Resumo: The present research had as objective to evaluate the influence of raceme and fruit position on physiological quality of castor bean seeds (Ricinus communis L.) during storage of cultivar AL Guarany 2002.  The treatments were: position of the raceme in plants (primary, secondary and tertiary) and position of fruit in racemes (low, medium and high). After fruit extraction, seeds were stored under environmental conditions for twelve months. The experimental design used was the completely randomized in a split-plot arrangement. Main plots consisted of the interaction raceme x fruit position and subplots were the storage time. Physiological quality was evaluated quarterly through tests of moisture content, germination and vigor (first count, accelerated aging, seedling length and seedling dry matter). Neither the position of racemes in the plant nor fruit in racemes does not affect germination of castor bean seeds. Dormancy of castor bean seeds decreases during storage, but also increases percentage of abnormal seedlings, seedling dry matter and root, hypocotyl and seedling total length.

O trabalho teve por objetivo determinar a influência da posição do racemo na planta, do fruto no racemo e do armazenamento na qualidade fisiológica de sementes de mamona (Ricinus communis L.) da cultivar AL Guarany 2002. Os tratamentos foram: posição do racemo na planta (primário, secundário e terciário) e posição dos frutos no racemo (inferior, médio e superior). Depois da extração dos frutos, as sementes foram armazenadas em condições ambientais para avaliações trimestrais de qualidade fisiológica até os doze meses. O delineamento experimental utilizado foi o inteiramente casualizado com parcelas subdivididas. Na parcela foi estudado o fatorial e nas subparcelas os tempos de armazenamento. Foram determinados no momento da colheita e aos três, seis, nove e doze meses o grau de umidade das sementes, a germinação e o vigor (primeira contagem do teste de germinação, envelhecimento acelerado, crescimento e massa de matéria seca de plântulas). A posição do racemo e dos frutos no racemo em mamoneira não influencia a porcentagem de germinação de sementes de mamoneira. Com o decorrer do armazenamento a dormência das sementes diminui e aumenta a porcentagem de plântulas anormais, a massa de matéria seca, o comprimento total, de raiz e de hipocótilo das plântulas.
