GERMINATION AND SEEDLING RESPONSE OF ATLANTIC AND GULF COASTS POPULATIONS OF UNIOLA PANICULATA

摘要: A B S T R C Germination response following various periods of cold treatment and seedling to temperature, daylength, salinity were studied for several Atlantic Gulf coasts populations Uniola paniculata L. Results indicated that coast Florida did not require prior germination at 95-65 F, but from Virginia North Carolina did. exhibited a intermediate between those just mentioned. Seedling studies revealed alternating diurnal thermoperiods with daytime temperatures 80 F above produced good vegetative growth in all little preference either short- or long-day conditions. the most biomass under -all Seedlings population no difference substrate salt tolerance. Salt tolerance was reduced higher temperature thermoperiod both populations. these two more spray than treatments. THE PERENNIAL DUNE grass
