Effect of Light during Vernalization on Flowering of Stocks (Mathiola incana)

Abstract

1. The influcence of light during vernalization on stock (Mathiola incana) was studied with varieties, Hatsuyuki, Ball's Lavender, American Beauty and Branching Peace.
2. Continuous lighting during chilling at 10°C resulted. in a high percentage of budding and flowering, while artificial short day (8 hours) resulted in a low percentage.
3. Light given prior to vernalization affected budding. Namely, the percentage of budding was higher in the plants that received continuous lighting at young stage than those that received short day-length.
