Effect of Aeroponics on the Growth, Yield and Quality of Tomato Plant

The aim of this research was to evaluate the growth,yield and quality of tomato plant in an aeroponics system.Areoponics(AC) and soil culture(CK) were compared in spring production(2005) with the Shanqi recipe of tomato nutrient solution.The results showed that there was an increase in the plant height,and average fruit weight per cluster and single plant yield,in addition,there was an increase in the content of chlorophyll and net photosynthesis rate,however there was not significant change in the stem wide and average fruit number per plant,compared with the soil culture(CK).Besides,there was a decrease in the content of VC,soluble sugar and organic acid,and the sugar-acid rate.The results indicted that aeroponics may increase the photosynthesis and the carbohydrate transportation with a result of high yield,but may not increase the fruit quality.
