This experiment has investigated the effects of silicon on albinism of strawberry. Albino fruit appeared after a month of treatment of potasium silicate(Si) in nutrient solution. When $200mL{\cdot}L^{-1}$ of Si applied, number of albino fruit increased over 90% of total amount of fruit, and the symptom remained latest any other treatment. The fruit length of the strawberries in Si treatments were longer than control treatment. However, the diameter and weight of fruit decreased in treatment of Si. The soluble solids of fruits, numbers of fruit and yield per plant were no significant differences among treatments. The rate of albino fruit was significantly increased with increase of concentration of Si. The results of this experiment will be utilized for the cultivation in the new substrate application for strawberry hydroponics.

Experiments were conducted to evaluate the effect of low temperature-darkness treatment on floral initiation in four kinds of Korean strawberry cultivars. Mother plants were planted on March 29 and daughter plants were raised for the experiment. Temperature treatment was done for 7, 14, and 21 days keeping $13^{\circ}C$ in cooling storage from August 29, September 5 and September 14 to September 21. After the treatment, flower bud initiation was examined by a microscope, and the seedlings were transplanted on hydroponic system with Yamazaki's strawberry solution of EC $0.8dS{\cdot}m^{-1}$ to check the flowering. 'Ssanta' and 'Maehyang' showed early flower bud initiation in 7 days treatment than 'Seolhyang' by microscope check. 'Ssanta', 'Daewang', and 'Maehyang' showed early flower bud initiation in 14 days treatment than 'Seolhyang'. There were no differences among the treatments in 21 days treatment. Percentage of flowering of 'Seolhyang' and 'Maehyang' by low temperature-darkness treatment didn't show any difference but 'Daewang' and 'Ssanta' showed high percentage of flowering. It suggested that low temperature-darkness treatment technique can be use for improving early flowering and yield of 'Ssanta' and 'Daewang' cultivars.

In this study, the effect of crown heating on the cultivation environment, budding, flowering and yields of strawberry was analyzed. In December, January, and February, when the outside temperature was low, the average strawberry crown temperature at daytime in the test zone was 1.3℃ higher than that in the control zone, and the average strawberry crown temperature at nighttime in the test zone was 2.7℃ higher than that in the control zone. The average bed temperature at daytime in test zone was 1.7℃ higher than that in the control zone, and the average bed temperature at nighttime in test zone was 2.4℃ higher than that in the control zone. As a result of performing correlation analysis and regression analysis on strawberry crown temperature and budding period, the correlation coefficient was -0.86, which tended to be shorter as the crown temperature was higher, and the determination coefficient was 0.74. The total yields of strawberry during test period were 392.6 g/plant for test greenhouse and 346.0 g/plant for control greenhouse respectively. As for the quality of strawberries, the ratio of 2L (very large) grades and L (large) grades was 62.4% in the test greenhouse and 58.5% in the control greenhouse, indicating that the proportion of high quality strawberries was higher in the test greenhouse.
