Abstract

Abstract Not Available – First paragraph follows: Lettuce seeds that have a high germination percentage are not always high in vigor. Low vigor seeds may germinate and emerge from the soil acceptably under favorable conditions, but under unfavorable situations they perform poorly. In recent years, most lettuce growers in the central coast area of California have been using reduced seeding or precision planting techniques. With a reduction in the number of seeds planted per acre, the quality of seeds both in terms of germination and vigor becomes more critical. Rapid emergence of seedlings during the critical stages of emergence, and establishment of the tender plant, is important to help reduce stand losses due to soil crusting, insect and fungi attack.
