Resumo: | The increase of CO2 concentrations and temperatures may affect the plant development and production. This study aimed to evaluate the impact of the increased temperature and carbon dioxide concentration on the development of cowpea cultivars. The experiment was conducted in growth chambers, with control of CO2 and temperature. A completely randomized design was carried out, in a 4 x 3 x 2 factorial arrangement [cultivar x temperature (day/night) x CO2], with three replicates. The duration of the cowpea vegetative and reproductive phases was evaluated and, at the end of the experiment, the number of pods per plant, number of grains per pod, seed weight, shoot fresh and dry matter weight were quantified. Temperature affects the development of cowpea cultivars, and the temperatures of 29 ºC (day)/23 ºC (night) lead to a higher seed weight. The increase of CO2 leads to a higher number of pods and seeds and seed weight. The BRS Tapaihum cultivar presented the highest number of pods and seeds and seed weight. In addition, the temperatures of 32 ºC (day)/29 ºC (night) lead to a greater flower abortion in the BRS Pujante and BRS Tapaihum cultivars. KEYWORDS: Vigna unguiculata, climate change, phenology. |

Objetivou-se avaliar o impacto do aumento da concentração de dióxido de carbono e da temperatura no desenvolvimento de cultivares de feijão-caupi. O experimento foi conduzido em câmaras de crescimento, com controle de CO2 e temperatura. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 4 x 3 x 2 [cultivar x temperatura (diurna/noturna) x CO2], com três repetições. Foi avaliada a duração das fases vegetativa e reprodutiva do feijão-caupi e, ao final do experimento, quantificado o número de vagens por planta, número de grãos por vagem, peso das sementes, peso da matéria fresca e seca da parte aérea. A temperatura afeta o desenvolvimento das cultivares de feijão-caupi, sendo que as temperaturas de 29 ºC (dia)/23 ºC (noite) proporcionam sementes com maior peso. O aumento de CO2 incrementa o número de vagens e de sementes e o peso das sementes. A cultivar BRS Tapaihum apresentou maior número de vagens e de sementes e peso de sementes. Além disso, as temperaturas de 32 ºC (dia)/29 ºC (noite) provocam maior abortamento de flores nas cultivares BRS Pujante e BRS Tapaihum.
