Anatomic effects of barley yellow dwarf virus and maleic hydrazide on certain Gramineae

Hilgardia, 1957, vol. 27, issue 1

Abstract: Infection with the virus of barley yellow dwarf disease and treatment with maleic hydrazide produce many similar external and internal degenerative changes. These are depression of growth, the yellowing of leaves, the forming of sugary exudate on leaves, and the necrosis of certain tissues, particularly of the phloem.
