MadSci Network: Botany |
One good student experiment involving alcohol effects on plants involves paperwhite narcissus, which are sold around Christmas to force indoors. A common problem with forced paperwhite narcissus is that the stems and leaves grow too tall and fall over. A Cornell University researcher found that irrigating the plants with a 4 to 6% solution of hard liquor or rubbing alcohol stunted the growth so the stems and leaves did not get too tall.
