Escribe el mensaje aquí Growth and mechanical impedance. The sinuosity degree of B1 axis in the root of C. The roots did not penetrate sand with a particle size of less than 0. Kosugi, and T.

What are the 5 types of root system of substrate and mycorrhizal fungus on the root and shoot architecture of coffee-shading walnut Cordia alliodora [Ruiz et Pav. Bogota Colombia. ABSTRACT Cordia alliodora coffee-shading walnut is a species of economic importance to Colombia because of its multiple uses for farmers and for reforestation as a timber and industrial resources, mainly in the central coffee region of the country.

The aim of this research was to study parameters of C. Plants were established in Pacho municipality Cundinamarca at an 2, m a. A split plot design with a randomized complete block and three replicates was applied. Within the main plot, we evaluated the substrates soil, husk and compost ; soil and husk ; soil and huskand withing the subplot, the mycorrhizal fungus without fungus, Kuklospora colombianaGlomus manihotis and Wha lacunosa.

Substrate type affected C. Plants transplanted into soil, husk and compost had the best responses in architectural parameters: diameter of the base of the root 7. Since no fertilizer was applied to coffee-shading walnut plants, we conclude that the mycorrhizal thhe facilitated a better use and development of mineral elements present in the substrates.

Las plantas fueron establecidas en el municipio de Pacho Cundinamarca a 2. Bajo el diseño de parcelas divididas con distribución de bloques completos al azar con tres repeticiones, oof evaluó en la parcela principal el sustrato suelo, cascarilla y compost ; suelo y cascarilla ; suelo y cascarillawhat is inductive effect explain en la subparcela, el ade de micorriza sin hongo de micorriza, Kuklospora colombianaGlomus manihotis y Acaulospora lacunosa.

Considerando que no se aplicó fertilización a las plantas de nogal cafetero, los hongos de micorriza evaluados favorecieron una mejor utilización y aprovechamiento de los elementos minerales presentes en los sustratos. Globally, environmental policies and actions attempt to reduce key pressures on ecosystems, the environment and biodiversity, whzt incorporating strategies based on sustainable management of environmental goods and services and, the efficient use of natural resources.

Therefore, the development of the forestry chain will ensure the sustainable production of forest trees and high quality products that meet the domestic demand and reduce the need to import these products CONPES, what are the 5 types of root system In the case of forest species used as timber such as Cordia alliodora Ruiz et Pav. Oken, farmers and forestry companies have difficulties to obtain permanent production of high quality trees to ensure their commercialization, because the environmental component is not included in the planning and development of production systems.

Likewise, systfm are few studies about the plant growth from a dynamic and comprehensive aspect with syxtem morphological and ecological approach Hallé et al. These situations can often be- come limiting factors for the establishment of plantations, whereas plant architecture is the result of the interaction between endogenous growth processes and the constraints exerted by the environment Barthelemy and Caraglio, ; Sussex and Kerk, In Colombia, Cordia alliodora is distributed in altitudes from 0 to 2, m on the Pacific slope, and from 0 to m on the Atlantic oc, with ha planted with this species in the departments of Tolima, Santander, Cundinamarca, Risaralda, Magdalena, Cauca, Valle del Cauca, Meta and Nariño Salazar et al.

In the context of plant architecture, aspects of plant growth and development related to the shape of the plant shoot and root system are considered. This is a dynamic, global approach to growth and is the result of the operation of the plant meristems in response to environmental conditions Perreta and Vegetti, ; Barthelemy and Caraglio,Sussex and Kerk, ; Vester, The body of a plant is formed from repetitive morphogenetic processes that create fundamental architectural units: the cell, with its ability for division allows the establishment of the meristem.

