achene

If the structure of genetic relationships among populations is correlated to achene morphology, we can statistically remove genetic distances when comparing morphology and environment.

Overcoming strawberry achene dormancy for improved seedling production in breeding programs.

The only taxa where the developed prophyll accompanies the achene are Lipocarpha.

Water deficits conditions reduced the head diameter, number of achenes per head, 1000-achenes weight and finally achene yield of sunflower hybrids (Hussain et al.

Achene were counted and averaged to calculate the number of achenes per head.

Days taken to germination, flowering, achene's formation and physiological maturity and Achene, s yield as affected by sunflower hybrids, planting densities and nitrogen rates.

Achene tuberculate and papillate; glabrous; hypogynium with 6 globose tubercles in distinct pairs 3.

cordillerana are unclear and the species can not be placed into any one of the subgenera of Eleocharis recognized by Gonzalez-Elizondo and Peterson (1997), The glossy surface of the achenes and the floral scales that fall before the achenes remind of those in Eleocharis uniflora Seberg, another species of uncertain affinities originally described into a separate genus (as Chillania pusilla Roiv.

Perianth bristles usually 6, subequal, most of them well exceeding the middle of the achene body .

THE ACHENES (seeds) of cultivated or common sunflower (Helianthus annuus L.

Description: Opercle of achene keeled and winged, ventral margin wavy, beak ventral.

Ecology of the achene dimorphism in Heterotheca latifolia.

The fruit is an achene, whose peduncle develops into a pseudo-fruit that can be 24 cm in length and 2-3 cm in diameter, with a weight of 5-12 g and coloration ranging from yellowish to reddish (Ferreira, 1973; Paula & Heringer, 1978).

Each flower the produces a single , one seeded hard shelled fruit called achene, that is what gives the fig the crunch we all know and admire.

Edwards and Vavasseur (1829) first referred to the seed as an achene.
