Temperature of germination, desiccation sensitivity and storage of jackfruit seeds

Abstract

To evaluate the effect of temperature in germination and the behavior germination of jackfruit seeds related to desiccation and storage, freshly seeds (56% HR – sample1) and dried seeds in the shade in ambient temperature were used. They stayed there for 7 days until the attainment of 29% of humidity (sample 2).The seeds of both samples were wrapped in sheets of paper, involved in polyethylene bags and stored in cold chamber (10 °C, 40% HR). Before the storage and during the 30 and 60 days of storage, seeds were evaluated for germination test in trays with sand substratum, in BOD incubator at 25 °C and 35 °C. It was observed that the temperature of 25 °C is appropriate for the germination of jackfruit seeds. These seeds don’t tolerate desiccation at 29% humidity, their germination is gradually reduced during the storage, and it is null during the 60 days.
