In the Colombian Caribbean, research has focused on evaluating the adaptation and management of commercial genotypes and experimental lines, however, their behavior against soil salinization is unknown. The objective of this research was to evaluate the response of some physiological and morphological characteristics of two promising genotypes against salt stress. The relationship between gas exchange, chlorophyll a fluorescence, and growth parameters was modulated as a function of the NaCl concentration. Although stomatal conductance and perspiration did not show a response to salt levels, the reduction in net photosynthesis as salinity increased was not associated with stomatal effects, but rather with a drop in the rate of electron transport, which articulates the absorption of light energy and its conversion into photoassimilates. Therefore, it could be inferred that salinity-stressed S. rebaudiana plants are more sensitive to non-stomatal limitation than to stomatal limitation.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"212 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74155362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in order to understand the local pea growers perception of agroclimatic risk, a participatory mapping experience implemented in the rural area of the municipality of Fusagasuga was performed. Edaphoclimatic constraints and opportunities of the Municipality for pea crop were identified. The exercise started with the dissemination of local climatic data and thematic cartography related to biophysical variables like elevation and slope. Local descriptions of soil characteristics were defined with the community to identify areas with the most and the least limiting soil conditions for pea crop. In addition, the areas with greater susceptibility to water deficit and water excess were identified. The paper emphasizes on the methodological and pedagogical process generated for the identification of agroclimatic risks. The results show how participatory learning empowers communities with information to improve their own knowledge of the territory. This approach contributes to the adaptative capacity to extreme weather events since it provides elements for community organization to face risk. The participatory approach allowed the identification of Aguadita, Bermejal, Tierranegra, La Palma, Bochica, Batan, Santa Lucía, El Guavio y El Carmen as low-risk areas for pea production due to their soil advantages and low occurrence of water deficit and water excess events.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"98 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81187037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solar radiation influences the thermals of Earth's surface. Apart from radiation, the effects of soil temperature (STe) are specific to fruit species and are mainly modified by humidity, soil cover and air temperature. Increasing the STe within an optimal range promotes the growth of roots and plants and increases the absorption of water and nutrients, photosynthesis, transpiration, efficient use of water and microbial processes. These effects have been demonstrated in several studies on fruit trees and on grape vines, citrus, cape gooseberries, Annonaceae, avocados, olives and prickly pears. However, apart from these positive results, an increased STe as the result of global warming can generate water stress and in turn affect the yield and quality of fruit trees. In terms of effects from cultural practices, mulching with black or blue plastic can increase the soil temperature, and white or silver plastic decreases it. When compared to air temperature, increases in STe in the plants physiology and climate impact studies have been little studied. Therefore, this review aimed to make significant contributions to facilitate decision-making with the goal of reducing the effects of global warming, especially on fruit trees.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82272722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective was to analyze the effects of climatic conditions on the productivity of the ‘Valencia’ orange agroecosystems (Citrus sinensis L. Osbeck) previously typified in the department of Meta, Colombia. The climatological variables precipitation (PPT), maximum and minimum temperatures (Tmax and Tmin), wind speed, relative humidity and solar brightness were analyzed in an observation window spanning the years 2013 to 2015. Using the FAO CropWat model, the crop reference evapotranspiration (ETo) was obtained to applied agroclimatic indices. Using the statistical software STATGRAPHICS Centurion XVI v. 16.2.04, an empirical model was proposed that relates productivity according to agroclimatic indices, for the vegetative and reproductive phenological phases. It was found that the proposed empirical model explains 49% (P=0.0233) of the oscillation of productivity in study area agroecosystems. The model, based on agroclimatic indices associated with PPT, ETo, Tmax and Tmin, found that the relationship between productivity and agroclimatic indices is non-linear. It was established that productivity variation is mainly influenced by PPT, the occurrence and magnitude of which determines the volume of production and quality of the fruit. On the other hand, whereas increases in air temperature and the occurrence of water deficits in the pre-flowering and flowering phases positively favor crop production, the same factors produce a negative effect in the setting phase.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87359057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment design used randomized complete blocks with four replicates; the experiment unit consisted of five effective plants per introduction. The evaluated variables were production per plant (PFT) (kg/pl), number of fruits per plant (NFT), and average fruit weight (AWF) (g/fruit). The genotype×environment interaction and the stability of the 10 genotypes were estimated with the AMMI multivariate model. The environments for T120K and T180K were optimal for the variables associated with production (PFT, NFT and AWF), with IAC1621, IAC426 and IAC1624 being the most promising genotypes per environment on the Farms Tesorito, Montelindo and CEUNP, respectively.

Based on the information, a binary matrix of information was assembled based on the following characters, plant density per hectare, soil type, city, state, average air temperature, planting line spacing, plant spacing on the planting line, implantation date, implantation station, harvesting station, productivity per hectare, days for harvest, liming, fertilization, precipitation and climate. It is evident that in the last 30 years the productivity of cassava in Brazil has been increased, mainly in low-income populations and those located in rural areas. There are prospects for increasing cassava production for fresh sale and industry. The crop is characterized as rustic, highly adaptive, tolerant of water stress and acidic soils, being highly influenced by the climate, rainfall, air temperature, and incident solar radiation.
