Abstract

The volume of hydrated pollen grains of Petunia hybrida L. during swelling in germination medium increased three times. The volume of desiccated pollen grains increased only two times after transfer to the same medium. This difference in swelling ability is attributed to different rigidities of the pollen grain wall,ccaused by the different hydration states. The relationship between pollen grain swelling and germination metabolism with regard to relative humidity is discussed.

摘要

在萌发介质中，矮牵牛（Petunia hybrida L.）水合花粉粒的体积在膨胀过程中增加了三倍。将干燥花粉粒转移到相同的介质中后，体积仅增加了两倍。这种膨胀能力的差异归因于花粉壁的不同刚性，这是由不同的水合状态引起的。本文还讨论了花粉粒膨胀与相对湿度下萌发代谢之间的关系。
