Decalepis hamitonii Wight and Arn. is an important RET medicinal climber which is over exploited from its natural habitat for
its high valued roots. The roots are extensively used in folk and Ayurvedic medicines mainly as blood purifier and
hepatoprotective compound due to the presence of 2-hydroxyl-4-methoxy benzaldehyde (HMB). The work on propagation
and storage of seeds in this plant species is meagre for extending the cultivation and conservation. Therefore, the present study
was taken up. The two factorial experiment was conducted on the effect of media (top paper, between paper and cocopeat) and
temperature (20/ 30oC, 20oC, 30oC) on seed germination. Results revealed that the seeds placed at 20/ 30oC, tested on between
paper method has recorded maximum germination percentage (96.00%), root length (6.48 cm) and seedling vigour index
(955.77). Whereas, shoot length (10.40 cm), seedling length (16.14 cm), fresh (91.16 mg) and dry weight (8.76 mg) of seedling
was maximum in the seeds placed at 30oC temperature sown in cocopeat. No germination was recorded when the seeds were
placed at 20oC temperature sown in cocopeat. In an another experiment comprising of three factorial storage study on effect of
moisture content (8% and 6%), packaging material (aluminium pouch, polythene cover and butter paper cover) and storage
temperature (ambient temperature and 15oC) revealed that the seeds having 8% moisture packed in polythene cover and stored
at 15oC recorded maximum shoot length, seedling length and seedling vigour index I of 7.57 cm, 14.70 cm and 1373,
respectively. Shoot was not grown and minimum seedling length and seedling vigour index I of 3.60 cm and 172, respectively
was recorded in the seeds having 6 per cent moisture, packed in butter paper bag and stored at 15oC up to 90 days of storage.
Therefore, seeds kept for germination on between paper and placed at 20/30oC recorded germination. Whereas, seeds having
8% moisture, stored at 15oC packed with polythene and aluminium pouch was found better for maintaining viability and
vigour up to 90 days of storage.
