We developed a predictive model using Fourier Transform NIR Spectroscopy to distinguish the types of tannins in different forest species in the Amazon. Samples were obtained from different regions of the State of Amazonas/Brazil, and tests for tannins were performed, including obtaining NIRS spectra. The assembly of spectral data matrices versus analytes of interest was crossed with the results of traditional analyses. In addition, a calibration and validation set was constructed for condensed tannins, hydrolyzable tannins, and samples with no tannins. Finally, the performance of classification models was evaluated for sensitivity, identification index, and errors. The condensed tannin classes were detected in 63% of the species studied, followed by 34% of the species not containing tannin. The discriminant analysis produced groupings of classes, with a hit sensitivity index >90%. The developed model can be applied in studies of ecology, forestry and chemotaxonomy, with a focus on phenolic compounds such as tannins. The proposed methodology has advantages over the reference methods, reflected as a lower need for sample preparation, shorter analysis time, no use of reagents, and, consequently, no generation of waste.","PeriodicalId":10188,"journal":{"name":"Ciencia E Agrotecnologia","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67203634","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}

Microalgae are rich in bioactive molecules and can be produced on a large scale and at a low cost. Therefore, we hypothesized that the microalga Asterarcys quadricellulare (CCAP 294/1), a rich source of free L-amino acids, can increase the growth and yield of tomatoes. To determine the potential of A. quadricellulare, we performed a two-year study by applying A. quadricellulare biomass using a foliar spray on tomato plants. In the first season, weekly applications were performed during the full cycle of tomatoes. The effect of A. quadricellulare biomass of 0.05, 0.15, 0.25, and 0.40 g L-1 on tomato yield was determined through regression analysis. In the second season, the solution of 0.25 g L-1, which showed the best results, was tested on two tomato cultivars using a weekly and a biweekly frequency of application. Both cultivars were positively affected by the application of biomass, which promoted the increase in leaf area and yield, along with higher contents of sugar, free amino acid, and protein. Thus, we determined the role of A. quadricellulare as an effective biofertilizer in tomatoes.","PeriodicalId":10188,"journal":{"name":"Ciencia E Agrotecnologia","volume":"101 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67204394","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 growth-promoting effects of the symbiosis of endophytic microorganisms in plants have been exploited in several crops. This study investigated the effects of Induratia sp. endophytic fungi on the growth and grain yield of seed-inoculated common bean plants. The experiments were conducted in a greenhouse during two growing seasons using a randomized complete block design with three replicates. Growth and yield-related parameters such as plant height, root length, leaf index, number of days for flowering, number of pods per plant, number of grains per pod, mass of 100 grains, and grain yield were evaluated. The grain yield of plants inoculated with Induratia coffeana strains CML 4018 and CML 4020 and Induratia sp. strain CML 4015 increased by 52.5%, 48.9%, and 56.4% compared to the non-inoculated control, respectively. Seed inoculation of common bean plants with endophytic fungi species of the genus Induratia showed a beneficial interaction as indicated by the recorded increase in grain yield. The present pioneering study could provide the means for developing crop management strategies for enhancing common bean crop productivity.","PeriodicalId":10188,"journal":{"name":"Ciencia E Agrotecnologia","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67203718","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}

This study was conducted over two seasons (2019 and 2020). The results indicated that direct grafting on the Paulsen 1103 rootstock recorded the highest grafting success percentage. Moreover, the grafting success percentage increased significantly when Paulsen 1103 was used as interstock between Flame seedless and Freedom rootstock (FI/P/Fr) compared to the grafting success without Paulsen 1103 interstock (FI/Fr). Also, using Paulsen 1103 as interstock between Flame seedless scion and Freedom rootstock (FI/P/Fr) significantly reduced the morphological parameters (shoot length, leaf area and the dry weight of shoots and roots) and physiological parameters of leaf (relative water content, transpiration rate, and stomatal conductance) but significantly increased the leaf chemical content (peroxidase activity, total phenols, total proline, and total soluble sugar content) compared to values of the parameters measured in Flame seedless grafted onto Freedom rootstock (FI/Fr). Peroxidase activity could be used for predicting the degree of compatibility in grapevine grafts.

