Gibberellins A(1) and A(34) (possibly A(2)) were found as products of metabolism of 1,2-[(3)H]GA(4) during germination of Pinus attenuata pollen. The conversion from GA(4) to GA(1) and GA(34) occurred as hydroxylations at atoms C-13 and C-2 of the ent-gibberellane skeleton, respectively. Percentage interconversion of the GA(4) absorbed was in the range of 0.15 to 0.43% for GA(1) and 1.54 to 3.22% for GA(34). Identifications were made on a gas-liquid chromatograph with radioactive monitoring by comparison with standards.
