Abstract:
Exogenous hormones had been proved to be effective to prevent the problem of the abscission of flower and fruit of tomatoes in the environment of low temperature and weak light during winter cultivation.Two types of tomatoes including small-sized and big-sized were selected to conduct the experiment and four kinds of exogenous hormones configured by three different concentrations.Exogenous hormones were used to treat tomato flower on flowering stage to explore the effect on the fruit setting rate，deformity fruit and appearance quality.The experiment aimed to select more suitable exogenous hormone and appropriate concentration.The results showed the fruit setting rates of the third，the fourth，the fifth and the sixth fruit were overall higher when the concentration of PCPA was 15 mg?L-1 for small-sized tomato.While for big-sized tomato,there was no significant difference between the third and the fourth fruit（P<0.05）.On the whole，the fruit setting rate was higher than the others when sprayed with 20 mg?L-1 2,4-D and 15 mg?L-1 PCPA.When the concentration of PCPA and New Flower Fruit were 15 mg?L-1，the deformity fruit rates were zero.For big sized tomatoes，fruits′ vertical diameter and horizontal diameter were bigger than the others when sprayed with 15 mg?L-1 PCPA，meanwhile，the fruit shape index was bigger when the concentration of Fengda was 10 mg?L-1，and close to the oval.For small sized tomatoes，there was no significant differences（P<0.05）in fruits′ vertical diameter and horizontal diameter.The yield of big-sized tomato was about 4 548.33 kg per 667 m2，and was higher than other treatments，however，the yield of small-sized tomato was about 2 992.53 kg per 667 m2，and was higher than other treatments. Keywords:exogenous hormone;tomato;overwintering;fruit setting rate;deformity fruit rate
