|a Intact, light-grown pea (Pisum sativum L. cv. Alaska) seedlings were subjected to continuous horizontal gravistimulation and their growth and bending response compared with seedlings whose shoot tip and youngest leaf had been excised and with seedlings to which a counterweight to replace the mass of the decapitated tissue was added. While all seedlings achieved vertical orientation in 2 to 3 h, seedlings that were counterweighted bent upward at a significantly slower rate than the non-counterweighted, decapitated plants. In addition to this effect of mass on the rate of bending, decapitation also removed a major supply of auxin to cells in the bending zone which resulted in the slower bending of treated plants. Thus when using decapitation both the loss of mass and the time course of the response must be considered to understand its effect on gravitropism
