Description: This research determined physiological maturity indicators in Tabebuia impetiginosa seeds. In the period of August 6th until October 6th,  eight  collections  were  made in trees located in the Federal University of Lavras – UFLA,  Minas Gerais State and in its surroundings. After collections, water content, dry matter, fruits and seeds color; percentage of radicle emission;  normal  and  abnormal seedlings;  deteriorated  seeds  and  germination  index (GI) were determined.  The results obtained showed  that  when  the  fruits  started the dehiscence they present green color with purple points.  The  seeds  showed  green-brownish-yellow color.  At this point, the water content in the fruit and in the seeds  was  69.02%  and  50.98%,  respectively. The fruit and seeds dry matter were, respectively, 30.98g/100g  and 49.02g/100g  of  fresh  matter. The percentage of radicle emission was 73%; normal seedlings 53%, abnormal seedlings 20%; deteriorated seeds 27%; and GI 2.29%.  The  presence of cracks  and  green  spots  with  purple points in the fruits and green-brownish-yellow color in the seeds are good practical indicators to determine the time of harvesting Tabebuia impetiginosa seeds.
