Abstract
Removal of atmospheric carbon dioxide enhanced penetration of seedling wheat by stem rust Puccinia graminis in light and dark but did not materially affect penetration by leaf rust P. recondita. A concentration of 5 percent CO2 nearly suppressed penetration by P. graminis but not by P. recondita. Thus light may promote penetration by P. graminis through photosynthetic reduction of CO2 within the leaf and P. recondita may penetrate independently of light because it is relatively insensitive to the effects of CO2.This publication has 0 references indexed in Scilit:
