pitted, pubescent with tufts or lines of small hairs; hypogynium 3-lobed, the lobes oblong to lanceolate 1.
Because in the wind treatment, autonomous self-fertilization and, in the diurnal and nocturnal treatments, both wind and autonomous self-fertilization were not prevented, we calculated net production of achenes
for each vector of pollen (diurnal visitors, nocturnal visitors, wind, and autonomous self-fertilization) in the following way (Table 1): net production of achenes
due to wind ([A.
trigonous with elliptical or slightly obovate sides, the body 1.
Oil concentration and fatty acid composition of achenes
of North American Helianthus (Asteraceae) species.
Description: Fruits well preserved, light brown; Achenes
The upper row enlarged 6 times, the lower row showing the bases of achenes
enlarged 10 times
Fruits as a single seed called a caryopsis or rarely an achene
or a berry.
In Ruotsinsalmi the most common field crops are the achenes
and remnants of the pericarp of buckwheat (Fagopyrum esculentum), followed by glumes of common millet (Panicum miliaceum) (Fig.
Overcoming strawberry achene
dormancy for improved seedling production in breeding programs.
Diameter of 10 randomly picked heads were measured in cm with the help of a measuring tape and then averaged and then and then from the same 10 heads, number of achenes
were counted and averaged per head after manual threshimg.
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).
