“…Australian edible seeded acacias have great potential for combating hunger in semi-arid lands (Thomson et al 1994;Harwood et al 1999;Rinaudo et al 2002). The seeds have a long storage life and are tasty, safe to consume and nutritious: protein, carbohydrate and fat contents are 17-25%, 30-40% and 14-16% respectively (Brand and Cherikoff 1985;Adewusi et al 2003).…”

“…It is one of the most promising genera for arid, saline areas and includes species which provide a range of useful products and functions (Thomson et al, 1994). Seeds of the multipurpose legume trees Acacia coriacea and A. tortilis lost Ca and K when incubated in NaCl solutions, with the salt-tolerant A. tortilis losing more Ca and less K than the salt-sensitive A. coriacea (Rehman et al, 1996).…”

Seeds of Acacia coriacea DC. and A. tortilis (Forsk.) Hayne were soaked for 10 h in distilled water (DW), or in 10 or 50 mM CaCl 2 , Ca(NO 3 ) 2 , KC1 and KNO 3 Seeds were air dried and germinated in DW or NaCl at their predetermined LD 50 ,125 mM for A coriacea and 375 mM for A tortilis. No treatments significantly increased final germination in D W but DW treatment significantly increased final germination of A. tortilis in NaCl. Treatment with calcium (Ca) or potassium (K) salts did not give a significantly greater final germination than treatment with DW. The rate of germination both in D W and NaCl increased with all treatments. There were significant differences in the Ca and K contents of seeds after treatment, and in the net loss of Ca and K during subsequent soaking in NaCl. In this study seeds treated with CaCl 2 absorbed the same amount or less sodium (Na) from NaCl solutions as did DW-treated seeds, while KCl-treated seeds took up as much or more Na as did DW-treated seeds. However, these differences do not appear to be related directly to the effectiveness of presowing seed treatments in increasing germination and germination rate. Treatment with DW and drying is a rapid 277

“…WUE of Changium smyrnioides and Anthriscus sylvestris also increased with the decrease of soil moisture (Ge et al 2003). Thomson et al (1994) reported that some Australian Acacia species withstand long dry periods. These observations may be explained by high water-use efficiency of A. ampliceps determined in our study.…”

Acacia ampliceps Maslin and Eucalyptus camaldulensis Dehnh. were grown for one year in lysimeters at three soil moisture regimes: 100 % (well-watered), 75 % (medium-watered) and 50 % (low-watered) of total plant available water. Biomass yield of both species increased with increase in soil moisture. Water-use efficiency (WUE) of E. camaldulensis decreased and that of A. ampliceps increased markedly with decrease in available soil moisture. A. ampliceps showed 4 -5 times more biomass yield than E. camaldulensis grown at similar soil moisture. A. ampliceps showed almost 5, 9 and 12 times higher WUE than E. camaldulensis under low-, medium-and well-watered treatments, respectively. Significant negative correlation of δ 13 C with WUE (r = -0.99) was observed in A. ampliceps. In contrast, δ 13 C of E. camaldulensis showed a significant positive correlation with WUE (r = 0.82).Additional key words: biomass production, plant available soil water, transpiration efficiency.
