英國櫟（Quercus robur L.）花粉粒之研究

Experimental Investigations on the Pollen Grains of Quercus robur L.

乾燥、水解及部分崩解之英國櫟（Quercus robur L.）花粉粒藉光學與電子顯微鏡加以研究。以稀釋甘油處理30天之部分溶解花粉以穿透式顯徵鏡研究。根據新實驗資料，英國櫟的孢粉外壁之孢粉質素抗力較差且崩解迅速。孢粉壁內層及原生質抗力較強。統計方法分析花粉粒的對稱性及其他形態的轉換。

Dry, hydrated, and partially degraded pollen grains of Quercus robur L. were investigated with the LM method. The TEM method was used for pollen grains partially dissolved with diluted glycerine for 30 days. Based on the new experimental data, the sporopollenin of the ectexine of this pollen grains is less resistant and may be degraded very quickly. The inner body, which consists of the in tine and protoplasm is more resistant. The symmetry and other morphological alterations of the pollen grains were investigated statistically.
