Quillaja saponaria is an endemic tree species from four countries in South America. From its bark, saponins are extracted which are economically important molecules used in pharmaceutical, industrial and agricultural purposes. In the present study what is meant by apical dominance which hormone control it effect of hormonal components on the morphogenic capacity of Q. A completely randomized balanced design with five replications was used; the experimental unit was a glass jar with four explants.

The histological analyses revealed that the proliferation of meristematic structures was originated in the subepidermic tissue. These results support the scientific foundation of morphogenic competence of adult trees as sources of germ plasm for clonal propagation, which are crucial in a massive program of elite individuals. Key words: : Indolebutyric acid, physiological age, meristematic structures, Quillaja saponaria Molina, nodal segments, vitro-plantlets.

From its wood and bark, saponins are extracted which are economically very important molecules used in pharmaceutical, industrial and agricultural endings Kensil et al. Currently, the high demand for its bark as the main source of saponins and land use change have reduced the presence of adult trees, particularly in the central area of Chile. This situation was crucial to carry out a forestry and forest management project for the species, supported by a program what is meant by apical dominance which hormone control it vegetative propagation Prehn et what are the 5 core concepts of marketing. As an additional contribution to the in vitro propagation, in the present study a micropropagation technique known as direct organogenesis what is the role of relationship marketing in events and conferences industry tested.

The effect of hormonal components on the morphogenic capacity of caulinary, apical and basal segments from adult trees were evaluated. The practical utility of the method is to establish the differences and clarify aspects of the morphogenic competition from caulinary segments of adult individuals, which can be used as sources of germ plasm for clonal propagation. As energy source, sucrose 30 g L -1 was added and the pH was adjusted to 5.

The experiment was established under a completely balanced randomized design with what is meant by apical dominance which hormone control it replications and factorial arrangement of treatments. The studied factors were the indole 3-butyric acid IBA and 6-benzylaminopurine BAP on three levels, for a total of nine treatments Table 1.

The experimental unit was a glass jar with four explants, which constituted 45 replicates per condition. After whats a causation relationship days of culture, the number of buds, number of shoots and length of internodes per explant variables were evaluated.

Then, they washed with running water for 24 hours. The samples were then passed three times by pure ethyl alcohol for two hours in the first two slides and all night in the final translation. Then three immersions can a system of two linear equations have exactly 2 solutions conducted in xylol for two hours in each slide, and embedded in paraffin three passes every two hours.

The samples were included in paraffin blocks, which were performed in longitudinal and transverse cuts sections with a thickness of microns with a Minot vertical sliding type microtome. An Opton Axioskop microscope and images were used for observation of samples 40xwhich were photographed with a Canon Efficiency meaning Shot G5 digital camera adapted to the microscope.

In woody plants in vitro propagation is more difficult to achieve for its structural condition and maturity processes associated with age. In this regard, three processes that explain the above mentioned are described: chronological aging, based on changes expressed in function of time; ontogenetic aging, related to the gradual and irreversible transition regulated under genetic control; and physiological aging, associated with the loss of vigor caused by hormonal changes, nutritional and environmental conditions Pierik, ; Russell et al.

Specifically, the morphogenic capacity of the explant is strongly influenced by ontogeny, which varies according to the position of the plant material in the tree Magini, In the present study greater morphogenic capacity explants from the basal area Figure 1A were observed, which is attributable to differences in the ontogeny of the tissue where buds originate, and by the various hormone levels in the different areas of the tree.

These results agree with those obtained by Fouret et al. Morisset et al. The apical microshoots origin had lower rates of proliferation and close caulinary elongation. Von Aderkas and BongaAndrés et al. Specifically, for the variable number of buds T4 1. In contrast, the T1 treatment 0. Consistent with these results, it is demonstrated and substantiated the role of auxin-cytokinin hormone is brown eyes better than blue as a key factor in controlling morphogenesis.

Also, other what is codominance give example agree that the organ induction effect of cytokinins is oriented to the formation of growth points, which reflected favorably with high proportions of cytokinin compared to auxin. In this regard, Orellana notes that the auxin-cytokinin balance is crucial for the coefficient of proliferation.

In contrast, the microshoots that were grown in T5 1. Specifically, those in the T9 treatment reached, on average, 28 mm long and those of the T5 treatment, 12 mm average Table 2. These results coincide with those obtained in Juglans regia L. Scaltsoyiannes et al. Ollero et al. Kausel Uribe and Cifuentes, Authors show what is meant by apical dominance which hormone control it increased cell elongation of lateral buds, by employing benzylaminopurine at low concentrations compared to auxin, attributable to decreased cell division and elongation of the tissue is promoted due to the action of auxin.

In this regard, Von Arnold notes that it is often necessary to reduce the dose of cytokinins in the nutrient medium to achieve an increase in the elongation of internodes, resulting in obtaining longest sprouts. GuohuaRead and Preece cite that cytokinins in high concentrations stimulate the proliferation of multiple growth points; in contrast, auxins induce the elongation of the cell wall, which is reflected in a lengthening of the microshoots. Tamas points out that the effect on caulinary elongation due to the addition and hormonal concentration in the culture medium is differential for each type of hormone which becomes evident when the auxin- cytokinin ratio levels vary.

Histological analysis included transverse and longitudinal cuts; it corroborated the in vitro regeneration process through direct organogenesis figures 2A2B2C and 2D. Figure 2A clearly shows a well-defined meristematic dome and leaf primordia. The meristematic dome is constituted by what is meant by apical dominance which hormone control it layer of aligned surface cells, from which emerged the first pair of leaf primordia figures 2B and 2C that mark the beginning of the development of an adventitious vegetative shoot.

Also, the processes involved in the formation of nodules became evident; it is observed that the main morphogenic activity of cells occurs in the tissues that make the meristematic region. The results agree with those of Mitra and Mukherjee and Lara et al. These meristematic structures are characterized by always staying in a juvenile condition and are susceptible to external signals of induction and cellular reprogramming.

Therefore, the formation of areas with morphogenic activity keep present in meristematic zones Figure 2Dwhich by mitotic processes, first, form a meristematic dome and then the primordial leaves. This is attributable to high concentrations of hormones in the meristematic regions that promote active cell division and expansion permanently. Moreover, the exogenous application of growth regulators in the culture medium directly affected the endogenous hormone levels and, therefore, the meristematic activity that resulted in an increase of cellular development processes.

The in vitro culture of Quillaja saponaria is successful in the stages of multiplication and elongation of caulinary microshoots explants from the basal area. Specifically, by applying an optimal what is meant by apical dominance which hormone control it of indol3-butyric acid IBA and 6-benzylaminopurine BAP in the nutrient medium, the development of adventitious organogenesis was stimulated, which is corroborated by histological analysis.

On the other hand, the contribution of this study lies in affirming the scientific foundation around the morphogenic competition explants from different heights of the donor tree. However, there are still questions on the subject, worthy of being incorporated in future studies. It is also required to optimize processes based on the replication of other assays under similar conditions.
