| 摘 要： | 介绍了南方红壤区治理水土流失常见的构树、火棘、黄栀子、鬼针草4种耐干旱植物种子,对其进行质量检验和萌发试验,以期为南方红壤区植被恢复增加可供选择的先锋植物,结果表明:(1)4种植物种子净度都在90%以上;(2)构树、鬼针草的种子含水量分别为11.20%、14.15%,种子干藏保存;而火棘、黄栀子的种子含水量分别为87.83%、86.95%,种子应沙藏保存;(3)火棘种子在5～7℃即可萌发,鬼针草在8～15℃时萌发,构树、黄栀子的种子萌发温度为24.5～27.5℃;(4)供试植物种子均不存在休眠性。

| Abstract: | In order to increase the diversity of available pioneer plants for vegetation restoration works in red soil region of southern China,we studied the seed quality and germination regularity of four drought-tolerant plants Broussonetia papyrifera,Pyracantha fortuneana,Gardenia jasminoides and Bidens pilosa,which were primary pioneer plants for controlling water and soil erosion in red soil region of southern China.The results showed that:(1) The seed purity of these four plants was all above 90%;(2) The water contents in the seeds of Broussonetia papyrifera and Bidens pilosa were 11.20% and 14.15% respectively,and they were suitable for dry storage.However,the water contents in the seeds of Pyracantha fortuneana and Gardenia jasminoides were 87.83% and 86.95% respectively,and they were appropriate for sand storage;(3) The temperatures for the seed germination of Pyracantha fortuneana,Bidens pilosa were 5 ～ 7 ℃ and 8 ～ 15 ℃,respectively.The seeds of Broussonetia papyrifera and Gardenia jasminoides could germinate at 24.5 ～ 27.5 ℃;(4) All the tested seeds had no dormancy. |
