A Histochemical Determination of the Nature of the “Droplets” in the Generative Cell in vivo

抄録

1. So-called “droplets”, found in the generative cell of Amaryllidaceous and Iridaceous plants by the present writer, were investigated in the living state by the help of chemical, micro-spectroscopic and luminescence microscopic analysis.
2. The yellow or brownish yellow “droplets” in the generative cell of Narcissus Tazetta, var. suisen, contain two kinds of carotinoid dye, an unknown substance absorbing green-yellow light, and an orangered luminescent substance, and are rich of lipoid but contain no chlorophyll.
3. It is concluded that the “droplets” are yellow chromoplasts. And the relation and connection with the results by other authors were considered.
