| description | Plant physiology and crop productivity The functioning of the rice plant during different growth stages is analyzed at the individual plant level and as a plant community (crop) and then related to physiological and growth processes that determine yields. In the vegetative phase, processes analyzed were root development, tillering, inhibition or suspension, tillers and yield, and leaf cover. In the reproductive phase, the number of panicles per unit area and the number of spikelets per panicle were analyzed. During the maturation phase, deposits, products, reserves, and lodging were analyzed. Genetic variability is discussed to indicate those traits that can be modified to obtain, for example, increased yields. The effects of the environment on the functioning of the rice plant and crop are also indicated, and the role played by agronomic practices in harmonizing the adaptability of varieties to the environment and the environmental offer of production sites is specified. |

Se analiza el funcionamiento de la planta de arroz individualmente y el de una comunidad de plantas (el cultivo), durante las diferentes etapas del crecimiento de la planta, y se relacionan los procesos fisiológicos y de crecimiento con el resultado final: el rendimiento. En la fase vegetativa se analizan el desarrollo de las raíces, el macollamiento, la inhibición o suspensión, las macollas y el rendimieno, y el manto foliar. En la fase reproductiva se analizan el número de panículas por unidad de área, y el número de espiguillas por panícula. En la fase de maduración se analizan los depósitos, los productos, las reservas y el volcamiento. Se discute la variabilidad genética para señalar los caracteres que pueden modificarse con el fin de obtener, por ejemplo, mayores rendimientos. Se señalan también los efectos del medio ambiente en el funcionamiento de la planta y del cultivo, y se indica el papel que desempeñan las prácticas agronómicas en el ajuste entre la adaptabilidad de las variedades al medio y la oferta ambiental de los sitios de producción. 2010 2017-06-20T09:02:27Z 2017-06-20T09:02:27Z Book Chapter https://hdl.handle.net/10568/82495 es Open Access application/pdf International Center for Tropical Agriculture Riveros, Guillermo; Rodriguez, Nuvia Stella. 2010.
