Four traits were analyzed: green biomass production (g), plant height (cm), tillering number and juvenile period of each individual. The means of the characteristics of each genotype were correlated according to Pearson's correlation coefficient. The Mulamba and Mock index was applied, with a selection intensity of 10%, to choose the superior genotypes. There are high positive correlations between juvenile period, height and green biomass production. The selected population were 23 superior genotypes, based on the application of rank sum resulting in high selection gains for the traits of interest. Finally, the selection of elite stevia genotypes with high production of green biomass, greater insensitivity to length of the daily light period, as well as taller plants, are essential for the continuity of the stevia breeding program on the Brazilian Savanna.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88820044","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 objective of this research was to determine the base temperature (Tb) of the phenological period between fruit set and harvest in Horvin plums and to express this duration in terms of GDD to determine the harvest date. Twenty trees were marked per locality at four different altitudes (2,449; 2,285; 2,215 and 2,195 m) in the municipality of Nuevo Colon, Boyaca. During 2015 and 2016, the dates of fruit set and harvest were recorded. Tb was estimated using different methods, as well as the GDD required to go from fruit set to harvest. The variance showed the best statistical fit between coefficient of variation and standard deviation for estimating Tb, with a high degree of correlation. The Tb for this phenological period was 2.9ºC. The results showed that a mean of 1,528 GDD and 81 days were required to pass from fruit set to fruit harvest.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86767310","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}

Its yields are diminished by phytosanitary problems, being the frosty pod rot caused by the fungus Moniliophthora roreri, the most limiting disease with decreases in production of over 90%. In this study, samples of cocoa leachates from commercial producing farms were characterized and the antifungal activity of sterilized, non-sterilized, and filtered cocoa leachates against M. roreri was evaluated under in vitro conditions, at concentrations of 1, 2, 5, 10, and 15%. Monosporic isolates of the pathogen were obtained from diseased fruits collected from cocoa-producing farms in the municipality of Yacopi in Cundinamarca, Colombia. The effect of leachates on M. roreri conidial germination, mycelial growth, and inoculum production was evaluated. It was found that non-sterilized cocoa leachates at all concentrations caused 100% reduction on the three variables evaluated, while sterilized leachates generated the same effect at concentrations of 10 and 15%. Filtered leachates showed no inhibitory effect on the radial growth of the pathogen, but they caused a reduction of conidial germination of 89.9, 90.5 and 95.9% at concentrations of 5, 10, and 15%. The presence of malic, citric, and ascorbic acids, compounds such as NH4, PO4, and NO3, and elements such as Ca, K, Na, Mg, and Cl in the evaluated leachates was identified using high-efficiency liquid chromatography and physicochemical analysis. This research showed the potential of cocoa leachates, even at low concentrations, for the control of M. roreri, which can be attributed to the action of specific compounds such as those found in chromatographic tests.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81511185","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}

Critical parameters for evaluating the nutritional and physiological status of plants include estimates of photosynthetic pigments such as chlorophylls; however, this is a destructive, expensive and time-consuming method that is not easily accessible for agricultural producers. For this reason, in recent years, several technological solutions have been made available, such as the SPAD-502 chlorophyll index meter, which has demonstrated efficiency in terms of rapid estimates of total chlorophyll content in the field. Therefore, the objective of this research was to evaluate the contents of chlorophylls a, b and total obtained with spectrophotometry and to determine the correlation with the non-destructive method (SPAD) in blueberry plant (Vaccinium corymbosum L.) cultivares Biloxi, Legacy and Victoria, in the vegetative phase under conditions of the municipality of Paipa-Boyaca (Colombia). The data obtained with the SPAD-502 ranged from 57.4 to 62.8 SPAD in the 'Victoria', 61.2 to 68.3 in the 'Biloxi', and 68.2 to 73.1 in the 'Legacy'. The content of chlorophylls a, b and total presented a positive and significant correlation with the SPAD index, with a correlation coefficient (r) greater than 0.91 and adjustment to simple linear regression models with a coefficient of determination (R2) greater than 0.90 in the three cultivars. This confirms the usefulness and importance of using SPAD for non-destructive estimation of chlorophyll content under field conditions.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"18 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82878265","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 objective was to study the behavior of champa fruit during postharvest. Fruit were collected directly from trees when they were 100% yellow; then, they were stored at 22°C and 80% relative humidity. The variables were measured over four days. The fruit presented a climacteric behavior with a drastic increase in respiration on the second day after harvest, accompanied by an increase in ethylene production. Firmness decreased continuously and reached values of 1.5±0.14 N at the end. Weight loss increased and was 7.88±0.45% on day 4. Soluble solids increased until climacteric and then decreased. The pH decreased, and the total acidity increased. The color index increased and reached a value of 2.12±0.80. The polygalacturonase activity increased until the third day and subsequently decreased. The activity of this enzyme was related to the loss of firmness. Citric acid was the predominant acid and increased continuously postharvest. In the end, malic and oxalic acid decreased, and succinic had a slight increase. The predominant sugar was sucrose, followed by fructose and glucose. Sucrose presented a high value (61.42±11.6 mg g-1 of fresh weight) on day 1 after harvest; this value decreased on the second day, remained stable on day 3, and then increased for day 4. Glucose and fructose had the lowest values on the first day, which increased in a representative way on day 2, stabilized on day 3, and again increased until day 4. At this point, they had the highest concentration with 24.75±0.71 mg g-1 for glucose and 42.22±0.96 mg g-1 for fructose. These results contribute to the understanding of the postharvest behavior of this species.","PeriodicalId":21384,"journal":{"name":"Revista Colombiana de Ciencias Hortícolas","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76998909","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}
