Physiological Quality of Badea Seeds (Passiflora quadrangularis L.) with and Without Storingon Different Substrates

ABSTRACT

Badea is known for the size and shape of the fruit, or as giant passion fruit. The propagation of passifloraceas is mainly done by means of seeds. Seed conservation is one of the main steps in seedling production that makes it possible to guarantee the maximum quality of theseed for a given period oftime and can be done through refrigeration.The experiment was conducted in the greenhouse of the Federal Institute of Education, Science and Technology of Tocantins, city of Gurupi/TO, from March 17 to August 10, 2020. After fruit harvesting, pulping was performed using running water and light friction in the nylon sieve with sand to facilitate the separation of the seed and pulp. Then the seeds were placed on a paper towel for 24hours, partly storedin the refrigerator for 10 days, and another part is sownimmediately. The seeds of passion fruit melon, without storage, sowed in the commercial substrate, showed greater viability and vigor.
