Pollen tube incompatibility reaction on the stigma in selfpollinated Sinapis alba L.
After selfpollination of Sinapis alba L. pollen tubes growth is inhibited on the stigma. The pollen grains germinate 3-4 hours after pollination. The pollen give rise to one or more pollen tubes. They grow along the papillae.

ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing

Collapsing pollen grains [PDF]
Pollen grains come in all sorts of shapes - they can be spherical, ellipsoidal, lobate, prismatic, polyhedral, and then, there are some which escape easy qualification in terms of geometry. The sizes also differ very much, from less than 10 micrometers (e.g.

Evaluation of Pollen Vitality in Different Sugarcane Genotypes Utilizing Various Techniques and Time Intervals [PDF]
This study was conducted to contrast two staining techniques for determining pollen viability in sugarcane. At three diverse times (6:30, 8:00, and 9:30 a.m.), pollen from seven sugarcane genotypes was gathered, and its vitality was assessed using ...

Assessing corn pollen flow and outcross in seed and grain production fields [PDF]
Pollen movement and the resulting flow of genes between plant populations have been an integral part of corn evolution. However, the adventitious presence of bioengineered genes in conventional varieties due to gene flow is a serious concern when ...

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...
