STRASBURGER records some curious experiments in intergrafting various herbaceous Solanaceae. Thus he successfully grafted species of stramonium and common tobacco plant, henbane, Atropa belladonna, and petunia upon the common potato plant. Grafts of Datura stramonium and Nicotiana tabacum took remarkably well, the plants growing freely and coming into flower. Tschudy, however, long ago, had grafted Lycopersicum upon a potato stock, and so had gathered potatoes from the bottom and tomatoes from the tops of the same plant; but this is not so extraordinary, the two plants being so essentially congeneric. The most remarkable result of Strasburger's trials was that, when Datura stramonium was grafted upon a potato plant, the potatoes borne by the latter, to all appearance normal, were found to be impregnated with atropine. He does not say whether those grafted into Nicotiana tabacum had their tubers infected with nicotine.—American Journal of Science.
