| 中文摘要: |
| 为了研究菠萝花期性状特点，于 2009-2011 年对引种定植的 20 份菠萝种质进行花期性状的观测。结果表明，菠萝花期约 11-37 d，单朵小花花期 1 d。花期的长短在种质间、个体间以及年度间存在差异。菠萝花冠、花药形态、花粉、花丝颜色种质间无明显的区别。萼片颜色、苞片和花柱特征因种质而异。花期如遇低温阴雨，有些菠萝种质会出现雄蕊败育现象。 |
| 英文摘要: |
| To research the florescence characteristics of pineapple, observations of 20 pineapple germplasms were conducted during the flowering seasons from 1999 to 2001. The results showed that natural flowering period of the whole inflorescence is approximate 11-37 days, and that of the single fruit floret lasted only 1 day. The length of flowering period varied among different germplasms, individual plants and growing years．No significant difference was found among corolla, anther morphology, pollen and filament color of pineapple in different germplasms. However, sepal color, characteristics of the bracts and style were influenced by varieties. Some germplasms appeared the phenomenon of stamens sterility in case of low temperature and rainy weather during flowering period. |
