Abstract/Contents:"Shade can be detrimental to turfgrass and cause changes in growth habit and leaf morphology. Low levels of light may also affect the activity of natural plant growth regulators. This study was initiated to evaluate the effects of three nitrogen levels, two growth retardants (tri-nexapac ethyl and ethephon) and a flutolanil on shaded mixed stands of Kentucky bluegrass and perennial ryegrass. Percent coverage, quality, and root mass weight measurements were taken at two sites. The effect of location on root weight was significant. A consistent PGR by location interactive effect was observed on both quality and percent cover. A natural stand of deciduous trees created a graduated shade effect from north to south at one location so the experiment was designed to block replications with the shade. The effect of graduated shade was evident in significant replication effects and interactions of replication with PGRs, nitrogen and the fungicide for clipping yield, verdure weight and shoot density at that location. Results of the study suggest that the effect of PGRs on turfgrass growth under shade is not necessarily the same as under full sun and that complex interactions of PGRs with fungicides and nitrogen occur in shade."
