Effect of earthworm casts on protein synthesis in radish (Raphanus sativum) and lettuce (Lactuga sativa) seedlings


The protein-synthesizing capacity of 3-day-old seedlings of radish and lettuce grown in the presence of earthworm casts was investigated using L-14-C-leucine incorporation. The results showed that earthworm casts increased protein synthesis by 24% for lettuce and 32% for radish, althought no significant differences in protein content were evident.
