  • Mean (±1 SEM) seeds per capsule, mass per seed, and % viable seed from all N. attenuata plants that survived to produce seed from a plantation population and four natural populations (listed in order of decreasing probability of survival to seed production) with the exceptions described in Table 1. None of the values were significantly different (as determined by paired t tests) between induced and control plants of any populations (all P > 0.18). ND, not determined.
