Untersuchungen über den Einfluß von Gibberellinsäurespritzungen auf den Ertrag, die Anatomie der Wurzel und die Karotinverteilung bei Karotten

摘要

Investigations on the Influence of Gibberellic Acid Treatments on Yield, Root Anatomy and Carotene Distribution of Carrot Plants.Application of GA3onto the shoots of carrot plants increases shoot growth whereas root growth was reduced. Furthermore, due to the GA3‐application carotene content (Table 2) in the shoots was increased and decreased in the roots. Anatomical investigations of the roots revealed that apparently the reduction of root growth after GA3‐application was due to a decrease of phloem oriented cambial activity (Table
