Title: Flowering, Spur Formation and Limb Angles of Delicious Apple Strains
Author: D.O. Ketchie
Number of spurs per meter of limb, number of flowering spurs per spur and limb angles were counted or measured on 17 strains of Delicious apple (Malus domestica Borkh.) for 5 years.

There was no difference in the width of the limb angles among strains.
