| 摘要: |
| 通过调查与试验,研究了天麻生殖生长期的抽薹、开花习性,并分析了不同授粉方式对天麻果实及种子质量的影响。结果表明,天麻单株花期3～10 d不等,花序轴单花数目视个体发育不同而差异较大;天麻抽薹及果实膨大的生长发育均呈“S”型曲线,可用一元二次方程式表述;不同授粉方式虽在座果率上无明显差异,但异花授粉可明显提高天麻种子的质量。 |

| Abstract: |
| The reproductive growth of Gastrodia elata Bl.and the relation of the seed quality and pollination methods have been analyzed through experiment and research.The result shows that the number of flower is significantly different among the stems,and the growth dynamic regularity of reproductive organs is similar.Though the ratios of fruit set are not same,the quality of seeds got from allogamy is better. |
| Key words: Gastrodia elata Bl. reproductive biology artificial pollination allogamy |
