Effect of Hapalosiphon fontinalis (Ag.) Bornet extracts (aqueous and methanolic extracts) at the concentrations of 0, 25, 50, 75 and 100 g(DW)/l on ammonia content in giant mimosa (Mimosa pigra L.), painted spurge (Euphorbia heterophylla L.), leaf mustard (Brassica juncea (L.) Czern.), soybean (Glycine max L.) finger grass (Chloris barbata Sw.) and rice (Oryza sativa L. cv. Khao Dawk Mali 105) was investigated. The results showed that the high concentration of aqueous extract increased ammonia accumulation in shoot and root of giant mimosa, painted spurge, finger grass and rice whilst methanolic extract increased ammonia content only in root of giant mimosa and shoot of leaf mustard. The results also indicated that each plants had differential response on H. fontinalis extract. Aqueous and methanolic extracts were different in induction of ammonia accumulation.
