Abstract/Contents:"Lack of water availability due to drought stress can be detrimental to plant health and overall growth. Drought stress can cause dormancy or mortality of meristematic tissues contained within the crowns or stolon nodes of creeping bentgrass (Agrostis stolonifera), which are critical growing points. Such damages may inhibit tillering as well as growth of new or established daughter plants during prolonged or severe drought stress. Therefore, the ability for regrowth upon re-watering is critical to overall plant survival and persistence after a period of drought. Plant hormones, such as gibberellic acid or cytokinin, which play a role in plant growth and elongation, may be associated with increased regrowth potential upon post-drought recovery; however, hormonal regulation of regrowth from tillers or stolons is still unclear. Therefore, this study focuses on determining the effects that exogenous applications of gibberellic acid (GA3), cytokinin (6-BA), and the two hormones combined can have on regrowth during post-drought recovery and the roles they play in regulating rapid recovery. Upon re-watering, this study found that both GA3 and 6-BA promoted turf quality and rapid regeneration of new tillers and stolons. How hormones may contribute to rapid post-drought recovery in creeping bentgrass will be discussed."
