Growth and nutrient relations were examined in healthy leeks and in leeks inoculated with the rust, Puccinia allii, to give three different intensities of infection (i.e. 10, 20 and 30%). Experiments were conducted over an 8-week experimental period,

Antagonistic fungal isolates (AP1.S20, AP2.R16, Z1.S23 and AP2.R19), from root and soil samples of faba bean crops, inhibited mycelial growth of Botrytis fabae in vitro by up to 44·9%, producing clear inhibition zones. Spore suspensions of isolates

SUMMARY Uptake of the polyamine biosynthesis inhibitor, α-difluoromethylornithine (DFMO), by barley seedlings was examined. DFMO was taken up by intact roots and approached saturation at a rate of 780 mol m−12g−1d.wt. The uptake as a function of
