Sažetak
We report the first record of vertical rhizome growth in the temperate seagrass Zostera marina. In a population of Z.marina occurring on subtidal sand in the Novigrad Sea (Croatia), an area subject to episodic high sediment transport, collected plants of Z.marina showed vertical rhizomes with shorter and narrower inter-nodes (mean length=3.4 +/- 1.5SD mm, mean width=1.9 +/- 0.3SD mm) than those recorded for horizontal rhizomes (mean length=9.0 +/- 3.5SD mm, mean width=2.8 +/- 0.4SD mm). Out of a sample of 1130 rhizome fragments, 288 (25.5%) were vertical. Repeated moderate burial events may have stimulated the production of vertical rhizomes, and the ability of Z.marina to produce vertical rhizomes may enable it to withstand moderate burial in this highly dynamic environment.
