High night temperature during maize post-flowering increases night respiration and reduces photosynthesis, growth and kernel number
(Wiley, 2022-03-15)In the last years globally, daily night-time low temperatures have increased more than twice compared with maximum temperatures. There is little evidence about maize growth and yield responses to high night temperature ... -
Light interception, yield, spring regrowth and quality of Chloris gayana under different defoliation regimes
(Taylor and Francis, 2022-02-22)To study the effect of different defoliation regimes on light interception, forage yield, spring regrowth and quality of one of the most expanded species in this region, Chloris gayana, we evaluate combinations of two ... -
Partial and total defoliation during the filling period affected grain industrial and nutraceutical quality in soybean
(Wiley, 2022-01-08)BACKGROUND: Little is known about soybean grain chemical composition response to defoliation. The objectives of our study were: (i) to quantify the impact of different levels and timing of defoliation during the filling ... -
Sistemas de fenotipado para la evaluación de las respuestas al estrés salino en Lotus
(Facultad de Agronomía, Universidad de la República e Instituto Nacional de Investigación Agropecuaria, Uruguay, 2013-06-01)La tolerancia al estrés salino es un carácter complejo determinado por la sumatoria de los efectos de numerosos genes, cuya identificación es necesaria para la definición de estrategias de mejoramiento.
