Use of Seeds in the Insect Transmission of Some Plant Viruses

Abstract

THE methods previously adopted for the insect transmission of the viruses causing swollen-shoot disease of cacao (Theobroma cacao L.) employed seedlings usually between six and twelve months old. An improved technique utilizes the seed as a test plant and a watch-glass or specimen tube as a cage, a method which might be applicable to experiments with viruses of other plants with exalbuminous seeds.
