| Abstract:
A suspension of 1100 conidia of Botrytis cineria was inoculated into the stem zone and pericarp of mature, unripe kiwifruit. Infections developed in 40–100% of inoculations in the upper body of the fruit. A much smaller proportion (0–15%) developed rots with stem zone inoculation, Hyphae in the stem zone were observed in the region of inoculation. However, infections, once developed in the pericarp, readily spread through the stem region. Sequential extracts of the interior stem zone tissue contained water soluble, 70% methanol-water soluble and petroleum ether or ethyl acetate soluble compounds that inhibited mycelial growth. | |
