The objective was to characterize growth and development of andean blueberry Vaccinium meridionale Sw., plants, obtained by seed and clonal propagation, from a wild population of the species. Four plants of each type were transplanted to rizhotrons, with glasses on two sides, which allowed the root growth recording. The plants coming from seed spent 1.663 days from sowing to flowering, and those derived from rooted cuttings 1.367 days. In both types, the roots lack root hairs. Also, in both kinds of materials, there was evidence for non alternating periods of root and aerial organs growth, with 6.28 and 7.00 as allometric indexes between the aerial part and the roots for the individuals obtained by sexual and asexual propagation. In spite of the occurrence of periods of increased flower production, after the beginning of the flowering to the end of the research,these organs were detected in both types of materials.There was a greater interplant variability in the growth values obtained in the sexual plants than those of the clonal ones.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"14 1","pages":"65-77"},"PeriodicalIF":0.2,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408452","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}

Hass planted in the Colombian Andes. Climate data for the 2010-2011 period were obtained from six automatic weather stations. Insect activity was monitored by recording the presence of M. velezangeli individuals and fresh damage signals on 12 tagged branches per tree, oriented towards the four cardinal points at low, medium and high tree strata. Relations were established between population indexes and temperature, relative humidity and wind speed by means of Biplot representations and correlation analyses. These analyses were carried out not only between records taken the same day, but also included backward cumulative values of climatic factors, i.e., the sum over a period of days before the assessment. The results suggest that temperature and relative humidity have a direct influence on the insect, while wind speed showed an inverse relationship. This study illustrates how the analysis of climate information can improve our predictive capacity on the establishment of M. velezangeli in avocado crops, which is a key aspect of integrated pest management.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"79-85"},"PeriodicalIF":0.2,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408326","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}

In these conditions the mandarins get the best internal and external qualities.‘Arrayana’ is the main mandarin cultivated in Colombia tropical lowlands (around 04° N). This variety is characterized by a high concentration of the harvest in december and january because it has only one principal bloom in the year (two weeks after onset of rainy season); and an average external quality that prevents it from being highly competitive. Both conditions reduce the profitability of citrus growers in the region. In order to identify and develop mandarin genotypes who obtain outstanding qualities in tropical lowlands, was evaluated at Corpoica La Libertad Research Center (Villavicencio, Meta) the Dancy variety since 2000 (Citrus reticulata Blanco var.Dancy) for vegetative growth, fruit yield, quality and consumer acceptance through a hedonic test. This information was compared with that obtained in experimental field of Arrayana tangerine; both were grafted on ‘Cleopatra’ mandarin rootstock (Citrus reshni hort. ex Tanaka). The outstanding fruit quality of Dancy (TSS: 10,8; TSS/TA ratio: 18,1; fruit weight:145,85 g) and high cumulative production confirms the adaptation of the variety to the conditions of the Foothills of Meta department; while good consumer acceptance, suggests its recommendation to be established as complementary to the Arrayana’s production. The evaluated clone is susceptible to Alternaria which may limit its cultivation in tropical medium lands conditions where the rainfall regime is bimodal and relative humidity can be high.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"16 1","pages":"105-112"},"PeriodicalIF":0.2,"publicationDate":"2015-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68408389","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 plot was laid out and demarcated; then, were identified and measured all individuals with DBH greater than ten centimeters. Accordingly with floristic composition were founded 519 individuals belonging to 72 species, 56 genera and 36 families of woody plants were recorded. Families with highest species richness were Burseraceae (5), Euphorbiaceae (5) and Clusiaceae (5). The main uses of the 72 species were 32 timber, 18 wildlife feeding, 10 watersheds protective nature, five suppliers of wood, three fruits, one dye production and one ornamental. The highest tree recorded for the parcel height was 21 meters reported by individuals in the “chaparro de agua” Panopsis rubescens and “merecurillo blanco” (Licania kunthiana).

The crop management carried out by farmers was characterized and its effect on the white fly presence on three cultivars was evaluated (Choquette, Hass, Lorena). Presence of secondary metabolites on leaves from Hass and Lorena was measured and the effect of their leaf extracts on the mortality and repellency index of whitefly adults was established. There were interactions between crop management and cultivar for the presence of the insect; moderately chemical management had the lowest infestation in all cultivars. The increase in soil fertilization and chemical insecticides increased insect population, and removal of the hemiparasite decreased it. Lorena cultivar had the highest fly preference, insect population increase when there was interaction between cultivar and mature leaves, neutral repellency index, and high percentage of total and non-reducing carbohydrates. The Hass cultivar showed higher amount of coumarins, terpenes and steroids, and high rate of repellency. Lorena attracting the insect is due to the presence of carbohydrates; and Hass repellency is due to the terpene and / or steroids.
