Abstract: BACKGROUND AND AIMS Post-pollination pre-zygotic barriers involve interactions between pollen, pistil, and ovules that impede fertilization by heterospecific pollen. These barriers act sequentially when pollen from different donors simultaneously pollinates the same flower, by inhibiting… read more here.

Abstract: Reproductive growth is a bioenergetic process with high energy consumption. Pollination induces female flower longevity in spinach by accelerating sepal retention and development. Cellular bioenergetics involved in cellular growth is at the foundation of all… read more here.

DOI: 10.3389/fpls.2022.908852
Abstract: Comparison and quantification of multiple pre- and post-pollination barriers to interspecific hybridization are important to understand the factors promoting reproductive isolation. Such isolating factors have been studied recently in many flowering plant species which seek… read more here.
