Abstract/Contents:In 3 phytotron experiments 8 tropical grasses, 6 temperate grasses and an arctic grass were grown at day/night temp. of 15/10, 21/16, 27/22, 30/25 or 26/31 deg C. Increasing light intensity increased NAR ratio (LWR) and decreased leaf wt. in Paspalum notatum at 36/31 deg . In tropical grasses NAR increased with increasing temp. and LWR was greatest at the highest and lowest temp. Among tropical spp., Setaria sphacelata and Cenchrus ciliaris had a high LWR and low NAR at 15/10 deg indicating greater tolerance of low temp. In temperate spp. NAR decreased above 30/25 deg while in Trisetum spicatum and Poa pratensis it decreased above 27/22 deg and these 2 spp. did not tolerate high temp. At 36/31 deg the LWR in temperate grasses increased more markedly in spp. in which NAR decreased markedly. Tropical spp. which were able to adapt to low temp. had high NAR and low LWR at low temp. while temperate spp. able to adapt to high temp. had these characteristics at high temp. NAR was closely correlated with RGR and LWR was negatively correlated with RGR.
