Abstract
The comparative effect of 2,4-D, IAA, IBA, and NAA on the metabolism of p32 in bean plants was investigated. 2,4-D treatment greatly reduced the upward movement of P32 to the leaf; the degree of reduction was proportioned to the amount of 2,4-D applied. Treatment with growth regulators modified the distribution and accumulation pattern of p32 in bean plants. The incorporation of P32 into some P intermediate compounds in the water soluble fraction was affected by plant growth regulator treatment The greatest effect was observed in 2,4-D treated plants.
