Seed germination and germination index immediately following polymer coating and seed dressing with pesticides were not significantly (P≤0.05) different in the laboratory and greenhouse as compared to the polymer alone and non-treated seed treatments. Seed germination in the greenhouse assay was slightly higher than in the laboratory. Cucumber germination varied from 84.0 to 95% under laboratory conditions, whereas germination in the greenhouse varied from 92 to 97% (Table 1). The mean percent germination from laboratory and greenhouse tests were 89 and 93%, respectively, and germination index was 13, ranging from 13 to 14 (Table 1).
