Seedlings of Nymphaea coerulea, N. lotus and Nuphar luteum were examined for monocoty-ledonous and dicotyledonous characters. The cotyledonary formation could be interpreted either as a single bilobed structure or as two separate cotyledons. However, the presence of an operculum and the recognition of a coleoptile and mesocotyl similar to those of ...

The carotenoids of corn seedlings
Archives of Biochemistry and Biophysics, 1952A qualitative and quantitative method for examining the carotenoids in corn seedlings was developed. The method involves: (a) extraction of the pigments with acetone and hexane; (b) Chromatographic separation of the pigments utilizing calcium hydroxide, sucrose, and magnesium oxide; and (c) characterization of the pigments by their spectrophotometric ...

Orchids are notorious for the prodigality of their tiny seeds. Over a hundred years ago Darwin recorded an average of more than six thousand seeds in the capsule of a small British orchid, and reported another botanist’s count of nearly two million in a Maxillaria from South America. The record seems to be held by another South American species, of the
