Pollen Biology of Robinia pseudoacacia on Zhen Mountain in Yantai

Abstract:

The pollen–ovule ratios, pollen fertility rate, pollen viability and longevity, pollen histochemistry of Robinia pseudoacacia flowers were determined in the field on Zhen Mountain in Yantai, Shandong province in China. The main results were as follows: Robinia pseudoacacia is completely fertile and has starchy pollen. The pollen longevity was about 80h. The pollen viability was higher than 90% at the beginning of anthesis on sunny days. 80h later, most pollen grains lose their viability. Pollen–ovule ratio (P/O) is 192±19. Accoring to Cruden, R. pseudoacacia is facultative autogamous.
