Fig. 3From: What role does the seed coat play during symbiotic seed germination in orchids: an experimental approach with Dendrobium officinaleEffects on seedling development from seeds pretreated with 1% (w/v) NaClO for 5, 10, 20, 30 and 40 min under two compatible fungi (TPYD-2 and PI) treatments. The significant differences among seed pretreatment durations in the two fungal treatments are shown by different lowercase letters at p < 0.05Back to article page
