                         of climatic and phenological information in order to support 
                         strategic planning and sustainable management of this palm species 
                         native to the Amazon basin. The objective of this work was to 
                         evaluate agrometeorological conditions associated to phenological 
                         responses of tucuma as a species that has high economic potential 
                         for fruit pulp production. Meteorological data were collected 
                         during the period in which data were also collected for the 
                         phenology of the germplasm bank. Sensors were installed to monitor 
                         temperature and air relative humidity to where they are observed 
                         as phenophases. Analyses were conducted to identify the responses 
                         of the tucuma stems in function of agrometeorological conditions 
                         of the study area. Precipitation, thermal amplitude, and 
                         insolation showed positive correlations principally with respect 
                         to the percent of stems with bracts, inflorescences, or with 
                         fertilized inflorescences. In the fruiting phenological phase 
                         precipitation and air relative humidity influenced the percentage 
                         of stems with fruit clusters that were immature and also ones with 
                         mature clusters. High maximum temperatures compromise the 
                         expression of the percentage of stems with green fruit clusters. 
                         The tucuma stems were photosynthesizing and carrying out metabolic 
                         processes at a very high rate during the study period based on the 
                         high Normalized Difference Vegetation Index which was superior to 
                         0.41 during the three years of this study. The tucuma phenological 
                         phases, demonstrating a strong positive association with 
                         insolation, maximum temperature and thermal amplitude. RESUMO: As 
                         palmeiras est{\~a}o entre as esp{\'e}cies hiperdominantes na 
                         Amaz{\^o}nia e o tucum{\~a} (Astrocaryum vulgare Mart.) demanda 
                         de informa{\c{c}}{\~o}es clim{\'a}ticas e fenol{\'o}gicas para 
                         subsidiar o planejamento estrat{\'e}gico e o manejo 
                         sustent{\'a}vel dessa palmacea nativa da regi{\~a}o. O objetivo 
                         neste trabalho foi avaliar as condi{\c{c}}{\~o}es 
                         agrometeorol{\'o}gicas associadas {\`a}s respostas 
                         fenol{\'o}gicas do tucum{\~a} por ser uma esp{\'e}cie que 
                         apresenta alto potencial econ{\^o}mico na produ{\c{c}}{\~a}o de 
                         polpa dos frutos. Foram levantados dados meteorol{\'o}gicos 
                         correspondentes ao per{\'{\i}}odo em que foram realizadas as 
                         coletas de dados de fenologia no Banco de Germoplasma. 
                         Tamb{\'e}m, foram instalados sensores para monitorar a 
                         temperatura e a umidade relativa do ar onde eram observadas as 
                         fenofases. Foram realizadas an{\'a}lises para identificar 
                         respostas dos tucumanzeiros em fun{\c{c}}{\~a}o das 
                         condi{\c{c}}{\~o}es agrometeorol{\'o}gicas na {\'a}rea de 
                         estudo. A precipita{\c{c}}{\~a}o pluvial, amplitude t{\'e}rmica 
                         e insola{\c{c}}{\~a}o apresentaram correla{\c{c}}{\~o}es 
                         positivas principalmente quanto aos percentuais de

                         infloresc{\^e}ncias e de indiv{\'{\i}}duos com 
                         infloresc{\^e}ncias fecundadas. Nas fenofases de 
                         frutifica{\c{c}}{\~a}o a precipita{\c{c}}{\~a}o pluvial e a 
                         umidade relativa do ar influenciaram nos percentuais de 
                         indiv{\'{\i}}duos com cachos de frutos imaturos e de 
                         indiv{\'{\i}}duos com cachos de frutos maduros. Temperaturas 
                         m{\'a}ximas elevadas comprometem a express{\~a}o da porcentagem 
                         de indiv{\'{\i}}duos com cachos verdes do tucum{\~a}. Os 
                         tucumanzeiros estavam em plena capacidade vegetativa durante as 
                         avalia{\c{c}}{\~o}es a campo, pois o NDVI manteve-se, 
                         dominantemente superior a 0,41 nos tr{\^e}s anos analisados. As 
                         fenofases do tucum{\~a} demonstrando forte associa{\c{c}}{\~a}o 
                         positiva com insola{\c{c}}{\~a}o, temperatura m{\'a}xima e
