The Contribution by Leaves of Different Age to New Growth of Subterranean Clover Plants Following the Removal of a Sulphur Stress II. Uptake and Distribution of Sulphur

Abstract

Plants were grown in three sulphur pretreatment solutions (0'25, 1, and 4 p.p.m.: S1. S2, and Sa) and transferred to full solutions (= Sa) 32 days after sowing. On the same day the five oldest trifoliate leaves were shaded in one-third of the plants, in another third these leaves were removed and the remainder of the plants were left untreated (controls).
