Table 7 Results from partial regression analysis among potassium uptake (KU) by flowers and K content at different plant parts of Zygopetalum maculatum orchids.

From: Potassium application enhances vegetative and reproductive yield of Zygopetalum maculatum and reduces post-flowering K depletion from storage organs of the orchid
