| Abstract/Contents: | Tall fescue and perennial ryegrass were grown in 2-dm2 Wagner pots at soil temp. of 17 or 32 deg C in Dec., April or Aug. Growth inhibition by high temp. in Dec. and April was not marked, but in Aug. high soil temp. resulted in a greater reduction in dry wt. in perennial ryegrass than in tall fescue. In Dec., there were no differences in leaf water content of plants of both spp. with different soil temp. but in April, that of perennial ryegrass was reduced at 32 deg . High soil temp. did not affect stomatal opening, but inhibited transpiration in perennial ryegrass. It was concluded that poor growth of perennial ryegrass in summer is due to high soil temp. inhibiting water absorption by the roots, and high air temp. stimulating transpiration. |
