An experiment was conducted to determine the influence of time grubbing in late spring–early summer, panicle developmental stage at grubbing, and presence or absence roots on grubbed plants, initial post-senescent viability fruits Nassella trichotoma North Canterbury, New Zealand. The percentage viable, following desiccation panicles removed from plants field, increased 1% for just beginning emerge leaf sheath, 49% fully extended grubbing. Similarly, as date delayed November (late spring) until December (early summer), fruit 0.3 47%. Overall, 36% were viable increasing slightly 47 44%, respectively, after a period with without being attached plant's root system. It concluded that if recruitment N. soil seed bank is be prevented must uprooted before extension. Delaying when are extended, while possibly enabling higher detected therefore destroyed, carries it high risk permitting bank.
