The effect of temperature on isolated rat liver perfusion was studied. Livers were perfused for 12 hours with oxygenated Krebs-Henseleit solution at 5, 10, 15, 20, 25 and 30 degrees C, followed by one hour normothermic reperfusion. After each perfusion, oxygen consumption, liver enzyme release, tissue swelling, energy metabolism and histopathological abnormalities were determined. Compared to t...

abstract this experiment, conducted to examine the effects of temperature and photoperiod on seed germination of watergrass (echinochlo aoryzoides) as a new-introduced and barnyardgrass (e. crus-galli) as a common weed species in rice fields of guilan province. this study was consisted of two separate experiments. at the first study, germination responses of two species to different temperature...

Meloidogyne chitwoodi and M. hapla were pathogenic to both roots and tubers of Russet Burbank potato. Both species affected root growth at 15, 20, and 25 C, but not 30 C. Meloidogyne chitwoodi reprotluced best at 15, 20, and 25 C and M. hapla at 25 and 30 C. Reproduction of M. chitwoodi was reduced at 30 C; reproduction of M. hapla was reduced at 15 C and less at 20 C. The reproductive potentia...

The paper presents the results of testing seed germination and initial growth seedlings four sunflower hybrids: 2950, 2951, 3007, 3009) at different temperatures: 20° C, 25°C, 30°C. In all hybrids tested, highest seeds was achieved a temperature 30° C; however, in two tested (2950 3007) no significant difference (p ≥ 0.05) found between C 25° C. Correlation interdependence stem positive statist...
