Seediness as an invasive trait in Mimosa diplotricha Sauvalle in a tropical grassland.

Abstract

This paper presents the results of a study conducted in Assam, India, to evaluate the seed production trait of Mimosa diplotricha. M. diplotricha produced 128 ± 49.41 SE, at 95% CI (n=16) number of pod clusters per plant. Each pod cluster produced 30 ± 2.21 SE, at 95% CI (n=40) number of Mimosa pods with a range of 14-50 pods per cluster. Each pod produced 3 ± 0.11 SE, at 95% CI (n=400) seeds with a range of 1-6 seeds per pod. There was a significant relationship between the pod length and the number of seeds per pod. Out of the three seeds, 2 ± 0.15 SE, at 95% CI (n=400) seeds with a range of 1-6 were firm and healthy; while 1 ± 0.12, at 95% CI (n=400) seeds (range 1-5) were damaged per pod. Significantly more number of seeds (74%) were healthy than damaged (26%). An individual M. diplotricha plant produced an average of 13121 ± 5057, at 95% CI (n=16) seeds per plant with a range of 2457-42274 seeds.
