Abstract
Organic acids, sugars, and amino acids were determined chromatographically in Thatcher spring wheat grown under short and long nights. There was a marked decrease in organic acids and a simultaneously large increase in sugars of 46-day-old Cu-sufficient plants. Distribution of C14 from C14O2 increased in accordance with the above products formed. Cu-deficient plants did not show these changes. Cu-sufficient plants accumulated less asparagine and aspartic acid than Cu-deficient plants and comparably contained the same, but lesser quantities of other amino acids. The effects of Cu on these end-products of metabolism are illustrated and discussed with reference to other changes which occur in Cu-deficient wheat. The changed sugar and organic acid metabolism was not directly related to head development.This publication has 5 references indexed in Scilit:
