Tuber of most varieties of white Guinea yam, Dioscorea rotundata Poir., produce a single sprout in the proximal region after the break dormancy. The location and pattern of sprout formation on intact tubers of a multiple sprouting variety, Pepa were studied. Only 0.4% of the tubers had a single s...
