Abstract Focusing on the extreme temperatures during winter and summer seasons，particularly
the higher mean temperature and lower humidity generated by cli mate warming，and the influence of this
microclimate change in greenhouse on growth and fruit quality of tomato，German scientists developed
a new climate strategy for greenhouses to avoid plant damages and reported their two year research. In
this context，the results are introduced and reviewed. The results showed that a combined application
of a high pressure fog system and CO2 enrichment can be applied to decrease the inside temperature
and to increase the levels of relative humidity and CO2 concentrations at a high ambient temperature，
accompanied by an increase in mean temperature. Such microclimate in the greenhouse were sufficient to
accelerate plant growth，to increase dry matter in leaves，and to promote the formation of fruit set per
truss in comparison to those grown under conventional climate conditions. Furthermore，the algorithm
of the new climate strategy led to a maximum total yield increase by 20%，to a reduction of blossomend
rot in tomatoes and to a pronounced increase in fruit size during the spring experiments. The climateconditions caused by the new technology significantly promoted secondary metabolism，resulting in a
maximum increase in contents of lycopene（ by 49%），β-carotene（ by 35%），and phenolic compounds
（by 16%） as well as associated antioxidant activity in the water-insolu ble（ by 18.5%） and water-soluble
（by 35.4%） fraction compared to the conventional treated plants．Therefore，the new climate strategy
may be appropriate to increase the total yield and to improve the fruit quality as well as the healthpromoting
properties of tomatoes.
