1. Development of Technique for the Light Emitting Diodes ovement of Light environment for the in light culture of Strawberry (Fragaria ×ananassa Duch.)
The strawberry of the vegatative propagation was produce daughter plant in generate runners. For the runner of occurrence from the mother plant was make use of them in the wintertime of pass through low temperature, then cultivated in long day and high temperature condition. The red/blue=5 LEDs light was installed at 1.2m height from ground surface, the lighting time was intermittent illumination the interval between lighting in 18:00～06:00. The mother plants of the lighting culture treatment were planting in the plastic greenhouse, and then daughter number ‘Sulhyang’ daughter was 25 in incandescent lamp treatment and ‘Redpearl’ daughter was 25.3 in LED BAR(red/blue=5) after 60 days. The plant height was longer in an artificial lighting than non treatment, also the runner number was many in them. The flower bud differentiation of the strawberry forcing culture was the important technique. The inducing condition of flower bud differentiation was low temperature and short day, and flower bud development was high temperature and long day. For inducing of flower bud differentiation the wave length was red/far-red. The daughter plant after lighting 20 days was setting in the plastic greenhouse, the 1st flower cluster emergence was 79%, the flowering was 69%.
2. Improvement of light environment for the Light Emitting Diodes in light culture of Strawberry(Fragaria ×ananassa Duch.)
The strawberry(Fragaria × ananassa Duch.) was usually cultivated in the form of lighting system at winter in the greenhouse. The illuminant which is used generally in the lighting system is the incandescent lamp. Light-emitting diodes(LEDs) are a potential irradiation source for intensive plant culture systems and photobiological research.
The role of infra-red, red, green, blue, red/far-red=5, red/blue=5 LEDs light and broad-spectrum incandescent lamp in plant growth and morphogenesis was investigated in strawberry(Fragaria × ananassa Duch. cv. Sulhyang) grown under approximately 100～150μ ㏖․m-2․s-1 photosynthetically active radiation(PAR) in LEDs.
Red/blue=5 LEDs light source extended plant height and leaf number at 45 days after light treatment, but there was not effet at 60 days after light treatment. There were larger leaf area under red/blue=5 LEDs than those of the others. The ascorbic acid contents were increased in quantity under red/far-red=5 LEDs and incandescent lamp and decreased in quantity under green LEDs. On the contrary total anthocyanin conents were increased in quantity under blue LEDs and decreased in quantity under incandescent lamp.
3. Establishment of Cultivation System for Improvement of the Light Environment of Strawberry(Fragaria ×ananassa Duch.)
The lighting culture continues its decrease trend owing to shallow dormancy cultivar in the forcing culture. The objective of lighting culture was stand the leaf stalk, increased the leaf area for the light interception character. The beginning time of lighting culture was around the middle of November and the suspending time of lighting culture was around the early in March. The time of them was 3 hours in night break(22:00～01:00). But the time and period of them was controled according to cultivar and culture environment. The lighting type was LED(red/blue=5), the wave length was red 660nm and blue 450nm. This type was put a LED bulb into the socket. The power consumption was 16W, angle beam was 120°. The red/blue=5 LEDs light was installed at 2m height from ground surface, the distance 3.75m, the arrangement W type in case of 10a(1 greenhouse). The strawberry plants was grown under approximately 2～4μ㏖․m-2․s-1 photosynthetically active radiation(PAR) in LEDs.
The sugar contents was an important points in fruit quality. The experiment was increased in red/far-red=10 LEDs and 13 percent higher than the non treatment and 8 percent higher than the incandescent lamp. Also vitamin C was increased in them. The anthocyanin content was increased in blue LEDs.
