Witches' broom disease of Theobroma cacao in Brazil. I. Inoculation of ungerminated seeds. In: Theobroma v. 13 p. 47-49, 1983.

Abstract

Ungerminaled seeds of cacao infiltrated under vacuum wilh spore suspension of Crinipellis perniciosa (Stahel) Singer and then pre-germinated before planting produced hypertrophied hypocotyls and developed hypertrophied axillary buds. This technique of inoculation could be useful in mass-screening of individual plants for their reaction to infection by C. perniciosa.
