Time course of root initiation and development in perennial ryegrass - a new perspective

Abstract

Perennial ryegrass (Lolium perenne) tillers of cultivar 'Alto' were grown in hydroponic culture in winter- spring and autumn experiments and roots of known age were individually dissected and a number of properties including dry weight, main axis length and total length were measured to define root developmental status at successive positions or phytomers on the tiller axis.
