Setaria lutescens

Numerous laboratory studies of the response of plants of both types to a change in the quantity CA (Bazzaz, 1986) testify to the wide range of quantitative estimates of photosynthesis variations for the C3 type. On average, plants respond to a change in C02 concentration after a 1-month delay. Doubled C02 concentration causes a doubling of the rate of photosynthesis. Further increase of CA up to 400% leads to the effect of photosynthesis saturation for some plants (i.e., there can be a 20% addition to the rate of photosynthesis), and in some cases (e.g., Setaria lutescens) photosynthesis is suppressed. In fact, plants of the C4 type even with the present quantity of CA are in a state of photosynthesis saturation. 

Perloline was found in only the four following species out of eighty-five Gramineae, Cyperaceae, and Juncaceae that were examined L. temulentum, L. muUiflorum Lam., Festuca elatior L. (F. arundinaceae Schreb.), and Setaria lutescens (Weigel) Hubb.
