Pollen tube incompatibility reaction on the stigma in selfpollinated Sinapis alba L.
Acta Societatis Botanicorum Poloniae, 2014 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.

Oikos, EarlyView.Interspecific pollen transfer (IPT), the pollen movement between plant species via shared pollinators, reduces the reproductive success of pollen‐recipient plants due to hybridization with heterospecific pollen grains. As a result, IPT hinders coexistence of sympatric, co‐flowering species by reducing their reproductive success.

Evaluation of the reproductive process as the cause for low fruit set in two japanese plum cultivars [PDF]
, 2012 The reproductive process has been evaluated to ascertain the causes of low fruit set in two Japanese plum cultivars, ‘Sweet August’ and ‘Rubirosa’. In order to evaluate pollen germination, pollen-pistil incompatibility and ovule viability, different ...

Oikos, EarlyView.Predation is a major ecological force, but its effect on bees has rarely been studied. Here, we investigated whether the presence of the European bee‐eater Merops apiaster, a migratory bird species and major bee predator, decreases the abundance and body size of three common bumblebee species (Bombus lapidarius, B. terrestris and B.

In Vitro Studies on Pollen Viability, Pollen Germination and Pollen Tube Growth of Hornstedtia Conoidea Ridl. – a Philippine Endemic Ginger Species [PDF]
, 2018 Zingiberaceous plants are predominantly propagated through underground rhizomes and seeds. In this study, the viability of pollen, rate of pollen germination and length of pollen tube of the Philippine endemic Hornstedtia conoidea were examined.

Peptide signalling during the pollen tube journey and double fertilization.
Journal of Experimental Botany, 2015 Flowering seed plants (angiosperms) have evolved unique ways to protect their gametes from pathogen attack and from drying out. The female gametes (egg and central cell) are deeply embedded in the maternal tissues of the ovule inside the ovary, while the

Pest Management Science, EarlyView.The larval food consumption, growth, and pectinase activity without symbiotic bacteria are suppressed in Zeugodacus cucurbitae. We isolated four strains of Klebsiella spp. that can participate in pectinolytic metabolism from feeding wounds. Reintroducing them to sterile eggs breaks the developmental constraints caused by the lack of symbiotic bacteria.

Organelle trafficking, the cytoskeleton, and pollen tube growth.
Journal of Integrative Plant Biology, 2015 The pollen tube is fundamental for the reproduction of seed plants. Characteristically, it grows relatively quickly and uni-directionally ("polarized growth") to extend the male gametophyte to reach the female gametophyte. The pollen tube forms a channel
