Effect of climate, anther morphology and pollination syndrome on pollen availability in Penstemon
Journal of Pollination Ecology, 2023 Traditionally, pollen presentation is thought to be a function of pollinator type and visitation frequency. However, despite the repeated observation that pollen presentation is influenced by flower morphology and abiotic factors, these aspects have been

Pollen Morphology and Sucrose Giving on Stigma Relation with Incompability of Sweetpotato (Ipomoea Batatas (L.) L.) [PDF]
, 2013 The purpose of the research is to examine how to increase cross and self-pollination by solving incompatibility of sweet potato mechanism through sucrose giving on stigma and pollen nuclei checking. Sucrose in different concentration is giving to stigma.
