Abstract

The objective of this study was to evaluate the influence of irrigation systems and water depths on physiological, biochemical and production processes of pear trees grown in the Brazilian semi-arid region. The experimental design was randomized blocks, with 2 × 4 factorial scheme, corresponding to two irrigation systems (drip and microsprinkler) and four irrigation depths (60, 80, 100 and 120% of the crop evapotranspiration - ETc), with four replicates. Water deficit and excess applied to plants are harmful to gas exchange as well as to biosynthesis and accumulation of carbohydrates, amino acids and proteins in leaves, compromising the cultivation cycle of pear plants grown in the Sub-Middle São Francisco region. The irrigation depth of 91.8% ETc promotes the highest production of pear (18.49 kg plant-1) under drip and microsprinkler irrigation systems, under the edaphoclimatic conditions of the Sub-Middle São Francisco region. RESUMO O objetivo deste trabalho foi avaliar a influência de sistemas de irrigação e lâminas de irrigação sobre processos fisiológicos, bioquímicos e produtivos da pereira cultivada no Semiárido brasileiro. O delineamento experimental foi em blocos casualizados, com fatorial 2 x 4, sendo dois sistemas de irrigação (gotejamento e microaspersão) e quatro lâminas de irrigação (60; 80; 100 e 120% da evapotranspiração da cultura - ETc), com quatro repetições. A deficiência e o excesso hídrico aplicados às plantas são prejudiciais às trocas gasosas, bem como à biossíntese e acúmulo de carboidratos, aminoácidos e proteínas nas folhas, comprometendo o ciclo de cultivo de pereiras cultivadas na região do Submédio São Francisco. A lâmina de irrigação de 91,8% ETc promove a maior produção de pereira (18,49 kg planta-1) sob sistemas de irrigação por gotejamento e microaspersão, nas condições edafoclimáticas do Submédio São Francisco.
