Dormancy and germination of heteromorphic achenes
of Bidens frondosa.
At the achene
development stage (21 DAWDA), however, there was effect of the interaction of Base saturation versus B versus Water deficit.
Seed/Ovule ratio: To determine the S/O rate in the collected 25 capitulum, the mean number of disk flowers and filled achenes
per capitulum were reported as 33.1 and 11.7, respectively.
Vavilov and Bukinich described kafirstanica as truly wild, with tiny achenes
that were dark-colored and marbled, with an elaiosome.
Fruits as a single seed called a caryopsis or rarely an achene
or a berry.
of buckwheat (Fagopyrum esculentum) has previously been found from two sites in Finland, namely in Turku from 13th century and in Hameenlinna from 16th century layers (Onnela 2004, 70; Lempiainen T.
The productive potential of a head is measured in terms of number of achenes
Studies on achene
germination, transplantability, salinity tolerance, and cultivation of gumweed (Grindelia camporum) in hot and semi-arid conditions.
While most botanists are satisfied with external features of the achene
and a few researches have analyzed the development of the embryo and ovule, little attention has been given to the seed-coat of Asteraceae (Compositae) (CORNER, 1976).
Ecological correlates of achene
mass variation in Chrysolhamnus nauseosus (Asteraceae).
Indehiscent fruits include nutlets, achenes
, caryopsides, and cremocarps.
