No Vale do São Francisco, os tripes, Frankliniella spp. e Selenothrips rubrocinctus, estão entre as pragas mais prejudiciais para a cultura, por atacarem folhas, inflorescências da mangueira e, principalmente, por depreciarem os frutos para a comercialização. Na busca de alternativas para controle químico dessa praga, realizou-se experimento utilizando-se óleo de Nim (Azadirachta indica A. Juss.). O experimento foi conduzido em pomar comercial, localizado no município de Petrolina-PE. Utilizaram-se plantas da cultivar Tommy Atkins, com quinze anos de idade, no espaçamento 10 x 5 m e densidade de 200 plantas por hectare. |

Drought tolerance was examined in two oil palm hybrids (BRS Manicoré and BRS C 2501) grown in large pots and subjected to long-term drought (57 days) and rehydration. Regardless of hybrids, predawn water potential (Ψpd), net photosynthesis rates, and stomatal conductance decreased similarly upon drought imposition, but the absolute values of these variables were lower in BRS C 2501 than in BRS Manicoré. Overall, drought-induced decreases in activities of key enzymes associated with carbon metabolism, including Rubisco, ADP-glucose pyrophosphorylase, and sucrose-phosphate synthase, were stronger in BRS C 2501 than in BRS Manicoré. Our data suggest that synthesis of starch (and possibly sucrose) was fundamentally limited by a lower substrate availability rather than by enzymatic constraints, particularly until day 34 after suspending watering. Drought stress provoked similar decreases in biomass accumulation in either hybrid; however, BRS Manicoré plants displayed higher total leaf area and root length coupled with greater relative decreases in dry matter of above-ground parts than of roots as compared to BRS C 2501, thereby leading to an increased root-to-above ground ratio in the former. Upon resuming irrigation, the slow recovery of Ψpd preceded the recovery of stomatal conductance and photosynthesis irrespective of hybrid. BRS Manicoré was better able to recover enzyme activities and carbohydrate status than BRS C 2501. In conclusion, both hybrids could tolerate (or survive) the severe drought conditions, but, overall, BRS Manicoré plants were better able to adjust its physiological, morphological, and biochemical traits to cope with drought than did BRS C 2501.
