Abstract

The present study aimed to investigate the influence of different substrates, temperatures and storage conditions on shepherd's purse seed quality. It was evaluated in germination paper substrates Germitest®, vermiculite, sand and Plantmax®, and roller temperatures of 25, 30, 15-25 and 20-30°C. Longevity was measured by the temporal response to different packaging (paper, plastic and aluminum) and storage environments (laboratory and freezer). Germination percentage, germination rate index, percentage of normal, abnormal and dead seedlings were evaluated. The paper roll at 25°C provides an optimal condition for maximum germination potential and vigor. The storage for three months in freezer provides an increase in vigor in the seed without storing. The laboratory promoted reduction in germination potential from nine months of storage, with total loss of germination at 24 months. The combination of freezer and plastic packaging provide maintenance of seed longevity after two years of preparation.

Key words: Germination, vigor, longevity.
