Effect of Sucrose and Boric Acid on in-vitro Pollen Germination of Guava (Psidium guajava) Varieties

, 2018
The Premise of Research: To reproduce, higher plants utilize a unique multicellular microorganism: The male gametophyte, or pollen grain. It is known fact that pollen has a strong impact on physical and biochemical quality of fruit.

The Arabidopsis KINβγ Subunit of the SnRK1 Complex Regulates Pollen Hydration on the Stigma by Mediating the Level of Reactive Oxygen Species in Pollen.

PLoS Genetics, 2016
Pollen-stigma interactions are essential for pollen germination. The highly regulated process of pollen germination includes pollen adhesion, hydration, and germination on the stigma. However, the internal signaling of pollen that regulates pollen-stigma

CNGCs in Marchantia paleacea uncouple arbuscular mycorrhizal symbiosis and rhizoid development

New Phytologist, EarlyView.
Rhizoid growth and AM fungal infection are uncoupled. Summary In Marchantia paleacea, MpaDMI1‐dependent nuclear Ca2+ oscillations are essential for arbuscular mycorrhizal (AM) fungal colonisation, indicating that endosymbiosis‐mediated nuclear Ca2+ signalling is a conserved feature of land plant–AM symbiosis.

Pollen longevity and viability dataset: an integrated resource for plant research and conservation

New Phytologist, EarlyView.
The most common methods to estimate pollen viability. Summary Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse ...

Viability of eggplant pollen [PDF]

Crop Breeding and Applied Biotechnology, 2009
This study aimed to test methodologies to evaluate the pollen viability of eggplant. The pollen germinationwas tested in vitro, incubating the pollen during 0.5 and 16 hours in different sucrose concentrations (0; 2.5; 5.0; 7.5 and10.0 g L-1). For the in

Spatially Resolved ABA Signalling Reveals Dual Role in Tomato Yield

Plant Biotechnology Journal, EarlyView.
ABSTRACT Abscisic acid (ABA) is a central hormonal regulator of plant adaptation to stress and developmental progression. However, its contribution to agronomic traits such as yield remains unclear due to the pleiotropic nature of ABA signalling. To disentangle distinct physiological functions of ABA, we employed a receptor‐specific gain‐of‐function ...

Effect of temperature on pollen germination for several Rosaceae species: influence of freezing conservation time on germination patterns [PDF]

PeerJ, 2019
Between February 2018 and April 2018, flowers were collected from eight Rosaceae species. Flowers were kept in a freezer at −20 °C for three freezing times (Treatment 1, two months; Treatment 2, four months; Treatment 3, six months).

n vitro pollen quantity, viability and germination tests in quince

AFRICAN JOURNAL OF BIOTECHNOLOGY, 2011
Quince (Cydonia oblonga Mill.) cvs. Ekmek, Esme, Limon, Ege 2, Ege 22, Ege 25 and Quince-A rootstock pollens were collected in April from the unopened pink balloon-stage flowers on mature trees. The pollen amount was between 20063 pollen/flower (‘Ege 25’) and 11906 pollen/flower (‘Limon’) with hemacytometer. The lowest and highest pollen viability were
