Abstract
Seed from peanut pods exhibiting microscopic shell damage, damage detected only with a staining technique, was as susceptible to colonization by Aspergillus flavus as seed from pod with visible shell damage. The isolation frequency of A..flavus from seed from pods with microscopic and visible damage was 36.8 p. 100 and 42.8 p. 100 greater, respectively, than from seed from nondamaged pods. The rate of colonization of seed from pods treated with A. flavus and nontreated pods over a 180 hour incubation period was similar for both damage types. The rate of colonization of seed from nontreated nondamaged pods with a moisture content of 10 p. 100 was less than the rate of colonization of seed from pods with microscopic and visible damage. Also. the colonization process of seed from nondamaged pods lagged about 90 hours behind the colonization of seed from pods with microscopic and visible damage. Similar results were obtained with pods with a moisturc content of 30 p. l00 seed from with from pods with 50 p. 100. moisture content were colonized much less frequently by A. falvus than seed from pods with moisture contents of 10 and 30 p. 100. The isolation frequency of A. falvus between seeds from pods with microscopic and visible damage became even less evident with time of incubation. A Gompertz curve was used to establish a mathematical model to determine the probable relationship between pod damage, isolation frequency and time of incubation
