The effect of ozone on pollen development in Lolium perenne L.

Abstract

Perennial ryegrass plants (Lolium perenne L.) were exposed in "Closed-Top Chambers" to different ozone concentrations and to charcoal filtered ambient air to study the effect of ozone on the development of pollen. Ozone at ambient (65 nl l(-1), 8h) and elevated (110 nl l(-1), 4h) concentrations affected the maturing of pollen by inhibiting starch… (More)
