Book excerpt: "The effect of the time of application of Gibberellic Acid (GA3) and Lipo-Chitin Oligosaccharides (LCOs) on annual production of globe artichoke (Cynara scolymus L.) cultivars 'Imperial Star' and 'Green Globe' was studied in 2000 and 2001. In order for flowering to occur plants must undergo a period of vernalization. In 2000, plants received 54 chilling (vernalizing) hours, an amount sufficient to induce flowering in 100% of the Imperial star and 25% of the Green Globe control plants. Applications of 25ppm GA3 at the 6 and 10-leaf stage reduced the time to flowering by 11 days, increased uniformity of flower bud production, and also increased yield of Imperial Star. GA3 had no significant effect on Green Globe plants. LCO fraction C (an identified and collected nod factor peak in retention time of 32.56 minutes) had minimal effect on growth and development for both cultivars in 2000. In 2001 plants received no vernalizing temperatures and in addition were exposed to 89 hours of temperatures greater than 32°C which could devernalize the plants. (Abstract shortened by UMI.)" --
