Effects of a stay-green mutation on plant nitrogen relations in Lolium perenne during N starvation and after defoliation.

Annals of botany - 1 Jan 2002

Macduff J H, Humphreys M O, Thomas H

Abstract excerpt

The stay-green mutation of the nuclear gene sid results in inhibition of chlorophyll degradation during leaf senescence in grasses, reducing N remobilization from senescing leaves. Effects on growth of Lolium perenne L. were investigated during N starvation (over 18 d) and after severe defoliation, when leaf growth depends on the remobilization of internal N. Rates of dry mater production, partitioning between...
