Effect of cotyledons and epicotyl upon the activity of endogenous gibberellins in roots of flax (Linum usitatissimum L.) seedlings

Effect of cotyledons and epicotyl upon the activity of endogenous gibberellins in roots of flax (Linum usitatissimum L.) seedlings

In 11-day-old flax seedlings, the level of endogenous gibberellins in roots decreased within 12 hours after the excision of cotyledons and the epicotyl; however, 24 to 48 hours after excision the gibberellin level increased again. The decrease in the gibberellin level within the first 12 hours after...
