“…There is evidence to suggest that the depth distribution of the vascular plants, unlike the more primitive ones, is confined to depths less than 10 m (Maristo 1941, Gessner 1961, Hutchinson 1975, Wetzel 1975. This has been supported by some oft-quoted experimental studies which reported that plants grew poorly when subjected to pressures equal to or exceeding those at maximum depth (Gessner 1952, Ferling 1957.…”

“…Short experimental periods tend to emphasize the shock effect. The differences due to elevating the pressure are reported as being much more dramatic in Hippuris vulgaris L. after one week than those after 60 days in Cabomba aquatica and Myriophyllum brasiliense (Gessner 1952). Other factors, however, may also reduce the differences in growth after long periods in a limited environment.…”

“…For freshwater aquatic vascular plants hydrostatic pressure has traditionally, since the time of A. F. W. Schimper (1854), been considered of signal importance, particularly influencing flowering and heterophylly (Gessner 1952, Ferling 1957. Arber (1920) does not follow this tradition, nor is pressure considered to be a significant factor influencing the leaf form in Potamogeton richardsonii (Spence & Dale 1978).…”

These experimental studies have shown that this plant will grow successfully at pressures encountered in water at depths as great as 17 m. When there were suitable levels of light, temperature, nutrients and aeration, the plants grown under constant hydrostatic pressure for three weeks showed variations in the measured amounts of new growth but no measure could be associated with the constant increased hydrostatic pressure. Sudden changes in pressure are thought to play a significant role in aquatic plant growth under experimental conditions.

“…Therefore, under changing conditions it might be beneficial to submerged plants to register water depth and to regulate shoot elongation accordingly. Since hydrostatic pressure increases and light intensity decreases with water depth (Gessner, 1952;Dale, 1984), we investigated the influence of these two factors on underwater shoot elongation.…”

“…Plants tended to elongate more in deeper water during the first week, but this was usually non-significant (Table 3). Until now, studies on the effects of hydrostatic pressure on plant growth (Gessner, 1952;Ferling, 1957;Dale, 1981Dale, . 1984 have mostly been made usmg aquatic species, and were aimed at explaining the depth distribution of these species in the field by investigating their tolerance to very high hydrostatic pressures, with effects found only at pressures similar to water depths of 5 m or more, which exceed tbe maximum depths naturally occupied by the plants under study.…”

Flood‐induced leaf elongation in Rumex species: effects of water depth and water movements

1995

S U M M A R YSeveral species from the genus Rumex are found in Dutch river forelands. Species such as R. palustris Sm. from the low, frequently flooded areas are well adapted to wet conditions, Rumex species from higher and less frequently flooded sites are poorly adapted and therefore sensitive to flooding. One of the adaptations to flooding is enhanced shoot elongation upon connpiete submergence, enabling plants to restore leaf-air contact, provided that the water is not too deep. This paper demonstrates the strong variation in the absolute extent of flood-induced leaf elongation among species of the genus Rumex. The effects of flooding on shoot dr>' and fresh weight and internal gas \'olunies of an elongating and a non-elongating species, R. palustris and R. acetosetla L,, were compared. Net water uptake in response to complete submergence was observed in the shoots of both species. Based on results presented here, we conclude that in plants of R. palustris water enters the cells and is used for cell expansion leading to petiole elongation, whereas in plants of R. acetosella at least part of the water taken up fills the intercelfular gas spaces. Elongation of complete))* submerged Rumex plants does not vary with different depths of submergence, Tbis was concluded from the observation that there is little effect of either hydrostatic pressure or irradiance on leaf elongation during complete submergence. Howe\ er, when R. palustris plants were subjected to a changing water depth, i.e, alternate periods of complete submergence and waterlogging, they elongated less strongly than under permanent complete submergence. Water movements did not affect leaf elongation induced by submergence.
