Influencia del choque térmico y pre-brotación en el rendimiento de la patata

Thermal shock and pre-sprouting increase the initial development of potato (Solanum tuberosum L.) plants, allowing for earlier harvests. Growing early potatoes without pre-sprouting is not economically viable under Nordic climatic conditions. The aim of this research was to determine how seed tuber pre-planting treatments (untreated, thermal shock and pre-sprouting) influence time to emergence, mean tuber weight, the number of tubers per plant, and yield (including yield dynamics). The main findings of this work were that thermal shock shortened the time to emergence by 2-5 days, while pre-sprouting shortened it by 7-12 days. In addition, thermal shock significantly increased the number of tubers produced, although their mean weight was lower than that of the tubers produced by the pre-sprouted plants. The presprouted tubers provided a very early harvest of large tubers; the harvest time for the thermal shock-treated tubers was a little later. The untreated seed tubers were the last to produce harvestable plants.El choque térmico y la pre-brotación temprana incrementa el desarrollo inicial de plantas de patata (Solanum tuberosum L.), lo que permite una recolección más temprana. El cultivo de patatas tempranas sin pre-brotación no es económicamente viable en las condiciones climáticas de los países nórdicos. El objetivo de este estudio fue determinar qué tratamiento de presiembra de tubérculos para semilla (sin tratar, choque térmico y pre-brotación) influyen en el tiempo de emergencia, el peso medio del tubérculo, el número de tubérculos por planta, y el rendimiento, incluyendo la dinámica del mismo. Se encontró que el choque térmico de los tubérculos acortó el tiempo de emergencia en 2-5 días y la pre-brotación entre 7-12 días. Además, el choque térmico incrementó el número de tubérculos, aunque su peso fue menor que los tubérculos producidos mediante pre-brotación. Un rendimiento muy temprano es posible con tamaño grande de tubérculo aplicando pre-brotación, siendo el periodo de recolección de tubérculos tratados con choque térmico algo posterior. Los tubérculos sin tratar fueron los que mostraron una menor producción

Setting Up Government 3.0 Solutions Based on Open Source Software: The Case of X-Road

Part 2: E-Government Services and Open GovernmentInternational audienceGovernment 3.0, which builds on openness and transparency, sharing, increased communication and collaboration, government reorganization through integration and interoperability, and use of new technologies, is an emerging concept in eGovernance. However, few systems that qualify as Government 3.0 have been described in detail so far. And there is a lack of research on how governments can put in place such systems. This study investigates and characterizes an innovative eGovernment project, based on Open Source Software (OSS), that could be considered as an example of a Government 3.0 project. Therefore, we report from a case study of X-Road, an originally Estonian eGovernment project for creating a data sharing infrastructure, which today is also used in other countries. We present the main characteristics of X-Road from the point of view of Government 3.0, how the X-Road project is organized, compare its organization to other OSS projects, identify who contributes to the project, and point out what challenges are perceived by their stakeholders. We conclude offering some reflections on how X-Road and other Government 3.0 projects can benefit from OSS
