Description The laboratory experiments were conducted in department of Seed
Science and Technology, UAS, Bangalore to know the effect of
invigouration treatments on enhancing seed quality parameters of
naturally aged seed lots maize and cotton.
Seeds primed with KH2PO4 at 1 per cent recorded higher seed
quality attributes in maize and cotton viz., germination (88 & 79 %), field
emergence (70 & 66%), amylase activity (0.782 & 0.776 ), TDH (1 .71 &
2.95) and lower EC (0.288 & 2.95 dS/m) respectively.
Seeds primed with KH2PO4 at 1 per cent recorded higher seed
quality attributes in maize and cotton viz., germination (63% & 64%),
field emergence (49% & 58%) , amylase activity (0.722 & 0.71 ), TDH
(1.450 & 2.63) and lower EC (0.245 & 0.30dS/m) followed by
hydropriming at the end of 6 days of aging period and lowest was
recorded in non primed seeds.
Seeds primed with KH2PO4 at 1 per cent recorded higher
germination (66 % in L1), field emergence (49 % in L3), TDH (1.66 in L3)
and lower EC (0.26 dSm-1 in L1) after six months of storage in maize, and
lowest seed quality attributes were recorded non primed seeds. In cotton
higher seed quality attributes viz., (64% L1, 58% L1, 2.33 in L3) and lower
(0.31 dSm-1 in L1) were registered, and lowest seed quality attributes
were recorded non primed seeds. Hence, the study revealed that 1 per
cent KH2PO4 priming enhanced seed quality parameters of naturally aged
seed lots maize and cotton.
