Morphological and metabolic differences between turfgrass and row‐crop biotypes of goosegrass ( <i>Eleusine indica</i> )

The research was conducted to evaluate Eleusine indica (L.) Gaertn. (goosegrass) phenotypic diversity in biotypes collected from managed turfgrass, noncrop, and row crop environments. A common-garden experiment quantify morphological characteristics. Biotypes were primarily distinguished along a single principal component that separated taller growing types with lower tiller numbers, larger leaves, more spikelets per seedhead, contrasted turfgrass noncrop shorter height, greater tillering, fewer seedhead but total seedheads. dwarf phenotype of E. (Texas-GCPG) golf course putting green having internodes, distinct phenotypically compared all other biotypes. Plant growth regulators tested on cropping environment (PBU-crop) (RB-GC Texas-GCPG). Gibberellin inhibitors (paclobutrazol, flurprimidol, trinexapac-ethyl) had negative impact the three Furthermore, application GA3 (gibberellin A3) increased Texas-GCPG height nontreated plants, suggesting it is GA-sensitive mutant. Molecular biochemical such could shed light pathways mutations any causal gene/s prohibit or reduce active gibberellic acid production.
