Abstract
|
|
|
The changes in morphological adaptations of tomato plants between aeroponics and nutrient film technique (NFT) were investigated in order to clarify the characteristics of two different hydroponic systems.
The root development judged by the amount of root hairs and the diameter of secondary roots was better in the aeroponics than in the NFT. The anatomical observation also indicated that root cap, epidermis and cortical layer were thicker, and number of cell layers in the cortex was more, and the zone of cell division was longer in the roots grown in the aeroponics than those grown in the NFT.
Also, the intercellular space in the roots grown in the aeroponics were larger than those grown in the NFT.
