Using sensitive and selective immunological assays we have shown that in germinating caryopses of Hordeum vulgare L. cv. Himalaya, the level of gibberellin A4 (GA4) rises approximately 18-to 20-fold shortly (2–4 h) before α-amylase activity increases. Gibberellin A4 is the predominant immunoreactive gibberelin during these developmental stages and reaches a peak amount of approximately 9 pmol per caryopsis about 48 h after imbibition. Isolated aleurone layers produce GA4 in the presence of an… CONTINUE READING
