Research areas

Kniep mainly worked on plant physiology on chemotaxis , photosynthesis and nutrition of marine plants and on the sexuality of lower plants.

Among other things, his work on the cytology and genetics of fungi , especially the Basidiomycetes , is significant . Among other things, he investigated the development of the pair nucleus stages in the Hymenomycetes and the conditions for buckling in the Basidiomycetes.

From 1916 he was editor of the journal for botany.
