Effect of Ringing Cotton Stems on Content of Reducing Sugars and Insoluble Nitrogen and on Degree of Infection with Xanthomonas malvacearum (E.F.S.) Dowson

Nature volume 190, pages 934–935 (1961)Cite this article

Abstract

Hughes and Fowler1 reported that the glucose-level of the leaves of synthesized varieties containing black-arm resistance genes B 2 or B 2 + B 3 was higher than that of the susceptible parent type during the first three months after sowing. Bird and Joham2 found that girdling the main stem of a susceptible variety caused cotton plants to become more resistant to the same disease. In the present investigation the effect of ringing the main stem of cotton plants on the level of reducing sugars and insoluble nitrogen in the leaves, and its relation to infection with the angular leaf spot disease, were examined.
