Qualitative and quantitative analyses of gibberellins throughout seed maturation in Pisum sativum cv. Progress No. 9

Abstract

In addition to the previously identified GA₂₀ and GA₂₉ in immature seeds of Pisum sativum L. cv. Progress No. 9, GA₉, GA₁₇, GA₃₈, GA₄₄, abscisic acid and dihydrophaseic acid have been identified. The levels of GA₉, GA₁₇, GA₂₀ and GA₂₉ have been determined throughout seed maturation by GC-MS. GA₂₀ and GA₂₉ are the major gibberellins in terms of quantity, the other gibberellins remain at very low levels throughout development of the seed.
