SUMMARY A medium of sucrose and inorganic salts permits development of isolated embryonic axes of hazel into leafy seedlings. Gibberellic acid stimulates the early growth of excised axes in this medium and with sucrose alone. In the longer term, GA 3 leads to less root growth, increased shoot growth (but an overall reduction in seedling length) and a poor leaf development. Abscisic acid markedly inhibits extension of isolated axes irrespective of the presence of gibberellic acid.
