The callus is not formed in
tissue culture
suspension culture
clonal propagation
sexual reproduction
Through which method more numbers of female plants can be produced in papaya?
Spraying ethephon
Genetic engineering
Polyploidy breeding
Tissue culture
Hardening in tissue culture is
keeping at 30-50ºC temperature for about 30 minutes.
acclimatization tissue culture plants slowly before growing in the field.
plunging the vials into water at 37-40ºC
none of the above
Part of the plant,which is cultured to obtain virus free clones,is
leaf
root tip
shoot tip
embryo
In callus culture,roots can be induced by the supply of
auxin
cytokinin
gibberellin
ethylene
A nutritionally wild type organism, which does not require any additional growth supplement is known as
phenotype
holotype
auxotroph
prototroph
In tissue culture,roots can be induced by
lower concentration of cytokinin and higher concentration of auxins.
only cytokinin and no auxins
no cytokinin and only auxins
higher concentration of cytokinin and lower concentration of auxins
Axenic culture is
pure culture of a microbe without any nutrient
pure culture without any contamination
culture of tissue
culture of gene
Phytotron is
a controlled condition chamber for tissue culture
leaf culture process
special culture of plants
root culture process
Differentiation of organs and tissues in a developing organism, is associated with
developmental mutations
differential expression of genes
lethal mutations
deletion of genes
