The viability of seeds is tested by
A
$2, 6$ dichlorophenol indophenols
B
$2, 3, 5$ triphenyl tetrazolium chloride
C
$DMSO$
D
Safranine.
(NEET-2013)
Solution
(b) : Viability of seeds can be known by two methods: $(i)$ abilityto germinate, $(ii)$ testing their ability to respire. All viable seeds respire. This can be tested by immersing a section of seed containing the embryo in $0.1\%$ solution of triphenyl tetrazolium chloride. The viable embryo will turn pink due to conversion of colourless triphenyl tetrazolium chloride into insoluble coloured dye called triphenyl formazone due to reduction.
