The pigeon pea appears as a good option for farmers to be used directly in food and/or green manure. In spite of this potential, its cultivation area in our conditions is still incipient, mostly due to the lack of seeds of superior quality. It is know that the process of physiological deterioration of seeds varies according to species, constituting a relevant factor in seed technology. Storage problems in Brazil are still an issue and the decrease of physiological quality of seeds at this stage is considerable, especially for seeds containing high concentration of protein ( 22%) as for the pigeon pea. In this context,this study aimed to evaluate the physiological deterioration of pigeon pea seeds stored in different containers and environments for 10 months. The completely randomized design in a factoral 2x4x6 with four replication was used. The treatments were constituted of two stage environments(natural condition of laboratory (25+ 2C) and refrigerator (4+2C), combined with four types of packaging(PET) bottle, plastic bag, burlap bag and kraft paper) and six storage periods(0,2,4,6,8,10 months). The physiological seed quality was determined in a timeframe of two months by the following tests: Standard Test Germination - TPG, TPG first count, accelerated aging and electrical conductivity. It is concluded that the percentage of normal germination seedlings by TPG decrease linearly along the storage period; the PET bottle and Plastic bag preserved the vigor and viability of the seeds more efficiently along the storage, being that the PET bottle far being waterproof and tightly sealed has obtained better performance; and the refrigerator-controlled environment is the most suitble for storage of the pigeon pea among the tested environments
