Different Extents of Salt Stress in Epipremnum aureum as Influenced by Uniconazole and GA3

Abstract
|

|
|
Effects of uniconazole and GA₃ on the salt stress of pothos (Epipremnum aureum) and golden pothos (E. aureum ´Lime´) were tested. Number of defoliated leaves increased with uniconazole than either with or without GA₃ in the saline condition. It, however, became less than with or without GA₃ in the later days. NaCl reduced the cell diameter of young leaf, whereas the degree of reduction was less with uniconazole than either with or without GA₃. Water potential in the saline condition increased with uniconazole. Uniconazole increased photosynthetic rate of pothos, but GA₃ reduced that of golden pothos. Transpiration of pothos increased with uniconazole. Uniconazole reduced ethylene production of two cultivars examined.
