The chlorophyll deficiency in citrus seedlings known as albinism was induced by inoculating seed with certain clones of Alternaria tenuis, or by germination of the seed in contact with extracts from the fungus. The active material in the extracts apparently has a rather specific inhibiting effect on chlorophyll formation in seedlings of various species.
