Abstract
Gibberellin pretreatment of hazel seeds induced significant increases in the incorporation of carbon-14 from [2-14C] acetate into both glutamate and sucrose, while the amounts of radioactivity incorporated into citrate, malate and succinate were significantly higher after pretreatment with sterile water. A ratio based on the relative amounts of carbon-14 incorporated into glutamate and into the TCA cycle acids indicates that gibberellin treatment causes a diversion of metabolites from the essentially respiratory TCA cycle into synthetic sequences such as glutamate formation. Gibberellin treatment also appears to stimulate the activity of a reversed glycolytic sequence, resulting in the production of sucrose.Keywords
