Abstract
The present investigation was carried out on Rohida seeds.
The seed material was collected from four different seed sources
viz., Churu, Ding Mandi, Jhumpa and Rajgarh. The present study
was conducted during 2005-06 at nursery area of Department of
Forestry and laboratories of Department of Seed Science and
Technology and Department of Forestry CCS HAU, Hisar. The
objective of investigation was: To evaluate different seed sources
for seed viability, germination and seedling growth behavior; To
determine the storability of Rohida seed.
Various morphological characters of Rohida trees from four
different geographical locations were recorded and seeds were
collected from the selected trees. Seed quality parameters such as
seed size (length and breadth), colour, test weight, germination
percent (74 %), speed of germination (13.63 %), radicle (6.30 cm)
and plumule length(5.30 cm), seedling dry weight (415.60 mg),
dehydrogenase activity (1.40), electrical conductivity vigour index
I and II were studied of freshly harvested seeds and then stored in
ambient storage conditions. The seeds of all the four different
places were aged artificially at various time (24, 48 and 72 h) and
temperature (40±1oC) variables. Accelerated ageing of seeds for
24 h at 40±1oC produced a clear separation and provide better
results. Then seeds of all the four different places were tested to
study physiological basis for loss in viability. It was observed that
standard germination, seedling length, dry weight, vigour index I,
vigour index II and viability percentage was found maximum in
Rajgarh seed source.
