Resumo: | Melon (Cucumis melo L.) is a crop of great socioeconomic importance in regions with semiarid climate, as found in Northeast Brazil. In this region water deficit is a usual condition as well as the main reduction factor of plant productivity. Due to this phenomenon, irrigation techniques are used to make available the amount of water needed for plant production. Therefore, this research evaluated the physiology and fruit production changes of ‘Juazeiro’ Piel de sapo melon plants under different water replacement rates. ‘Juazeiro’ melon was grown under four reference evapotranspiration replacement rates (40, 60, 80 and 100% of ETo) distributed randomly in blocks with 5 replicates. The plants were cultivated in the field, in an experimental area located in the Brazilian Northeast region, under hot and dry semiarid climatic conditions, and during the growing cycle the ‘Juazeiro’ hybrid melon plants were evaluated for leaf area, biomass accumulation, gas exchange, photochemical efficiency of photosystem PSII and production of fruits per plant. Application of water replacement rates of 100% ETo leads to highest growth, net photosynthesis, and fruit yield of 'Juazeiro' melon. Water replacement at 80% ETo can be used for ‘Juazeiro” melon under semiarid climatic conditions, but with small losses in fruit yield. Water replacement below 80% ETo leads to drastic reductions in growth, gas exchanges, quantum efficiency of photosystem II and fruit yield, which impairs melon production in semi-arid climate environments. |

O meloeiro (Cucumis melo L.) é uma cultura de grande importância social e econômica mundial, principalmente em regiões de clima semiárido como o Nordeste brasileiro, onde déficit hídrico é condição comum e considerado o principal fator de redução da produtividade das plantas. Tal fenômeno força a utilização da irrigação como forma de disponibilizar a quantidade de água necessária à produção. Assim, objetivou-se com este trabalho avaliar as variações fisiológicas e produtivas de meloeiro pele-de-sapo submetidos a diferentes taxas de reposição hídrica. O híbrido ‘Juazeiro’ de melão pele-de-sapo foi cultivado sob quatro taxas de reposição da evapotranspiração de referência (40, 60, 80 e 100% da ETo), distribuídas em blocos ao acaso com 5 repetições. As plantas foram cultivadas em campo, em área experimental situada no Nordeste brasileiro, em condições clima semiárido quente e seco, e durante o ciclo de cultivo as plantas de meloeiro híbrido ‘Juazeiro’ foram avaliadas quanto a área foliar, o acúmulo de biomassa, as trocas gasosas, eficiência fotoquímica do fotossitesma PSII e produção de frutos por planta. A aplicação de taxas de reposição hídrica a 100% da ETo proporciona o maior crescimento, fotossíntese liquida e produção do meloeiro ‘Juazeiro’. A reposição hídrica a 80% da ETo pode ser usada para o cultivo do meloeiro ‘Juazeiro’ em condições de clima semiárido, admitindo-se pequenas perdas no rendimento. A reposição hídrica com lâminas inferiores a 80% da ETo promove reduções drásticas no crescimento, trocas gasosas, eficiência quântica do fotossistema II e produção, que inviabilizam a produção do meloeiro em ambientes de clima semiáridos.
