Abstract
THE present investigation was to determine whether the effect of gibberellic acid in causing chlorosis was due to an interference in chlorophyll formation or to some secondary effect1. Pisum sativum var. Meteor were grown in the field in a block arrangement, and alternate rows were treated with gibberellic acid (Y.F. 4961, Plant Protection, Ltd.). Gibberellic acid diluted to 100 p.p.m. with water was sprayed on the upper surface of the plant 10 days after emergence.
