Abstract

SECTION I: 1. Well-developed root systems of field pea (Pisum arvense L.) var. New Zealand Maple, have been obtained from excised tips 0.5 cm. in length grown under sterile conditions in the nutrient solution of Bonner and Devirian (1939). 2. This solution is unsuitable for the growth of excised root tips of sweet pea, sea pea, Soya bean and black wax bean, but allows a certain limited growth of tips of a dwarf variety of broad bean. 3. The temperature best suited to the maintenance of healthy excised root systems of pea is in the region of 15-16
