The feasibility of preservative treatment of gollah cane (Daemonorops jenkinsiana (Griff.) Mart.) by soaking method was tested in the present study. Cane samples of 1m, 2m and 3m long were soaked with 10% borax and boric acid solution. The study revealed that adequate dry salt retention (DSR) in the above samples could be obtained in 3 days, 4 days and 5 days of soaking, respectively. Within these periods the above rattan samples retained 17.77 kg m-3, 14.97 kg m-3 and 15.00 kg m-3 of dry salt. The DSR values obtained were much higher than those of the specification (4 kg m-3) of Indian Standard. Dry cane (12.87% m.c.) samples up to 3m - 4m long could be treated easily within 5 days, but the same dimension of green (150% m.c.) samples needed 8 days. DSR values of air-dried samples were about 7 times higher than that of the green samples.
