Total yields of vine tip of seven varieties of Leaf-vegetable sweetpotato during 2006-2007 were investigated; proportions of the weights of leaf, leaf stalk and stem in total vine tip yield and their changes among varieties and during topping stages were studied. The results showed that vine tip yields of sweetpotato were significantly different among either varieties or topping stages; leaf yield accounted for about 51% of total vine yield, and changes in leaf yield among topping stages were higher than that among varieties; while yields of leaf stalk and stem each accounted for 25% of total vine tip yield, their changes among varieties were higher than those among topping stages. These results revealed the yield composition of vine tip of Leaf-vegetable sweetpotato, which provided scientific references for breeding and cultivating new Leaf-vegetable sweetpotato variety and its industrialization.
