Q.1
Statement 1 : Desiccation sensitive seeds are not preferred for cryobanking
Statement 2 : Desiccation tolerant seeds with high oil content may be preferred for long-term storage in the traditional
genebank
Q.2
Statement A : — Study on desiccation and freezing tolerance of explant is not much important in developing suitable
cryopreservation protocol
Statement B : Cryoprotectants are used to avoid ice crystal formation, however, can be toxic at high concentrations
Q.3
Statement A : — Slow freezing involves slower cooling rates while vitrification involves rapid cooling
Statement B : Rapid thawing is used to prevent the formation of ice crystals during sample rewarming
