Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub

Oikos, EarlyView.
Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...

Factors Influencing Date Pollen Viability

Journal of Agricultural and Marine Sciences, 1997
Pollen of seven date cultivars was stored at 4.5 -5.0'C using desiccator with or without silica gel and in vials outside the desicator as a control. Germination percentage was determined microscopically with a hemacytometer after harvest and at three and

The potential of seedbank digital information in plant conservation

PLANTS, PEOPLE, PLANET, EarlyView.
Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number of maternal plants and seed traits, we can attempt the estimation of genetic ...

Assessment of Pollen Quality and Germination Dynamics in Chestnut (Castanea spp.): Implications of Genotypic Variation and Sucrose Concentration

ISPEC Journal of Agricultural Sciences
Pollen viability and germination are critical factors influencing reproductive success and nut yield in chestnuts (Castanea spp.). However, their dynamics across different genotypes and cultivars remain insufficient.

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

PLANTS, PEOPLE, PLANET, EarlyView.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

Pollen Germination in Some Gramineae [PDF]

Nature, 1961
I. K. VASIL, in his communication under this title in Nature of September 24, p. 1135, states that “this is the first report of a successful germination of the pollen of Gramineae in vitro”. May I point out that the germination of pollen of different varieties of Saccharum officinarum was carried out as a routine practice by the Sugarcane Research ...

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Optimization of in vitro pollen storage conditions in seeded and low-seeded citrus genotypes

Environment Conservation Journal
An in vitro pollen storage study was conducted using pollen from three seeded citrus plant genotypes, viz., ‘Mexican lime’, ‘W’. Murcott’ and ‘Mosambi’ and five seedlesscitrus genotypes, viz., ‘Lisbon lemon’, ‘Jaffa’, ‘Clementine’, ‘Hamlin’ and ‘Mukaku ...

Factors Regulating In Vitro Germination of Date Palm Pollen Grams After Storage

Journal of Agricultural and Marine Sciences, 2000
Dried pollen grains of three date palm (male) cultivars grown in Oman were stored either in a freezer (-18°C), a refrigerator (4 to 5°C), or at room temperature (23 to 25°C) for 6 or 12 months.
