Early seedling demography in balsam fir seedling banks
Canadian Journal of Forest Research, 1999Following the 1995 mast year, we conducted detailed seedling demography surveys to characterize some ecological factors affecting germination and early establishment in understory balsam fir (Abies balsamea (L.) Mill.) seedling banks and verify if recruitment from a cohort can potentially renew the balsam fir seedling bank.

The Seed and the Seedling [PDF]
The obligate parasites can only germinate in the vicinity of host roots. Their minuscule seeds contain a reduced embryo that in some genera lacks cotyledons. The fine structure of the seed, its accumulation of nutritional reserves and the role of the labyrinthine wall in the endothelium are amongst the various seed aspects that are described and ...

Botanical Journal of the Linnean Society, 1975
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
