| dc.description | The document made it possible to understand the principles of acropetal mobility of nutrients through the conductive tissue of plants. It must be emphasized that Acropetal movement is related to movement within the xylem, which is a system of connected tissues of the vascular system, without metabolic activity, but its importance lies in relation to passive water transport, that is, the transpiratory current. It is used for the absorption movement of certain elements such as Calcium, Boron. and its greatest activity is in the root-leaf relationship. Based on the information obtained, it was concluded that the concentration of nutrients in the leaf from an early age to the senescence of the plant declines with time, except for immobile nutrients. This is probably due to the fact that there is a change in the proportion of certain tissues with age, such as the increase in the proportion of structural tissues and reserve substances. In perennial crops the concentration of nutrients in leaves and other organs fluctuates with seasonal shoots and growth and fruit development, and also varies between leaves of vegetative and fruiting branches and plants absorb nutrients in different proportions throughout their development cycle. . In general, the absorption rate is lower at the beginning of the growth cycle, increases during fruit development, and falls just before harvest. Also, the absorption rates of individual nutrients vary throughout the growth cycle. | es_ES |

| dc.description.abstract | El documento permitió comprender los principios de la movilidad acropetal de nutrientes por el tejido conductivo de las plantas. Hay que enfatizar que el movimiento Acropetal está relacionado al movimiento dentro del xilema, que es un sistema de tejidos conectados del sistema vascular, sin actividad metabólica pero su importancia radica en lo relacionado al transporte de agua por vía pasiva es decir la corriente transpiratoria. Se aprovecha para el movimiento de absorción de ciertos elementos como el Calcio, Boro, entre otros y su mayor actividad está en la relación raíz-hoja. Por la información obtenida se concluyó que la concentración de nutrientes en hoja desde una edad temprana hasta la senescencia de la planta declina con el tiempo, excepto los nutrientes inmóviles. Esto probablemente se deba a que hay un cambio en la proporción de ciertos tejidos con la edad, como puede ser el incremento de la proporción de tejidos estructurales y sustancias de reserva. En cultivos perennes la concentración de nutrientes en hojas y otros órganos fluctúan con los rebrotes estacionales y crecimientos y desarrollo de frutos, y también varían entre hojas de ramas vegetativas y fructíferas y las plantas absorben nutrientes en diferentes proporciones a lo largo de su ciclo de desarrollo. En general, la tasa de absorción es menor al comienzo del ciclo de crecimiento, aumenta durante el desarrollo de la fruta y cae justo antes de la cosecha. Además, las tasas de absorción de nutrientes individuales varían a lo largo del ciclo de crecimiento. | es_ES |
