Germination of cannabis seeds in 1% hydrogen peroxide solution and water. (a) Comparison of germination percentage between 1% H₂O₂ and water. Data were shown as mean ± SE (n = 3). (b) Representative photographs of germinated seeds/seedlings in the 1% H₂O₂ or water on 4^th day. (c) Various stages of germination for cannabis seedlings in 1% H₂O₂ solution. 12–24 h, cannabis embryo absorbs water until radicle breaks through the seed coat; 24–48 h, further development of radicle; 48–96 h, cotyledons emergence and development of two fully opened cotyledons with two early true leaves.