Thus, the objective of this study was to evaluate the effect of chemical priming with proline and sodium nitroprusside as promoters of increased tolerance to water deficit in P. peruviana plants. Plants grown under well hydrated conditions (FC of 70±5%) were sprayed with proline (10 and 20 mM) or sodium nitroprusside (25 and 50 μM) and evaluated after exposure to water deficit (FC of 20±5%). Plants cultivated under water deficit without pretreatment showed reductions in the variables of water relations, gas exchange and growth. Proline and sodium nitroprusside were effective in maintaining less negative water potential, contributing to improvements in gas exchange, such as CO2 assimilation, stomatal conductance and transpiration. Thus, it was possible to measure greater tolerance to water deficit in pretreated plants and, consequently, greater biomass accumulation. It appeard that pretreatment of proline and sodium nitroprusside can have a priming effect against water deficit in P. peruviana plants.","PeriodicalId":10188,"journal":{"name":"Ciencia E Agrotecnologia","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67203395","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 present work aimed to propose an easy-to-use procedure for the calibration of a chlorophyll hand-held meter based on the NDVI homogeneous zones in a vineyard for the device readings and leaf sampling. We evaluated the wine grape ‘Chardonnay’ growing under drip irrigation in a vineyard located in the Southeast region of Brazil. Readings of the relative chlorophyll indices (a, b, and total) were taken in situ four times throughout the 2019 growing season, with the device placed on two leaves of every 40 pre-selected target plants in two homogeneous zones of NDVI previously defined in the vineyard. Subsequently, the chlorophyll and leaf nitrogen contents were determined in laboratory to relate them to the chlorophyll meter readings through generalized estimation equations. The chlorophyll meter is capable of estimating the levels of chlorophyll a, b and total by the models generated with an error of 0.98, 0.58, and 1.47 µg ml-1 cm-2 for calibration and of 1.03, 0.67, and 1.49 µg ml -1 cm-2 for prediction, respectively.

The experiment was conducted under field conditions, using the randomized block design in a 6 × 2 factorial scheme, corresponding to six strategies of irrigation with brackish water applied in the different phenological stages of the crop: WS - without stress, irrigation with low-salinity water throughout the crop cycle; irrigation with high-salinity water only in the vegetative stage - VE; flowering stage - FL; fruiting stage - FR; and successively in the vegetative and flowering stages - VE/FL; and vegetative and fruiting stages - VE/FR, and two potassium doses (60 and 100% of the recommendation), with four replicates and three plants per plot. In irrigation, water with high (4.0 dS m-1) or low (1.3 dS m-1) electrical conductivity was used. The potassium dose of 100% recommendation corresponded to 345 g of K2O per plant per year. The yellow passion fruit ‘BRS GA1’ was more sensitive to salt stress applied successively in the vegetative and flowering stages and vegetative and fruiting stages, showing reductions in the intercellular CO2 concentration, CO2 assimilation rate, instantaneous water use efficiency, number of fruits, and yield. Irrigation with water of 4.0 dS m-1 in the fruiting stage is a promising strategy, as it does not compromise production.

Seeds in the greenish-yellow or cherry stages, recently harvested or stored for nine months at 10 °C with 40, 30, 20 and 12% water content (wet basis - wb), were submitted to physiological and biochemical quality evaluations, and the Trolox equivalent antioxidant capacity (TEAC) was determined. The germination and root protrusion of coffee seeds from greenish-yellow and cherry fruits were not affected by drying, but seeds harvested at physiological maturity had greater vigor when the moisture content was lower. The quality of coffee seeds decreased during storage, and this decrease was greater in seeds stored with higher water contents. Coffee seeds in the greenish-yellow stage had a higher antioxidant capacity than those in the cherry stage when recently harvested, but there was a substantial reduction in this capacity during storage at both maturation stages. Coffee seed deterioration is related to a reduction in antioxidant capacity, and the isoenzymatic profiles of the antioxidant process are little affected by the seed maturation stage.
