Improvement of Seed Germination Behaviour in Phyllanthus Amarus by Acid and Mechanical Scarification Pretreatments

Abstract

Phyllanthus amarus (Bhui-Aanwalaa: Family: Euphorbiaceae) is considered to be the most important medicinal plant of the Indian Thar desert. The present article deals with its seed morphological parameters, seed output, reproductive capacity (RC), germination behavior, seedling growth, root: shoot ratio (R/S ratio), germination value (GV) and vigour index (VI) in fresh and one-year-old seeds under controlled laboratory conditions. Results revealed that 73.33 and 60% germination was observed in fresh and one-year-old seeds as compared to the control (20% in fresh; while 36.67% in one-year-old seeds) after providing mechanical + conc. H2SO4 scarification for 2 and 1 min, respectively. The maximum VI and GV were obtained in mechanical + conc. H2SO4 scarification for 2 min pretreatments in fresh seeds.DOI: http://dx.doi.org/10.3126/eco.v19i0.9848EcoprintAn International Journal of EcologyVol. 19, 2012Page: 1-5Uploaded date: 2/14/2014

A novel approach for improving germination rate of Mucuna bracteata

“…The variations in the value of germination were numerically highly significant at a significance level of 0.05, because of stirring the blender for 4 minutes which gave the greatest value in peak value character which did not significantly differ with a blender stirring of 2 minutes for the mean daily germination value which caused the highest value. Gehlot and Kasera (2012) reported that the highest germination value was achieved in mechanical and concentrated H2SO4 scarification process for 2 min. Salvi et al (2015) stated that the pre-treated seed with scarification process performed better in respect to germination value in comparison with other treatments.…”
