Spikelet seed position-dependent effects on life history

Spikelet seed position-dependent effects on life history - Eremopyrum distans
Eremopyrum distans

The cold desertannual grass Eremopyrum distans exhibits position-dependenteffects of seeds in the spikelet. Wang et al. (pp. 95–105)find that seeds from three positions in a spikelet differ inmorphology, mass and in percentage and rate of seed germination,and the plants derived from them differ in growth and seed production.Distal seeds appear to represent a ‘high-risk’ lifehistory strategy and basal seeds a ‘low-risk’ strategy.
