1. 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

2. Allometric models for estimating the leaf area of lisianthus (Eustoma grandiflorum) using a non-destructive method
ABSTRACT Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in the post-harvest. The leaf area measurement is fundamental in plants because the leaves are directly related to several processes such as transpiration, radiation interception and CO2 fixation that enable the plant to grow. The objective of t

3. Gas exchange and water stress index in soybean cultivated under water deficit and soil compaction
ABSTRACT Water stress is intrinsically related to soil water availability which is determinant in gas exchanges, as well as soil compaction in soybean growth and development. This study aimed to evaluate the leaf gas exchange, water stress index, and dry mass accumulation of soybean cultivated in different daily irrigation depths and bulk density. The treatm

4. 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

5. COVID-19 should be a methylene blue “promoter”
ABSTRACT When determining plant transpiration (TR) using the thermal dissipation probe method, it is necessary to calibrate the sap flow (SF) estimation equation for each species under study, and thus obtain reliable information about the water demand of crops. This study aims to calibrate the equation used to determine SF using the thermal dissipation probe

7. 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

8. 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

9. 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

10. Gas exchanges and growth of passion fruit seedlings under salt stress and hydrogen peroxide1
RESUMO A região semiárida do Nordeste brasileiro apresenta condições edafoclimáticas adequadas à produção do maracujazeiro, mas a água utilizada na irrigação, comumente, possui altas concentrações de sais, que são prejudiciais ao crescimento e desenvolvimento das plantas. O fornecimento prévio de peróxido de hidrogênio induz a aclimatação

12. LEAF TEMPERATURE AND TRANSPIRATION OF PEQUI TREES WITH AND WITHOUT WATER RESTRICTION
ABSTRACT The answers to when and how much to irrigate orchards can be obtained based on the measurements of plants' transpiration and leaf temperature. This study aims to determine the leaf temperature and sap flow of the pequi tree (Caryocar brasiliense Camb.), both with and without water restriction. Further, the leaf temperature was measured by infrared t
