1. Physiology of the forage cactus cultivate Opuntia stricta (Haw.) Haw under different irrigation frequencies in the Semiarid
ABSTRACT The objective of this work was to evaluate the physiological variables of the cultivar Opuntia stricta (Haw.) Haw in the first cycle and in the regrowth, under different frequencies of drip irrigation, cultivated in the Agreste da Paraíba mesoregion. Therefore, a randomized block design was used, with 2 treatments (irrigation frequencies) and 4 rep

2. Severity of target spot and gas-exchange in tomato cultivated under colored films
ABSTRACT The tomato target spot caused by Corynespora cassiicola may have an important economic impact on tomato production in tropical regions. The objective of this work was to study the effect of different colored plastic films on tomato target spot severity, gas-exchange, and fruit yield. Disease severity, photosynthetic rate, stomatal conductance, trans

3. Pediatric population with cystic fibrosis in the centre of Portugal: candidates for new therapies
Abstract Objectives: Cystic fibrosis (CF) is a severe autosomal recessive disease that results from mutations in a gene encoding the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein, a chloride channel. This study aims to characterize the clinical and genetic features of a cohort of pediatric people with CF (PwCF) in the center of Portugal

4. EFFECT OF THE MIST MICRO-SPRAY TIME ON PHOTOSYNTHETIC SPATIAL HETEROGENEITY OF GRAPE CANOPY
ABSTRACT In grape, high temperatures and low humidity prolong midday depression of foliar photosynthesis and dramatically reduce fruit yield. In this study, we explored the effects of various mist micro-spray treatments on grape photosynthesis at a test site in Shanshan County (N, 42.91°; E, 90.30°), Turpan, Xinjiang, China. We tested four different mist m

5. Physiology and production of yellow passion fruit with hydroabsorbent polymer and different irrigation depths
ABSTRACT The yellow passion fruit is grown under different edaphoclimatic conditions. Irrigation standardizes and increases the development and productivity of the plants. The objective of this study was to evaluate the physiological and productive aspects of yellow passion fruit with application of hydroabsorbent polymer at different irrigation depths. The

6. CHICKEN MANURE AND LUMINOUS AVAILABILITY INFLUENCE GAS EXCHANGE AND PHOTOCHEMICAL PROCESSES IN Alibertia edulis (Rich.) A. Rich SEEDLINGS
ABSTRACT Information on the physiological responses of native plants from the Brazilian Cerrado regarding the use of chicken manure and luminosities are important for their silvicultural management. Thus, aimed to evaluate the effect of chicken manure and luminous availability on the photosynthetic metabolism of Alibertia edulis (Rich) A. Rich. The experimen

7. Irrigation management based on reference evapotranspiration for pre-sprouted plantlets of sugarcane cultivars
ABSTRACT The pre-sprouted sugarcane plantlets (PSP) system aims the production of healthy and vigorous plants in reduced time, reducing the number of stalks needed for planting. Irrigation is used in all PSP system stages and water management plays an important role. Stage 1 acclimation follows the budding stage and lasts for approximately 21 days. At this s

8. Millet irrigation with treated wastewater: Gas exchange response and nutrient accumulation
RESUMO As águas residuárias podem ser consideradas como uma fonte hídrica e nutricional excelente para as plantas cultivadas. Porém, a presença de altas concentrações de sais e de compostos tóxicos pode afetar negativamente as plantações. Avaliou-se o efeito da irrigação com diferentes concentrações de água residuária tratada sobre o acumulo

9. Respostas funcionais foliares de plantas jovens de Hevea brasiliensis submetidas à deficiência hídrica e à reidratação
Resumo A deficiência hídrica é considerada um fator que produz danos significativos durante o período de estabelecimento e de crescimento dos plantios. O objetivo deste estudo foi investigar características morfofisiológicas e bioquímicas de folhas de mudas de seringueira em resposta à deficiência hídrica e, posterior, reidratação. Plantas jovens

11. MORPHOPHYSIOLOGICAL AND NUTRITIONAL BEHAVIOR OF Hymenaea stigonocarpa Mart. ex Hayne (FABACEAE) SEEDLINGS SUBMITTED TO LIMING
RESUMO A calagem é benéfica para as plantas por promover a elevação do pH, neutralização do alumínio tóxico, aumentar o fornecimento de cálcio (Ca²+) e magnésio (Mg²+) e propiciar maior sistema radicular. No entanto, sabe-se que as espécies, principalmente nativas do Cerrado, respondem de formas distintas a essa técnica. Diante do exposto, o ob
