However, the potential seed production levels at these sites were greater than at HQB.

Thus, in addition to direct interception on stigmas, filamentous pollen can be captured while they rotate past flowers or when they are redirected through the velocity gradient towards flowers. This item is part of JSTOR collection Thus, the population of Z. japonica at HQB was maintained by asexual reproduction.

The allocation to sexual reproduction at SLL was greater than at HQB. Mar. 19, 307–327. The translational movement of pollen was imparted by the advection of the fluid (e.g., pollen kinetic energy, K, ranged from 0.8 x 10-14 to 2.4 x 10-14 J, and the average K of the fluid was ≈ 0.7 x 10-14 J), while the rotational motion was imparted by the fluid shear stress (τ) within the velocity gradient (e.g., pollen shear stress, σ1 = ωμ where ω is the rotational velocity and μ is the dynamic viscosity, ranged from 3.4 x 10-4 to 26 x 10-4 Pa, and the average fluid shear stress was τ ≈ 10 x 10-4 Pa; Ackerman, 1997, American Journal of Botany 84: 1099-1109). Flow chamber observations of the filamentous pollen of Zostera marina L.

A mixed mode of submarine and surface hydrophilous pollination occurs in the seagrass Zostera marinaL. We also observed a large amount of seed coats in SLL.
