determined in di ff erent experiments. Pearson’s linear correlation coe ffi cients vary in signi fi cance, sign, and/or magnitude for the traits analyzed in individual and combined experiments. The use of data from three experiments provides a high coincidence percentage in identifying signi fi cant correlations in Pearson’s linear correlation analysis. Common bean lines with high culinary quality and greater mineral concentration can be indirectly selected based on higher L* values (grain lightness) and higher calcium concentrations.","PeriodicalId":21359,"journal":{"name":"Revista Ciencia Agronomica","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71158716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the objective of this study was to evaluate the morphophysiological and biochemical changes in Enterolobium contortisiliquum seedlings subjected to abiotic stresses. The experimental design was randomized complete blocks (RCB), composed of fi ve treatments, with four replicates, and the experimental plot consisted of twenty plants. From the 31 st day after sowing, when the seedlings reached approximately 15 cm in height, they began to receive the treatments, which consisted of different levels of electrical conductivity of irrigation water (0.3; 2; 4; 6; 8 dS m -1 ) for salt stress and periods of water restriction (0; 4; 8; 12 and 16 days without irrigation) for water stress. The traits evaluated were: plant height, root length, stem diameter, number of leaves, leaf area, total dry matter, Dickson quality index, height/shoot dry matter ratio, total soluble sugars, starch, total amino acids and proline. An increase in the electrical conductivity of irrigation water and days without irrigation compromised the development of E. contortisiliquum seedlings, which was intensified from 2 dS m -1 and four days without irrigation for salt and water stresses, respectively. The mechanism of survival of E. contortisiliquum to abiotic stresses involves reduction in the growth and quality of seedlings, with activation of biochemical defense mechanisms of the species.","PeriodicalId":21359,"journal":{"name":"Revista Ciencia Agronomica","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71157866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water dynamics in unsaturated soils is a complex process that can be explained by the Richards equation.

As such, the aim of this study was to evaluate a 2D numerical model in simulating wate r distribution and wet bulb formation resulting from a subsurface irrigation system, in addition to validating the generated model. The Pearson correlation coef fi cient (r), the coef fi cient of deter mination (R 2 ) and the root-mean-square error (RMSE) were calculated. For each treatment, both during and after irrigation, the model showed a small relative error, high values for R 2 and a positive correlation with the fi eld data.

Gas exchange studies have elucidated the physiological mechanisms underlying plant adaptation to ecosystems with low water availability. Here, we evaluated the variability between and within cactus forage genera Opuntia and Nopalea with respect to gas exchange behaviour. Twenty-one cultivars were used, 16 of which belonged to genus Opuntia , while six belonged to genus Nopalea , particularly, O. cochenillifera . Gas exchange was evaluated in the secondary cladode at 00:00 hours using a portable infrared gas analyser. Net CO 2 assimilation rate, stomatal conductance, CO 2 intercellular concentration, transpiration rate, and leaf temperature were evaluated. Additionally, instantaneous water use efficiency, intrinsic water use efficiency, and instantaneous carboxylation efficiency were calculated. Boxplots were used to assess value dispersion between the genera prior to submitting the data to multivariate analysis of principal components and cultivar-based grouping, and subsequently organizing the species studied in a dendrogram. Variability between the two genera and among cactus forage cultivars was detected for gas exchange. Cultivars were classified into three groups and two main components were identified. Cultivars ‘Verdura’ and ‘Orelha de Elefante Mexicana’ showed higher photosynthetic performance.","PeriodicalId":21359,"journal":{"name":"Revista Ciencia Agronomica","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71157798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate their acceptance of trap nests, and their nesting and foraging behaviour, with a view to understanding the potential of the species for rational breeding. Trap nests were offered, and the females were observed for 16 months to monitor the establishment, building and closing of nests, as well as their architecture and the behaviour of the bees when searching for the resources used to build and provision the nests. The results showed that E. tigrinum performs well in trap nests; prefers cavities with a diameter of around 0.45 cm; depends on other plant resources besides pollen and nectar, such as leaves, fi bres and resins, to build its nest; and remains active throughout the year. The study concluded that the species has the potential for use in agricultural pollination programs; however the observed nesting requirements must be taken into account, both in conservation efforts and in zootechnical exploitation when breeding the bee for agricultural pollination, as both can in fl uence the number of constructed nests and cells, and consequently, the size of the pollinator population.","PeriodicalId":21359,"journal":{"name":"Revista Ciencia Agronomica","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71157933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this study aimed to determine physiological and enzymatic changes during the maturation process of melon seeds of the cultivar BRS Anton, obtained from fruits at different maturation stages and subjected to post-harvest storage, by the action of total proteins and the enzymes catalase, peroxidase, and superoxide dismutase. Melon fruits were grown in a greenhouse at Embrapa Vegetables and harvested at five different times: 30, 45, 60, 75, and 90 days after anthesis (DAA). Thirty fruits were harvested in each season and 15 fruits had their seeds extracted immediately after harvest and the other 15 fruits were stored for 15 days. After processing and drying, the seeds were submitted to the following analyses: germination, first count, protein profile analysis, and activity of antioxidant enzymes (total proteins, peroxidase, catalase, and superoxide dismutase). The activity of the antioxidant enzymes from 60 DAA under storage showed a more orderly behavior, reaffirming the results of physiological tests. It shows that the seeds at this point of physiological maturation are well-formed and drying caused no damage to their cell membranes.","PeriodicalId":21359,"journal":{"name":"Revista Ciencia Agronomica","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71157837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study, therefore, was to determine the optimum plot size for evaluating experiments with the chickpea, in scenarios comprising combinations of the number of treatments, number of replications and levels of precision. Two blank experiments were carried out, comprising eight crop rows, 7 m in length, at a spacing of 50 cm between rows and 10 cm between plants; the six central rows were evaluated, giving a total of 60 plants per row. The index of soil heterogeneity was determined, and the optimum plot size was estimated using the Hatheway method in scenarios formed by a combination of i treatments (i = 4, 8, 12 and 16), r replications (r = 3, 4, 5, 6, 7 and 8) and levels of precision (LSD = 25%, 30% and 40%).

However, the quality of soil management in conservation agriculture systems is highly variable. The goal of this study was to verify whether a no-tillage participatory quality index (PQI) is associated with the physical, chemical, and microbiological attributes of soil. Thus, we sought to validate its use as an indicator of soil management quality. A survey was conducted to assess the agricultural practices of farmers from the western mesoregion of the state of Paraná, Brazil to evaluate the PQI. The quality of soil management for annual crops was related to the PQI, as evidenced by its association with soil physical, chemical, and microbiological attributes. These results confirmed the usefulness of the PQI methodology as a tool for assessing the quality of soil management, demonstrating its sensitivity to short-term changes in management practices. Consequently, this may allow for the monitoring of management quality and inferences about the beneficial effects of the implemented practices.","PeriodicalId":21359,"journal":{"name":"Revista Ciencia Agronomica","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71157996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
