Brasil. O objetivo deste trabalho foi estimar os coeficientes de herdabilidade e repetibilidade das
variáveis agrotecnológicas e predizer os ganhos genéticos de uma população de melhoramento de cajuí da
Embrapa Meio Norte. Os dados das variáveis estudadas de cada safra foram avaliados no programa Selegen-
REML/BLUP. A ordem das variáveis analisadas foi: V1: peso do fruto (PF, em g), V2: peso do pedúnculo
(PP, em g), V3: peso da castanha (PC, em g), V4: diâmetro basal (DB, em cm), V5: diâmetro apical (DA,
em cm), V6: comprimento do fruto (CP, em cm), V7: firmeza do endosperma (FIRMEZA, em N), V8: teor de
vitamina C (VitC, em mg/100g), V9: teor de sólidos solúveis totais (SST, em %), V10: pH do endosperma (pH),
V11: acidez total titulável (ATT, em %) e V12: relação STT/ATT (adimensional). O peso do fruto e teor de
vitamina C podem ter seus valores preditos a partir do diâmetro basal e/ou comprimento do pedúnculo cujas
medidas são de fácil mensuração. As medianas e altas estimativas dos coeficientes de herdabilidade e repetibilidade
possibilitaram selecionar precocemente um dos genótipos, 4, com acurácia a partir de duas medições (anos).
O genótipo 4 apresentou as maiores médias para os atributos físicos e tecnológicos do fruto, podendo ser considerado
candidato à seleção para reprodução assexuada no cultivo com objetivo duplo (consumo in natura e industrializado). |

This study aimed to assess the effect of thermal-hydraulic variables in female buffaloes with or without direct solar exposure in a year of strong El Niño through behavior responses and infrared thermography to reinforce the environmental comfort indicators, in Marajó Island, Pará, Brazil. The experiment was carried out in Cachoeira do Arari municipality and 20 female Murrah buffaloes were randomly assigned to two groups: Group WS (n = 10) was kept in pickets with native trees. Group NS (n = 10) was kept in crush squeeze with no shade. Data on air temperature (AT, °C), relative air humidity (RH, %), wind velocity (WV, m/s), rectal temperature (RT), respiratory rate (RR), and body surface temperature (BST) were collected. Practical Buffalo Comfort Climatic Condition Index (BCCCI), practical Buffalo Environmental Comfort Index (BECI), Temperature and Humidity Index (THI) and Benezra's Thermal Comfort Index (BTCI) were obtained. Infrared thermography analysis was carried out with a FLIR T-series T640bx camera. Data on time spent grazing, ruminating, idleness, and in other activities were recorded. A significant difference in AT of ~1°C was found between the groups at 6 a.m., 10 a.m. and 6 p.m. THI indicated emergency conditions. Female buffaloes were at danger PBCCCI conditions at 2 p.m. There was also significant difference for RT between treatments at 10 a.m., 2 p.m. and 6 p.m., whose values were higher (P < 0.05) for animals from NS Group, with the highest mean time at 2 p.m. Pearson correlation was significant and positive (P < 0.01) between RT mean and VUL, TI and ORB mean, maximum and minimum temperatures. The total time given to grazing was 518.2 min for the group NS and 629.5 min for the group WS. Rumination was more pronounced in the afternoon shift for the group NS. Buffaloes kept in a system with trees graze, ruminate and perform other activities with more intensity than animals raised in systems without access to shade, and tend to hyperthermia, mainly at 10 a.m. and 2 p.m., in Marajó Island, Pará, Brazil.
