Nicotine is prepared from this part of Nicotiana tobacum

Assertion (A) : Self - sterility is observed in Nicotiana species. Reason (R) : Because the genes are located on chromosome.

Nicotiana sylvestris flowers only during long days and N.tobacum flower only during long days in the labortory undre different photoperiods , they can be induced to flower at the same time and can be cross fertized to flower aat the and can be corss fertillzed to produce self - fertile offsping .What is the best reason for considering N. syvestris and N . tobacum to be separate species

Nicotiana sylvestris flowers only during long days and N.tobacum flowers only during short days. If raised in the laboratory under different photoperiods. they can be induced to flower at the same time and can be cross fenjlized to produce self-fertile offspring. What is the best reason for considering N. sylvestfis and N. tobocum to be separate species?
