Cotyledons are a major source of inherent root promotion in mung bean cuttings. Cuttings from seeds of different size and seedlings of different ages gave a variable rooting response in bioassays for root-promoting activity. A consistent and sensitive bioassay was achieved by removing the cotyledons from germinating seedlings 4 days after sowing.
