Description A laboratory experiment on “Effect of priming on seed quality and
storability of brinjal (Solanum melongena L.)” was conducted at National
Bureau of Plant Genetic Resources (NBPGR), Hyderabad and Department of
Seed Science and Technology, College of Agriculture, Rajendranagar,
Hyderabad during the year 2011-12. The experiment was carried out in two
varieties of brinjal viz., Bagyamati and Pusa purple long in Factorial Completely
Randomised Block Design (FCRBD) comprising two factors viz., vigour level
of the seed and another as priming method for each variety with four
replications
Five treatments viz., halo priming, hydro priming, osmo priming, sand
matrix priming and unprimed as control as one factor and two different vigour
levels of the seed viz., Mediun vigour (seed artificially aged for 13 days) and
20
high vigour (seed artificially aged for 3 days) as another factor. Seed samples
were primed and kept in aluminium pouches and stored for eleven months at
ambient conditions.
The treated seeds were used to observe different physiological and
biochemical changes for every two months up to eleven months of storage in
each variety separately. The samples were drawn at bimonthly intervals for
assessing the seed quality parameters viz., seed weight, moisture content, seed
infestation, germination percentage, mean germination time, seedling emergence,
seedling vigour index I and II (on seedling length and dry weight basis), field
emergence and electrical conductivity, lipid peroxidation, phosphatase activity
and dehydrogenase activity.
The seed which is artificially aged for 3 days with high vigour recorded
higher germination percentage, field emergence, speed of germination, and
seedling vigor index I and II (on seedling length and dry weight basis) and least
was recorded in seed that is artificially aged for 13 days in both the varieties.
Among the priming treatments, sand matrix priming of seed (80%WHC) resulted
in best performance of the seed regarding all the physiological and biochemical
parameters followed by hydro priming. Unprimed seed (control) failed to exert
any significant influence on the quality parameters.
Storage of the treated seeds up to eleven months resulted in a gradual
decrease in performance of the seed for both the varieties. However, storage of
the high vigour seed that is primed in moist sand (80%WHC) up to eleven
months was found to be good compared to medium vigour seed (artificially aged
for 13 days) regarding all the quality parameters irrespective of the variety.All
the four priming treatments significantly improved the quality and storability in
both varieties of brinjal over the unprimed ones. Among them, sand matrix
priming recorded supremacy over the other treatments followed by hydro
priming.
