| Summary, etc. |
Con el fin de encontrar un indicador morfologico de la madurez fisiologica del grano en trigo (Triticum aestivum L.), se hizo un estudio en Chapingo, Mexico en el que se evaluaron 15 cultivares con caracteristicas contrastantes en altura de planta, precocidad y presencia de aristas. El estudio comprendio dos experimentos. El primero, en campo, donde se evaluaron 9 criterios basados en la perdida del color verde en porciones de la espiga y del pedunculo, mas dos testigos: cinco y diez dias despues de la perdida del color verde en la espiga. El segundo, en laboratorio, donde se evaluo la germinacion de la semilla y el vigor de las plantulas obtenidas de cada uno de los criterios considerados en el primer experimento. Del analisis de los resultados del primer experimento se concluyo que la perdida de color verde en el raquis fue el mejor indicador de la madurez fisiologica del grano, entendiendo esta como la maxima acumulacion de materia seca en ese organo, la cual ocurrio 45 dias despues de antesis en promedio de los 15 cultivares. En el segundo experimento se presentaron porcentajes de germinacion superiores a 90 porciento en semillas cosechadas desde los 25 dias posteriores a la antesis; ademas, se observaron las mayores longitudes de radicula, plumula y plantula en semillas cosechadas 36 dias despues de antesis, lo que sugiere que la madurez fisiologica del embrion ocurre antes de la maxima acumulacion de materia seca en el grano |
