Abstract
A laboratory experiment was conducted in factorial completely randomized design with four repetitions in the Laboratory of Seed Science and Technology, Junagadh Agricultural University, Junagadh from 22th April to 2nd December, 2013 to study the “Effect of seeds storage containers and seed treatments on seed quality in chickpea [Cicer arietinum L.]” during three storage periods (75, 150 and 225 days of storage).
The fresh seeds of three chickpea genotypes viz., GG 1, GJG 3 and GG 4, obtained from Pulse Research Station, Junagadh Agricultural University, Junagadh were treated with thirum, dry neem leaf powder and castor oil and stored in three types of seed containers i.e. single polythene bag (400 gauge), double polythene bag (400 + 400 gauge) and gunny bag in laboratory under ambient conditions. A control (without seed treatment) also runs simultaneously. At 75, 150 and 225 days of storage periods the germination percentage, first count of seed germination, speed of germination, shoot length of seedling (cm), root length of seedling (cm), seedling length (cm), seedlings fresh weight (g), seedlings dry weight (g), strong seedlings, weak seedlings, seed vigour index (length), seed vigour index (mass), test weight (g) and seed moisture per cent were determined.
The results of present investigation revealed that the genetic make-up of genotype GG 4 was found to be significantly superior to that of GG 1 and GJG 3 in respect of maintenance of seed viability and vigour, during the storage. Genotype GG 4 recorded significantly higher values of germination percentage, first count of seed germination, speed of germination, shoot and root length of seedling (cm), seedling length (cm), strong seedlings, seed vigour index (length) and lower values for weak seedlings, test weight (g) and seed moisture per cent. Genotype GJG 3 recorded significantly highest values for fresh weight (g), dry weight (g), seed vigour index (mass), test weight (g) and seed moisture per cent.
As regards the seed treatments, thirum seed treatment helped to maintain higher germination percentage, first count of seed germination, speed of germination, seedlings fresh weight (g), seedlings dry weight (g) and strong seedlings, while seed treatment with dry neem leaf powder helped to maintain higher shoot and root length of seedling (cm), seedling length (cm), seed vigour index (length) and lowest weak seedlings and seed treatment with castor oil recorded significantly lowest test weight (g).
In case of seed containers, double polythene bag seed container was found superior than rest of other containers by recording higher germination percentage, first count of seed germination, speed of germination, root length of seedlings (cm), seedling length (cm), strong seedlings, seed vigour index (length) and lowest weak
seedlings, test weight (g) and seed moisture per cent, while seeds stored in single polythene bag recorded significantly highest shoot length of seedling (cm), seedlings fresh weight, dry weight (g) and seed vigour index (mass). Seeds stored in gunny bag container had low values for all seed quality parameters and highest values for test weight (g) and seed moisture per cent.
In case of storage study it was observed that most of the seed quality parameters i.e. weak seedlings, test weight (g) and seed moisture per cent increased with further increase in the storage periods, while germination percentage, first count, root length and shoot length of seedlings (cm), seedling length (cm), seed vigour index (length), seed vigour index (mass), strong seedlings decreased with increase in storage periods, however speed of germination, seedlings fresh weight (g), seedlings dry weight (g) increase up to 150 days of storage periods then after decreased with further increase in storage periods.
Seeds of GG 4 treated with thirum and stored in double polythene bag maintain highest germination percentage, first count of seed germination and speed of germination, seed vigour index (length), while highest strong seedlings was recorded by GG 4 seeds treated with thirum and stored in single polythene bag.
Thus, from the results of the present study, it seems quite logical to note that the present recommendation of thirum for seed treatment and double polythene bag for packaging of chickpea seeds appears suitable for maintaining seed quality. Seeds of GG 4 treated with thirum and stored in double polythene bag, displayed the enhanced storability.
