Topping influences crop photosynthesis and alters the absorption and redistribution of nutrients: a case study of tobacco [PDF]
Frontiers in Plant ScienceTopping eliminates apical dominance in tobacco, enhancing the quality of the upper leaves. However, the mechanisms by which topping influences photosynthesis and the leaf structure, and regulation of chemical composition remain unclear.
