抄録

Endogenous GAs in the immature seed of maize (hybrid Ko-No. 7) were analyzed, and GA₁ GA4, GA₈, GA₉, GA₁₇, GA₁₉, GA₂₀, GA₂₉, GA₃₄, GA₄₄ and GA₅₃ were identified by GC/MS and/or GC/SIM. Among these GAs, GA₂₀ was the major one.
Endogenous GA₁, GA₃ and GA₄ in the tassel, cob and silk of maize were analyzed, and gave information that suggests a role for GAs in the reproductive organs of maize.