Architectural plant studies are related to fundamental concepts such as architectural modeling, architectural unity and repetition. The architectural model expresses the overall growth strategy and is the set of axes that make up the body of the plant during its ontogeny Perreta and Vegetti, The basic architectural unit structure, which allows the prescription of the plant's body shape, is metamere, formed by the insertion node, the associated leaf or leavesot axillary bud, the internode and in many cases the roots Perreta draw the graph of linear equations in two variables Vegetti, ; Sussex and What eye color is more dominant blue or green, Repetition is the process that allows architectural units repeated partially or completely during ontogeny, in response to environmental conditions, to build the plant body Perreta and Vegetti, ; Barthelemy and Caraglio, The aim of this work was to study parameters of shoot and root system architecture during the first year of development of Cordia explain mutualism with example plants grown in three substrates and inoculated with three mycorrhizal fungi from three systen of previously reported Glomeromycetes for soil in the Colombian coffee zone: Kuklospora colombiana Instituto Venezolano de Investigaciones Científica - IVICGlomus manihotis IVICAcaulospora roott IVIC and a control.

This architectural study on Cordia alliodora is a detailed and comprehensive approach to the development of the plant useful to propose management strategies for reforestation, forest production greenhouses, nurseries for the production of trees with excellent quality shafts, because it points to the best propagation technique, from among those compared in this study, to improve yield and mass production of high quality trees, considering that from the perspective of forest products, size and growth dynamics of the shoot and root system are determinants of the quality of the wood and the trees Di Lucca, ; Garber et al.

The present study on the root and shoot architecture of Cordia alliodora Ruiz et Pav. Oken was carried out during the first year of the vegetative stage. The plants were established in the town of Pacho CundinamarcaBambusa station, owned by Geoambiente, located at 2, m a. The experimental design was a split plot with distribution using a randomized complete block with three replications. Each experimental unit consisted of 90 plants. To establish the field test, C.

When the plants reached 8 cm in length they were transplanted to the substrates, with the application of 3 g of what are the 5 types of root system fungi per bag of homogenized substrate according to the experimental design. At days after transplant datthe roots of the plants were pruned because the evaluated substrates promoted root growth and elongation pruning was done by taking the root from the substrate and cutting the third portion of the main root apex to the neck.

In the vegetative stage of C. Effect of the substrate on the root and shoot architecture parameters in C. Compost is a product used in urban areas for the recovery of degraded soils, containing organic compounds such as humic and fulvic acids that remain in the soil after degradation of organic matter and influence positively biological processes in the soil.

The soil structure significantly improves with the application of compost, since it increases porosity and the water retention capacity, which favors development of what are the three elements of spirituality root apical meristem, facilitates the penetration of the root and thr the capacity of soil water storage.

In addition to root growth, it increases the absorption and transport of nutrients, which leads gypes improve nutritional status of plants Saeboa and Ferrini, ; Shiralipoudre et al. These changes occurred in two successive stages of root growth Fig. With time, at this stage, organogenesis was the result of the operation activity of the undifferentiated cells of the root apical meristem, likewise at this stage, what are the 5 types of root system ramification of the root began Barthélémy and Caraglio, ; Lynch, In the second phase, with exponential growth of the root, which occurred between 82 and dat, processes related to the ramification of the root continued.

On average, there were 20 B2 roots, determining the root polytomy Barthélémy and Caraglio, ; Perreta and Vegetti, ; Lynch, At dat Fig. In the substrate soil: husk: compostthe reduction in RL and B2 was highly significant. This is explained because this substrate led to greater root growth between 52 and dat. Likewise, the plant required more time to recover from this management technique, whereby the RL at dat was lower than the other treatments.

According to several authors, root pruning is a nursery technique that allows control of the root growth pattern. It is usually used to increase the survival of systwm trees. What does making dirt mean pruning has an important potential to control the root system growth at a relatively small volume and to increase the rypes of hairs Low et al. The qualitative characteristics of the root growth response, root form and sinuosity were not influenced by the substrate kf during the dat; then, these traits were considered non-plastic Chambell et al.

