Influence of length of the illumination period on root formation in cassava, Manihot utilissima Pohl.

Abstract

Sprouted cuttings of 6 cassava cultivars were subjected to light periods of: 10 h daylight, 10 h daylight plus 2 h weak light, 10 h daylight plus 4 h weak light and 10 h daylight plus 6 h weak artificial light, respectively, to study root formation under these conditions. The optimal light period was about 12 h; longer light periods inhibited root formation. Cassava was considered to be a short-day plant.-A.G.G.H.
