These include the food crops maizesugar canemilletand sorghum.


Branches, when they occur, are borne in whorls at the node, as are the scale leaves. Environmental stress such as nutrient or moisture deficiencies may lengthen the time between vegetative stages but shorten the time between reproductive states.
