Summary
Ten-week-old pepper plants (Capsicum annuum L. `Bell Boy`) were grown at 5 different root-zone temperatures (RZT) (12, 18, 24, 30, or 36 +- 2 C) for a period of 8 weeks. Maximum shoot dry weight and leaf area were measured at 24 and 30 RZT. Leaf area ratio (LAR) was not significantly affected by RZT treatments. Fruit weight was maximum at 30 RZT, but earliness was delayed at high RZT. Nitrogen, P, and K content of shoots were increased, but Mg and Ca concentrations were reduced at high RZT. Plant photosynthesis was the highest at 36 RZT. Increasing RZT improved both greenhouse or outdoor pepper production. [AS]