The B1 axis of the root showed undefined growth during the dat. The root form of C. The sinuosity degree of B1 axis in the root of C. Although, the degree of lignification of root axis B1 was not affected by the substrate, it increased through the vegetative stage; low until 55 dat, medium until 82 dat, and high until dat Tab. Lignin is a phenolic compound with functional significance for the plant because it confers mechanical support structural rigidity and durability to plant tissues, enhancing lignification of the vascular elements and thereby increasing sap conduction, and it is also associated with the plant defense mechanisms Boudet, ; Cervilla et al.

The shoot architecture parameters: length of shoot, leaf length, leaf dry weight and shoot dry weight, was influenced by the substrate, with the mixture soil: husk: compost showing the highest readings Tabs. Furthermore, this substrate contains rice husks, which provide better drainage and maintain a uniform temperature in the ground, ensuring uniform distribution of soil moisture and allowing good soil aeration Rodríguez, In the initial period of growth until dat, shoot organs in C.

According to Barthélémy and Caragliotypds the active growth phase logarithmicthe shoot apical what is a connections teacher develops new leaves and shoots, which then elongate to form metamere. Subsequently, between and dat, the processes of overlapping and reiteration in metamere allow the construction of the shoot growth model in C.

During leaf ontogeny, the orientation angle of the leaves was affected by the substrates Tabs. Between 55 and dat, leaf lamina development wystem occurred. As the growth cycle of the plants unfolded, dry matter was translocated and accumulated in the leaves as processes of cell division and expansion which are essential for the formation of leaf biomass. Therefore, an increase in LDW was also seen Fig.

During the dat evaluated, the architectural pattern of C. According to the what are the 5 types of root system of activity of the apical meristem shoot in C. Effect of interaction sysyem fungus on the root and shoot architecture parameters in Cordia alliodora. In the interaction of the three substrates: mixture soil: husk: compostsoil: husk and soil: husk with mycorrhizal fungi: HM0 without mycorrhizal fungusKuklospora colombianaGlomus manihotis and Acaulospora lacunosa no statistical differences were seen for any of the variables from the root and shoot architecture evaluated during the dat, because the effects of the application of mycorrhizal fungi did not invoke an immediate response in the architectural parameters evaluated Tabs.

Because no fertilizer was applied to the plants, the results indicate that the evaluated mycorrhizal fungi promoted a better use and development of mineral elements present in the substrates. Therefore, for sustainable use and management of resources in production systems, the use of mycorrhizal fungi is important, which are highly effective in compensating for the reduction or removal of chemical inputs.

Similarly, more mobile ions present in the soil solution such as NO3, P, Zn, Cu and Mo, and to a less extent K and S, are more readily available to the plant as a result of mycorrhizae. The absorption of less mobile mineral elements depends on the area of soil encompassed by the roots of the plant; in this case, mycorrhizal roots have advantages over non-mycorrhizal roots because the external mycelium extends farther than the root hairs Guerra, Root and shoot architectural parameters of C.

In general, plants grown in the wgat soil: husk: compost interacting with Kuklospora colombianaGlomus manihotis and Acaulospora lacunosa presented higher averages than other interactions. Studies conducted to evaluate the effect of combined application of what are the 5 types of root system substrates and mycorrhizal fungi on plant growth claim that organic substrates favor mycorrhizal association Franco et al. Redel et al. This is confirmed by Donoso et al. Systm parameters B2 and RL increased up to DAT due to the evaluated interaction substrate:mycorrhizal fungus, however at dat they degreased as a result of root pruning on the C.

The types of ramification and phyllotaxy of Cordia alliodora were not affected by the interaction substrate: mycorrhizal fungus, which is considered as non-dynamic parameter, the phyllotaxy was determined as lateral Fig. The substrate type affected the response of the shoot and root architecture parameters of C. The application of the mycorrhizal fungi Kuklospora colombiana, Glomus manihotis and Acaulospora lacunosa did not affect the shoot and root architecture parameters of C.
