The atomized nutrient solution droplet sizes and spraying intervals can impact the chemical properties of the nutrient solution, biomass yield, root-to-shoot ratio and nutrient uptake of aeroponically cultivated plants. In this study, four different nozzles having droplet sizes N1 = 11.24, N2 = 26.35, N3 = 17.38 and N4 = 4.89 µm were selected and misted at three nutrient solution spraying intervals of 30, 45 and 60 min, with a 5 min spraying time. The measured parameters were power of hydrogen (pH) and electrical conductivity (EC) values of the nutrient solution, shoot and root growth, ratio of roots to shoots (fresh and dry), biomass yield and nutrient uptake. The results indicated that the N1 presented significantly lower changes in chemical properties than those of N2, N3 and N4, resulting in stable lateral root growth and increased biomass yield. Also, the root-to-shoot ratio significantly increased with increasing spraying interval using N1 and N4 nozzles. The N1 nozzle also revealed a significant effect on the phosphorous, potassium and magnesium uptake by the plants misted at proposed nutrient solution spraying intervals. However, the ultrasonic nozzle showed a nonsignificant effect on all measured parameters with respect to spraying intervals. In the last, this research experiment validates the applicability of air-assisted nozzle (N1) misting at a 30-min spraying interval and 5 min of spraying time for the cultivation of butter-head lettuce in aeroponic systems.

Abstract Transplanting stress is: (1) a temporary condition of distress from injuries, depletion, and impaired functions; (2) a process of recovery; and (3) a period of adjustment to a new environment. Some transplanting stress is unavoidable, even with good stock in a favorable environment. The degree and duration of stress depend on the interactions of seedling performance potential and the site environment. Renewal of root-to-soil contact is important for resumption of adequate water and nutrient uptake. Root growth is sensitive to soil temperature and plant moisture stress. If reserve carbohydrates are exhausted before they are replenished from photosynthesis, the seedlings may die. Preplant handling and postplant drought aggravate transplanting stress. Stress can be minimized by planting stock with high stress resistance, preserving seedling performance potential, preparing a favorable planting site environment, and planting the seedlings properly.
