Analysis of the effects of DIF for the flower setting habit of the tomato in greenhouse

Currently, Changes in crop yields and in a monthly reduction of crop yields due to the occurrence of defective flower setting and among abnormal flower cluster from disturbance of flowers setting habit in greenhouse. In this study, we went to the measurement of biological information of the plant in order to create a database for diagnostics and environmental control growth based on the Speaking Plant Approach. As a result, Disturbance of flower setting habit of tomato was demonstrated in the following tomato DIF4. DIF of he for suitable cultivation in tomato is DIF5 ~ 7. But, Likely to affect of from DIF7 onward in flower setting habit of tomato is low. The strength of the DIF and cultivation stage is not relevant to tomato. And, DIF will delay flower differentiation.
