Optimal temperature for germination and seedling development of cowpea seeds
Temperature is one of the climatic elements that affect most the germination process and seedling development. Thus, the objective of this study was to evaluate the germination and seedling development of cowpea cultivars under increasing temperature. The seeds of the cultivars Acauã, Carijó, Guarib...

| description | Temperature is one of the climatic elements that affect most the germination process and seedling development. Thus, the objective of this study was to evaluate the germination and seedling development of cowpea cultivars under increasing temperature. The seeds of the cultivars Acauã, Carijó, Guariba, Gurguéia, Itaim, Juruá, Pajeú, Potengi, Pujante, Rouxinol, Tapahium, and Tumucumaque were kept in germination chamber at temperatures of 20, 25, 30, 35 and 40°C, with photoperiod of 12 h. Cowpea seeds have optimal germination performance and seedling development at temperatures in the range of 30.49 - 35.48°C. The cultivars presented germination percentage above 91% under 40°C, however, the seedling were abnormal. The temperature of 20°C provided germination above 96%, but with a longer period to germinate. The temperature range between 30 - 35°C favored the germination speed index, average time, and seed germination speed, with optimum temperatures varying between the cultivars. The highest rate of normal seedlings was observed at temperatures between 25 and 35°C. |

La temperatura es uno de los elementos climáticos que afectan la mayoría del proceso de germinación y el desarrollo de las plántulas. Por lo tanto, el objetivo de este estudio fue evaluar la germinación y el desarrollo de plántulas de los cultivares de frijol caupí a temperatura creciente. Para este propósito, las semillas de los cultivares Acauã, Carijó, Guariba, Gurguéia, Itaim, Juruá, Pajeú, Potengi, Pujante, Nightingale, Tapahium y Tumucumaque se mantuvieron en la cámara de germinación a temperaturas de 20, 25, 30, 35 y 40°C, con fotoperiodo de 12 horas. Las semillas de frijol caupí tienen un rendimiento óptimo de germinación y desarrollo de plántulas a temperaturas en el rango de 30.49 - 35.48°C. Los cultivares presentaron un porcentaje de germinación superior al 91% por debajo de 40°C, sin embargo, no se observó formación de plántulas normales. La temperatura de 20°C proporcionó una germinación superior al 96%, pero con un período más largo para germinar. El rango de temperatura entre 30 y 35°C favoreció el índice de velocidad de germinación, el tiempo promedio y la velocidad de germinación de la semilla, con temperaturas óptimas que varían entre los cultivares. La tasa más alta de plántulas normales se observó a temperaturas entre 25 y 35°C.
