| 摘 要： | 在南京地区进行美洲狼尾草（Ｐｅｎｎｉｓｅｔｕｍａｍｅｒｉｃｕｎｕｍ）与象草（Ｐ．ｐｕｒｐｕｒｅｕｏｎ）的种间杂交，对象草作短日照处理，以诱导其抽穗，开花。通过对象不同移栽期，不同短日照处理天数的试验及对影响花粉量诸因子的综合分析表明，较早移栽植象草（５月５日移栽）覆膜２１ｄ能有效提高父本的花粉量。

| Abstract: | Pennisetum americunum and P. purpureum must be treated by short day so as to induce them heading and flowering before they hybridize in Nanjing area. By comprehensive analysis of different transplanting stage, different short days treatment and the factors of influencing pollen numbers, the results showed that ealier transplanting (5 May.) and covering 25 days could effectively increase the pollen numbers of father plants. |
