Leachates of living Cynodon dactylon (L.) Pers. and Amaranthus sp. were applied to Carya illinoinensis (Wangenh.) C. Koch. seedlings to compare effects on growth and elemental absorption. Water applied to the weed pot or control pot (no weeds present) leached through the pot and into a funnel with a tube attached, then directly into the corresponding pecan seedling pot. After 4 months of growth, pecan seedlings receiving weed leachates had less leaf area and were shorter than those watered through control pots. These results suggest that leachates from these two weed species inhibit pecan growth, independent of any competition effects.
Bermudagrass ( Cynodon sp.) and zoysiagrass ( Zoysia sp.) are important warm-season turfgrasses and are widely used for sports fields, golf courses, and lawns in tropical, subtropical and transition zone climates ( Hanna et al., 2013 ). Although

( Marcum, 1999 ). Bermudagrass ( Cynodon sp.), belonging to the Chloridoidea, is one of the most important and widely adapted warm-season turfgrasses. Bermudagrasses have shown moderate salinity tolerance when subjected to varying concentrations of
rain shelter returned to its center position. Grasses evaluated in this parent study included eight cultivars of bermudagrass ( Cynodon dactylon sp.) (‘Celebration’, ‘Common’, ‘GN-1’, ‘Grimes EXP’, ‘Premier’, ‘TexTurf’, ‘TifSport’, and ‘Tifway’); seven
; Trappe et al. 2011 ). For example, bermudagrass ( Cynodon dactylon ) is widely regarded as having poor shade tolerance and may require over 20 mol·m 2 ·d −1 of photosynthetically active radiation (PAR) to form an acceptable lawn ( Chhetri et al. 2019
Chilling injury (CI) can occur in susceptible turfgrasses, such as bermudagrass ( Cynodon sp.), as a result of nonfreezing low temperature stress. Bermudagrass is a warm-season turfgrass predominantly grown in the southern and transition zone
