In order to determine the most appropriate nutrient solution spraying interval and effects of light quality in the root zone on anthurium in aeroponic system, a split plot experiment, with completely randomized design, was carried out in a greenhouse located in the city of Karaj, Iran. In this study, time between the sprays was the main plot and consisted of two levels (2 minutes spray and 30 m...

Subsequent chromatographic ...
