Inhibition of Botrytis cinerea infection in kiwifruit tissues.

A suspension of 1100 conidia of B. cinerea was inoculated into the stem zone and pericarp of mature, unripe kiwifruit (cv. Hayward) harvested with their stems intact. 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 compared with pericarp inoculation. Hyphae were observed in the stem zone in the region of inoculation. Once developed in the pericarp, infections 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. This paper was presented at the Second International Symposium on Kiwifruit, held in Palmerston North, New Zealand, 18-21 Feb. 1991.
