초록

The present study was carried out to investigate the effects of spermine treatment on the growth, yield and quality in strawberry under low-temperature condition, and thereby develop a chemical method to minimize damages by low temperature in greenhouse cultivation. Spermine treatment significantly improved the growth of strawberry in terms of leaf number, leaf area, leaf length, leaf diameter, plant height and plant weight. The highest effect was observed in the 250 uM spermine treatment and the effect tended to be maintained during the entire growth period of 90 days. Fresh weight and dry weight were significantly different depending on the concentrations of spermine. Strawberry plants treated with 250 uM spermine showed higher fresh weight and dry weight compared to untreated control plants during the growth period. Fruit weight, fruit length and fruit diameter were relatively higher when treated with 100 μM spermine compared to other treatments. The fruit yield was the highest with 14 fruits per plant at 250 μM spermine treatment and the coloration of the fruit was the best at this treatment with the Hunter a and b values of 46.56 and 28.75, respectively. The hardness of strawberry fruit tended to increase higher than 2N at 250 μM and 500 μM 250 uM spermine treatment. The sugar content of strawberries treated with 250 μM spermine was 9.5 ° Bx which was 1.6 ° Bx higher compared to that in untreated control. However, spermine treatment did not affect the acidity of fruit and it remained 0.68-0.76% regardless of treatment concentrations. These results suggest that spermine treatment has a positive effect on the growth and productivity of strawberry fruit under abnormal low-temperature condition. The positive effect was the highest at 250 μM spermine treatment and gradually decreased in the order of 100 μM, 500 μM, and untreated control.
