Initiation of Germination Characters of Plant Seed by Light Quality
초록
Germination characters of the lettuce seed that received photoperiodic pretreatments of low or high temperature from the flowering to harvest. MSU-15 seed, one of the lettuce cultivars used, having high dark germination, was modified to low dark germination by the long-day treatments during the seed formation. Light-requiring MSU-16 seed was modified to the dark-germination seed by high temperature given at the seed formation period. Above results suggest that the environmental conditions given to an immature seed adhered to a mother plant bring about some modification to its native germination habit. I confirmed that the spectral quality of light could influence the phytochrome system which controlled germination characters of the progeny of lettuce seed ; plants grown in light rich in far-red energies produced light-requiring seed, but those grown in high deficient in far-red energies produced dark germination seed.
