Seeds from three widely differing provenances in Tasmania were tested to determine whether they had different responses to various dormancy-breaking treatments. In our case we have used three different color thread. For Many Acacia seeds the breaking of the dormancy occurs with heat and although smoke and ash stimulate seed germination for many species with hard coats, heat is the main factor influencing the germination of Acacia decurrens. You can use other seed too. The intention for this experiment was to determine whether the effects of heat increased or decreased the rate at which Acacia decurrens germinated. is especially suitable for planting to control water erosion in areas such as river-banks and eroded paddocks [5]. h��V�o�6�W��`$Q$%E ǮWcmV��2����� [2$���ݝH�R�f���p��x_��2�XȤY���$���8Rp�L(�`���劥a 72hrs| 73%| Control 1| 0| 15| 0| 0| Control 2| 0| 15| 0| 0| Both Heat treated groups 1 & 2 had seeds that germinated within 3-4 days of receiving this heat treatment. h�bbd``b`z$[A��`������@�y%�[bɂ�� ��8�0�S�@�A/#�L���h���;� I $ Of the 1193 seeds planted 1071 are included in the analyses (122 are excluded because another species than A. tortilis germinated).
