Abstract

Growth of Suaeda maritima was stimulated by low aluminium concentrations in saline solution culture with an increase in the number and extent of lateral roots. Under non-saline conditions the same Al concentrations inhibited growth and led to an abnormal lateral root initiation. Increasing the level of Al led to growth inhibition under both culture conditions.

Salinity reduced the uptake of A1 into plant tissue, and there was no evidence that A1 was tolerated internally. Although short-term 32P influx was increased by A1 there were no long-term effects of significance on levels of Na, K, Ca nor P in the shoots.

The results are discussed in relation to proposed mechanisms of A1 toxicity and the interaction between A1 and salt toxicities. An explanation is proposed for both stimulatory and inhibitory effects of A1 as a quantitative expression of a single primary effect upon the root system.
